The Micro-Grid Fleece Liner is JRB's everyday option — soft, warm, and simple. Layer it inside any JRB quilt or sleeping bag to add 10–15°F of warmth, or shake it out on its own as a fleece camping blanket when the full setup is more than you need. No backpacking price tag. No moisture-wicking claims.

Whether you’re pushing your sleeping bag into shoulder-season territory or heading out on a warm-weather overnight with nothing but this, it’s the layer that earns its weight.\u003c\/p\u003e\n\u003ch2\u003eWhat makes it different\u003c\/h2\u003e\n\u003cp\u003ePolartec Alpha Direct skips the shell fabric entirely — the insulation is the surface, designed to sit directly against your skin. That means less bulk, faster drying, and a next-to-skin softness you won’t find in a standard sleeping bag liner. Unlike other fabrics that go clammy when temperatures and humidity climb, Alpha Direct stays soft and dry against your skin — no sticking, no cling, no matter how muggy it gets. Use it as a standalone summer quilt on warm nights, a versatile camping liner for any sleep system, or a packable backpacking liner that pulls its weight on thru-hikes, weekend trips, and nights at home alike. \u003cem\u003eTrail Tested.

The Shenandoah is cut for people who sleep on their back, don't thrash around much, and want a summer quilt that's as practical in a hammock as it is on the ground. At 48 inches across, it covers you fully without pooling underneath you or bunching when you roll to a side. Snaps and a drawcord at the head end form shoulder pockets that seal out drafts at the neck when temperatures approach the rating — giving you control without restricting movement. If you're a back sleeper on a summer through-hike or a hammock camper who wants one quilt that handles both ends of a warm night — this is it. A wide quilt will give you excess you don't need. The Shenandoah won't.\u003c\/p\u003e\n\n\u003ch2\u003eHow It Gets to 14.5 oz: 850 Fill Power Down, 1.1 oz Taffeta Shell\u003c\/h2\u003e\n\n\u003cp\u003eThe Shenandoah is filled with 850 Fill Power RDS-certified down. Fill power measures how many cubic inches of loft one ounce of down produces when fully expanded — at 850FP, the Shenandoah reaches its 40°F rating with less fill by weight than quilts built with lower-grade down. The shell is 1.1 oz taffeta with a DWR coating that sheds light moisture and condensation. Backpackers who want to shave weight can step up to the \u003ca href=\"\/products\/shenandoah-ultralight-40-degree-multifunction-summer-backpacking-quilt\"\u003eUltralight Shenandoah\u003c\/a\u003e, which uses 1000FP down and Argon 67 shell to reach 11.5 oz at the same 40°F rating.\u003c\/p\u003e\n\n\u003cp\u003eThe Shenandoah is sewn through rather than box-baffled — shell stitched directly to the lining, with no internal fabric walls. That is the right build at 40°F: a summer quilt is not asked to hold deep loft, so the walls and extra fabric a box baffle needs would add weight and cost for warmth you would not use. JRB box-baffles the 20°F and 0°F quilts, where full loft decides whether the rating holds, and leaves it out here so the Shenandoah can come in at 14.5 oz.\u003c\/p\u003e\n\n\u003cp\u003eEvery Shenandoah ships with a 25% overstuff by weight. Down naturally migrates toward the ends of each baffle over time, leaving the center of each baffle thinner. The extra fill means every section retains enough loft to hold the 40°F rating even after downshifting occurs — no cold spots through the middle of the quilt. The same buffer compensates for loft loss as the down accumulates oils between cleanings.\u003c\/p\u003e\n\n\u003cp\u003eThe foot box is formed using a drawcord, cord-locks, and double-sided Kam Snaps. Snap it closed on cool nights for a sealed foot pocket; leave it open on warm nights and use it as a blanket.\u003c\/p\u003e\n\n\u003ch2\u003eStack It With Another Quilt for Colder Nights\u003c\/h2\u003e\n\n\u003cp\u003eThe double-sided Kam Snaps do more than close the foot box.

Any temperature combination works, multiples of the same rating included. Quilts made from 2019 on have the snaps; before that we used Omni Tape, which doesn't stack. Every JRB quilt you own makes the next one warmer.\u003c\/p\u003e\n\n\u003cp\u003eAt 14.5 oz, the Shenandoah is the lightest 40°F multifunction quilt in the JRB lineup — light enough for a summer through-hike and versatile enough to run as a hammock underquilt when the trip calls for it.\u003c\/p\u003e\n\n\u003ch2\u003eAlso Works as a Hammock Underquilt\u003c\/h2\u003e\n\n\u003cp\u003eThe Shenandoah attaches to your hammock using the JRB Underquilt Suspension System (sold separately) and insulates against the cool air beneath on warm nights. The rectangular shape conforms cleanly to the hammock's hang without bunching. Ease the end draw cords off and the quilt eases away from the hammock, letting air move across your back — we call it \u003cstrong\u003eopening the windows\u003c\/strong\u003e, and it is handy on the nights you climb in hot. It fits all gathered-end and bridge hammocks including ENO, Hennessy, Warbonnet, Dutchware Chameleon, and most DIY designs.\u003c\/p\u003e\n\n\u003ch2\u003eNamed for the Trail\u003c\/h2\u003e\n\n\u003cp\u003eShenandoah is where families discover camping. The campgrounds along Skyline Drive sit at 3,500 feet, tucked into the oak and hickory forest of the Blue Ridge — close enough to drive in on a Friday afternoon, far enough from everything else that the phones lose signal and nobody minds. The deer walk through camp at dusk. The fireflies come out after dark. The kids roast marshmallows until the fire goes to coals.\u003c\/p\u003e\n\n\u003cp\u003eThe temperature drops faster than anyone expected.

A sew-through quilt skips those walls and stitches the two layers straight to each other, so every seam is a strip of pinched fabric with no insulation in it. Those strips are cold spots, and you feel them at 20°F. Box baffles take longer to build and add a little weight, which is why they are the first thing cut from cheaper three-season quilts.\u003c\/p\u003e\n\n\u003cp\u003eEvery Hudson River ships with a 25% overstuff by weight. Down naturally migrates toward the ends of each baffle over time, leaving the center of each baffle thinner. The extra fill means every section retains enough loft to hold the 20°F rating even after downshifting occurs — no cold spots through the middle of the quilt. The same buffer compensates for loft loss as the down accumulates oils between cleanings.\u003c\/p\u003e\n\n\u003cp\u003eThe foot box is formed using a drawcord, cord-locks, and double-sided Kam Snaps.

The Old Rag Mountain is cut for people who sleep on their back, don't thrash around much, and don't want to carry excess fabric into a winter pack. At 48 inches across, it covers you fully without pooling underneath you or bunching up when you roll to a side. If you're an average to lean build and a relatively still sleeper — think 5'10\", 165 lbs, a back sleeper who heads out in January and occasionally drifts onto a side — this is the quilt. The extra width of a wide winter quilt will get in the way. The Old Rag Mountain won't.\u003c\/p\u003e\n\n\u003ch2\u003eHow It Gets to 27 oz: 850 Fill Power Down, 1.1 oz Taffeta Shell\u003c\/h2\u003e\n\n\u003cp\u003eThe Old Rag Mountain is filled with 850 Fill Power RDS-certified down — deep, resilient loft that holds its warmth season after season. RDS stands for Responsible Down Standard, an independent certification that verifies animal welfare throughout the supply chain. Fill power measures how many cubic inches of loft one ounce of down produces when fully expanded — at 850FP, the Old Rag Mountain achieves its 0°F rating with less fill by weight than quilts built with lower-grade down. The shell is 1.1 oz taffeta with a DWR coating that sheds light moisture and condensation.\u003c\/p\u003e\n\n\u003cp\u003eAt 0°F, construction matters as much as the fill number. The Old Rag Mountain is box-baffled — internal fabric walls form enclosed chambers so the down can stand to its full height across the whole quilt. Sew-through construction takes the shortcut, running stitches straight through shell and lining, and each of those lines is a band of crushed fabric carrying no insulation at all. In January those bands are where the heat leaves, and box baffles — slower to build, slightly heavier, more expensive — are the reason this quilt holds a true winter rating.\u003c\/p\u003e\n\n\u003cp\u003eEvery Old Rag Mountain ships with a 25% overstuff by weight. Down naturally migrates toward the ends of each baffle over time, leaving the center of each baffle thinner.

In the early days, the two Jacks planned a weekend loop through central Shenandoah National Park. They loaded up with what gear they had — 3–5 pound sleeping bags, a 5-pound tent, self-inflating pads — and set off with 35–40 pound external frame packs. Old Rag was on the route. One of them had hiked it in his younger days. The upper section is a rock scramble, a fun trip. Key word: younger.\u003c\/p\u003e\n\n\u003cp\u003eThey made it over Old Rag just fine. What nearly finished them was the climb back up White Oak Canyon to the ridge — two fifty-something guys, 40-pound packs, a mountain they hadn't been on in years. At the top, they called it. Motel. Hot showers. A big steak dinner. They drove home the next day and, as Jack tells it, \"have never heard the end of it from our wives.\"\u003c\/p\u003e\n\n\u003cp\u003eOver the next couple of years they replaced every heavy piece of kit with something lighter — sleeping bags, tents, pads, packs — and eventually started making their own quilts. Jacks R Better was born out of two guys who got whipped by a mountain and refused to let it happen again. The Old Rag Mountain quilt carries that name because this is where the story started.\u003c\/p\u003e\n\n\u003cp\u003eHandmade in Pennsylvania by Jacks R Better — making quilts since 2004.

That width across the shoulders and torso keeps side sleepers covered through the night — critical at 0°F when there is no margin for a quilt that rides up. The narrower foot section eliminates dead air and excess weight without sacrificing the coverage that matters.

Down naturally migrates toward the ends of each baffle over time, leaving the middle of the baffle thinner and reducing effective insulation across the full length of the quilt. The extra fill ensures that even after downshifting has occurred, every section of every baffle retains enough loft to hold the 0°F rating — in a winter quilt, cold spots through the center of the quilt are not recoverable on a frozen night. No additional overstuffing is needed or recommended.

A sleeping bag used underneath is simply not doing what it was designed to do. An underquilt solves this by hanging freely below the hammock fabric — it never touches your body, never gets compressed, and the down stays fully lofted all night.\u003c\/p\u003e\n\n\u003cp\u003eWithout an underquilt, no amount of insulation on top of you will keep you warm below 50°F in a hammock.

It is the thing that separates a purpose-built underquilt from a top quilt repurposed underneath. The inner shell is cut smaller than the outer shell, so the quilt conforms to the curved underside of a loaded hammock instead of the two shells pulling together at the edges and compressing the down between them. A flat-cut quilt compresses the down exactly where it matters most as it curves around the hammock. The baffles run radially to follow the contour of your body, which is what holds loft height constant from head to foot as the hammock changes shape under you.\u003c\/p\u003e\n\n\u003cp\u003eSuspension is by adjustable shock-cord loops at each end, included — and \u003cstrong\u003eyou cannot hang it too tight\u003c\/strong\u003e. Because the outer shell is cut larger, it keeps its slack no matter how far you pull the suspension down, so tightening seals the edges against draughts instead of crushing the loft. Ease those same cords off instead and the quilt eases away from the hammock, letting air move across your back — we call it \u003cstrong\u003eopening the windows\u003c\/strong\u003e, and it is handy on the nights you climb in hot. You also \u003cstrong\u003ecannot be too warm underneath\u003c\/strong\u003e — the same reason you sleep on the same mattress in July as in January. An underquilt warms only your back; the rest of you stays open to the air, so there is no sealed pocket to trap heat the way a sleeping bag does.

A sleeping bag used underneath cannot solve that. An underquilt hangs freely below the hammock shell, never touching you, so the down stays fully lofted and delivers its rated insulation from below.

It is the thing that separates a purpose-built underquilt from a top quilt repurposed underneath. The inner shell is cut smaller than the outer shell, so the quilt conforms to the curved underside of a loaded hammock instead of the two shells pulling together at the edges and compressing the down between them. The baffles run radially to follow the contour of your body, which is what holds loft height constant from head to foot as the hammock changes shape under you.\u003c\/p\u003e\n\n\u003cp\u003eSuspension is by adjustable shock-cord loops at each end, included — and \u003cstrong\u003eyou cannot hang it too tight\u003c\/strong\u003e. Because the outer shell is cut larger, it keeps its slack no matter how far you pull the suspension down, so tightening seals the edges against draughts instead of crushing the loft. Ease those same cords off instead and the quilt eases away from the hammock, letting air move across your back — we call it \u003cstrong\u003eopening the windows\u003c\/strong\u003e, and it is handy on the nights you climb in hot.

The underquilt changed that — hung below the hammock, fully lofted, sealed at the ends, it turned a hammock into a warm, enclosed sleeping system. The name came naturally: you were no longer just hanging in a hammock. You were nested.\u003c\/p\u003e\n\n\u003cp\u003eThe Nest is the product that started Jacks R Better.

At 0°F that margin matters more than on any three-season quilt, because a quilt that has quietly drifted to a 10°F reality is a problem you discover at two in the morning.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy 25% here and 36% on our differential-baffle quilts?\u003c\/strong\u003e Because they are not the same quilt underneath. A box baffle is fully and correctly filled at 25%; the curved, differential-cut chambers in the Mt Washington and Greylock series behave differently under load and need 36% to do the same job. The smaller number is not a smaller effort or a cheaper build — it is the figure this construction calls for.

There was no product like it. Hennessy campers had been wrestling with pads and improvised solutions, waking up cold, and making do. The underquilt changed that — hung below the hammock, fully lofted, sealed at the ends, it turned a hammock into a warm, enclosed sleeping system. The name came naturally: you were no longer just hanging in a hammock. You were nested.\u003c\/p\u003e\n\n\u003cp\u003eThe Winter Nest takes that same design into 0°F territory — for Hennessy hammock campers who don't stop when the temperature drops. Twenty-two years after we built the first one, we are still the people who make it, and we still put more down in it than the rating asks for.\u003c\/p\u003e\n\n\u003cp\u003eHandmade in the USA by Jacks R Better, sewn in Pennsylvania — making quilts since 2004.

We invented it at Jacks R Better and have been sewing underquilts this way since 2004. The inner shell is cut smaller than the outer shell, so the quilt conforms to the curved underside of a loaded hammock instead of the two shells pulling together at the edges and compressing the down between them. The baffles run radially to follow the contour of your body, which is what holds loft height constant from end to end as the hammock changes shape under you.\u003c\/p\u003e\n\n\u003cp\u003eSuspension is full-length channeled shock cord with adjustable ends and corner mounting tabs — and \u003cstrong\u003eyou cannot hang it too tight\u003c\/strong\u003e. Because the outer shell is cut larger, it keeps its slack no matter how far you pull the suspension down, so tightening seals the edges against draughts instead of crushing the loft.

If you're tall and lean — think 6'3\", 200 lbs, a back sleeper who occasionally drifts onto a side — this is the quilt for summer nights. The extra width of a wide quilt will get in the way. The Shenandoah won't.

A 40°F rating takes far less down than a colder quilt, and at 1000FP that down is doing its job more efficiently than 850FP alternatives — which is how this quilt comes in at 11.5 oz without compromising warmth. The shell is Argon 67 — a 0.67 oz nylon certified downproof with a DWR finish — the lightest shell fabric in the JRB lineup.\u003c\/p\u003e\n\n\u003cp\u003eWeight is where this quilt makes its argument, and sewn-through construction is part of how it wins. Shell and lining are stitched directly to each other instead of being separated by the internal fabric walls a box baffle requires — that takes fabric, thread, and labor out of the quilt, and the stitch lines still divide it into baffles that keep the down where you put it. At 40°F there is no deep loft to protect, so those walls would be weight spent on warmth you would never call on. JRB builds box baffles into its 20°F and 0°F quilts because a cold-weather rating lives or dies on full loft; here the rating does not ask for it, and that is part of how this became the lightest quilt JRB builds.\u003c\/p\u003e\n\n\u003cp\u003eEvery Shenandoah Ultralight 40°F ships with a 25% overstuff by weight. Down naturally migrates toward the ends of each baffle over time, leaving the center of each baffle thinner. The extra fill means every section retains enough loft to hold the 40°F rating even after downshifting occurs — no cold spots through the middle of the quilt.

That width across the shoulders and torso is what keeps side sleepers covered when they shift positions — there's enough quilt to stay tucked around you rather than riding up. The narrower foot section eliminates dead air and excess fabric without sacrificing the coverage that matters. A snap-and-drawcord system at the head end forms shoulder pockets that seal out drafts at the neck on colder nights. The Big Meadows Ultralight is a dedicated top quilt for ground sleepers and tent campers.\u003c\/p\u003e\n\n\u003cp\u003eThe Big Meadows Ultralight 40° is filled with 1000 Fill Power RDS-certified down — the highest-grade down available. Fill power measures how many cubic inches of loft one ounce of down produces when fully expanded. At 1000FP, significantly less down by weight is needed to reach the 40°F rating compared to 850FP alternatives, which is how this quilt reaches 13 oz without compromising warmth.

Down naturally migrates toward the ends of each baffle over time, leaving the middle of the baffle thinner and reducing effective insulation across the full length of the quilt. The extra fill means that even after downshifting has occurred, every section of every baffle retains enough loft to hold the 40°F rating — you don't end up with cold spots through the center of the quilt where the fill has thinned out. The same buffer also compensates for loft loss as the down accumulates dirt and oils between cleanings. No additional overstuffing is needed or recommended.

At 48 inches across, it covers you fully without pooling underneath you or bunching up when you roll to a side. If you're tall and lean — think 6'3\", 200 lbs, a back sleeper who occasionally drifts onto a side — this is the quilt. The extra width of a wide quilt will get in the way.

Those seams are the cold stripes people report in cheap 20°F quilts.

Also runs as a hammock underquilt.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch2\u003eBuilt for Back Sleepers and Trim Builds Who Need 0°F Without the Weight of a Sleeping Bag\u003c\/h2\u003e\n\n\u003cp\u003eWide winter quilts are cut for side sleepers, larger frames, and restless movers who need that extra coverage when the temperature drops hard. The Old Rag Mountain is cut for people who sleep on their back, don't thrash around much, and don't want to carry excess fabric into a winter pack. At 48 inches across, it covers you fully without pooling underneath you or bunching up when you roll to a side. If you're an average to lean build and a relatively still sleeper — think 5'10\", 165 lbs, a back sleeper who heads out in January and occasionally drifts onto a side — this is the quilt. The extra width of a wide winter quilt will get in the way. The Old Rag Mountain won't.\u003c\/p\u003e\n\n\u003ch2\u003eHow It Gets to 22.2 oz: 1000 Fill Power Down, Argon 67 Shell\u003c\/h2\u003e\n\n\u003cp\u003eThe Old Rag Mountain is filled with 1000 Fill Power down — the highest-grade down available. At 1000FP, significantly less down by weight is needed to reach a 0°F rating compared to 850FP alternatives, which is what keeps a winter quilt under 1.5 lbs. The shell is Argon 67 — a 0.67 oz nylon certified downproof with a DWR finish — the lightest shell fabric in the JRB lineup. Those two choices together are the reason the Old Rag Mountain hits 22.2 oz at a 0°F rating.\u003c\/p\u003e\n\n\u003cp\u003eLoft is the whole game at 0°F, and box baffles are how it gets protected. Fabric walls run between shell and lining to make boxed-off chambers, giving the 1000FP down room to reach full thickness instead of being pinned flat. Sew-through quilts stitch the two layers directly together, which puts a line of compressed, uninsulated fabric at every seam — a grid of cold spots you cannot fix from inside the quilt at 2 a.m. It is the more expensive way to build and it carries a small weight penalty, and at 22.2 oz for a full winter rating that penalty is already paid.\u003c\/p\u003e\n\n\u003cp\u003eEvery Old Rag Mountain Ultralight ships with a 25% overstuff by weight. Down naturally migrates toward the ends of each baffle over time, leaving the center of each baffle thinner. The extra fill means every section retains enough loft to hold the 0°F rating even after downshifting occurs — no cold spots through the middle of the quilt. The same buffer compensates for loft loss as the down accumulates oils between cleanings.\u003c\/p\u003e\n\n\u003cp\u003eThe foot box is formed using a drawcord, cord-locks, and double-sided Kam Snaps. Snap it closed on the coldest nights for a sealed foot pocket; leave it open on warmer nights and use it as a blanket.\u003c\/p\u003e\n\n\u003ch2\u003eStack It With Another Quilt for Colder Nights\u003c\/h2\u003e\n\n\u003cp\u003eThe double-sided Kam Snaps do more than close the foot box.

Every JRB quilt you own makes the next one warmer.\u003c\/p\u003e\n\n\u003cp\u003eAt 22.2 oz, the Old Rag Mountain carries a full 0°F temperature rating into the backcountry — light enough to justify in a winter pack, and warm enough when temperatures drop hard overnight. This quilt was built for backpackers who refuse to call off a trip because of cold weather.\u003c\/p\u003e\n\n\u003ch2\u003eAlso Works as a Hammock Underquilt\u003c\/h2\u003e\n\n\u003cp\u003eThe Old Rag Mountain attaches to your hammock using the JRB Underquilt Suspension System (sold separately) and insulates against the cold air beneath — the primary cause of cold-weather hammock discomfort. Ease the end draw cords off and the quilt eases away from the hammock, letting air move across your back — we call it \u003cstrong\u003eopening the windows\u003c\/strong\u003e, and it is handy on the nights you climb in hot. It fits all gathered-end and bridge hammocks including ENO, Hennessy, Warbonnet, Dutchware Chameleon, and most DIY designs.\u003c\/p\u003e\n\n\u003ch2\u003eNamed for the Trail\u003c\/h2\u003e\n\n\u003cp\u003eOld Rag Mountain is where Jacks R Better started. In the early days, the two Jacks planned a weekend loop through central Shenandoah National Park. They loaded up with what gear they had — 3–5 pound sleeping bags, a 5-pound tent, self-inflating pads — and set off with 35–40 pound external frame packs. Old Rag was on the route. One of them had hiked it in his younger days. The upper section is a rock scramble, a fun trip. Key word: younger.\u003c\/p\u003e\n\n\u003cp\u003eThey made it over Old Rag just fine. What nearly finished them was the climb back up White Oak Canyon to the ridge — two fifty-something guys, 40-pound packs, a mountain they hadn't been on in years. At the top, they called it. Motel. Hot showers. A big steak dinner. They drove home the next day and, as Jack tells it, \"have never heard the end of it from our wives.\"\u003c\/p\u003e\n\n\u003cp\u003eOver the next couple of years they replaced every heavy piece of kit with something lighter — sleeping bags, tents, pads, packs — and eventually started making their own quilts. Jacks R Better was born out of two guys who got whipped by a mountain and refused to let it happen again. The Old Rag Mountain quilt carries that name because this is where the story started.\u003c\/p\u003e\n\n\u003cp\u003eHandmade in Pennsylvania by Jacks R Better — making quilts since 2004.

That width across the shoulders and torso keeps side sleepers covered through the night — critical when temperatures drop to zero and there is no margin for a quilt that rides up. The narrower foot section eliminates dead air and excess weight without sacrificing the coverage that matters. A snap-and-drawcord system at the head end forms shoulder pockets that seal out drafts at the neck. The Big Meadows Ultralight 0° is a dedicated top quilt for ground sleepers and winter tent campers.\u003c\/p\u003e\n\n\u003ch2\u003eHow It Gets to 22 oz: 1000 Fill Power Down, Argon 67 Shell\u003c\/h2\u003e\n\n\u003cp\u003eThe Big Meadows Ultralight 0° is filled with 1000 Fill Power RDS-certified down — the highest-grade down available. Fill power measures how many cubic inches of loft one ounce of down produces when fully expanded. At 1000FP, significantly less down by weight is needed to reach the 0°F rating compared to 850FP alternatives — the primary reason this quilt achieves a true winter rating without the bulk of a conventional sleeping bag.

Down naturally migrates toward the ends of each baffle over time, leaving the middle of the baffle thinner and reducing effective insulation across the full length of the quilt. The extra fill means that even after downshifting has occurred, every section of every baffle retains enough loft to hold the 0°F rating — in a winter quilt, cold spots through the center of the quilt are not recoverable on a frozen night. The same buffer also compensates for loft loss as the down accumulates dirt and oils between cleanings. No additional overstuffing is needed or recommended.

While 1000FP down is the primary reason the UL version weighs less than the standard Big Meadows 0°, the Argon 67 shell contributes to the difference as well.

Instead of just trapping heat, it dumps moisture vapor about as fast as your body makes it, so you stay warm without waking up clammy. It’s lofty, next-to-skin soft, and packs down small.\u003c\/p\u003e\u003cp\u003eThe catch with any active insulation is wind — a stiff breeze blows straight through it and strips the warm air away. That’s the job the Ion 1.1 shell does. Ion 1.1 is a 1.1 oz taffeta nylon with a tight weave that blocks wind and sheds light moisture while still letting the Alpha Direct breathe underneath. Sewn together, the two layers hold the loft and comfort of Alpha Direct behind a shell that keeps its warm microclimate in place — warmth you can actually hang onto on an exposed night. The standard Black Alpha 90 build weighs 13 oz. The White Alpha 120 steps the insulation up to a heftier 120gsm — more warmth, and at 17.4 oz it is honest about what that costs. The Black Alpha Trail 90 swaps in Polartec’s two-way-stretch Alpha Trail fabric behind a dark olive Ion shell instead of black; at 11.5 oz it is the lightest of the three and packs the smallest.
