Unlike fully-calendared ultralight fabrics that are tacky to the touch, Pertex® Quantum uses fine yarns tightly woven together with calendaring on only one side, making it downproof and windproof while maintaining a soft fabric feel. The small ripstop grid adds slight strength and texture.

20D fabrics are much softer than traditional ultralight technical fabrics while being only a fraction heavier. They’re buttery-smooth, comfortable, durable, and worth the minuscule weight penalty. 

A slightly heavier weight than our 20D Taffeta, the 30D Nylon Taffeta is amazingly supple and durable. It's our softest shell.

Our legendary 50D Pongee fabric is pure luxury. It's both durable, soft and—most importantly—has a similar feel to a sheet you would use at home, bringing a familiar kind of comfort to camp.

Goose down is a premium alternative for those that are sensitive to duck down. 900 fill ExpeDRY™ goose down from ALLIED Feather + Down is simply the lightest and the best. ExpeDRY™ is the future of performance and sustainability, using a chemical-free bonding of non-toxic gold particles to the down clusters to aid in evaporation so the down dries faster and stays dry in high humidity conditions.

Premium HyperDRY™ duck down from ALLIED Feather + Down uses a natural wax-based compound to make it water resistant. It is durable, fluorocarbon-free, and RDS (Responsible Down Standard) compliant.

Our premium 650 fill-power down is RDS (Responsible Down Standard) compliant and provides the best bang for your buck.

A great alternative for those that don't want down. Our synthetic quilts use a 1D/3D polyester synthetic blend that is as soft as it gets. It's so soft you'll swear it's down.

All other camp mattresses use tightly woven fabrics that do not stretch. These surfaces transfer weight across the mattress and can feel both stiff and “bouncy”. Our Flex™ mattresses feature an exclusive 4-way stretch fabric that forms instantly to your shape and movement, both minimizing weight transfer and relieving pressure points.

Our embossed 20D Recycled Polyester Taffeta is laminated, not coated, making it stronger and more durable than other ultralight mattress fabrics.

The soft 20D Polyester Taffeta shell is comfortable enough to sleep on directly while still being durable and lightweight, making it ideal for backcountry trips.

Our sturdy 75D Polyester Taffeta fabric gives you long-lasting durability in the outdoors.

Mylar is a popular insulation choice for ultralight camp mattresses, but unlike other ultralight mattresses that are crinkly, loud, and provide insufficient warmth, our mattress's mylar layers “float” within to quietly reflect heat and deliver EN/ISO-matched warmth.

200g of fully-baffled insulation is considered excessive when compared to most air mattresses but actually, it's the minimum required to achieve R4.5+ warmth for EN/ISO-matched performance from your sleeping bag.

Horizontally-cored foam eliminates the cold spots found on most vertically-cored mattresses and delivers R4.5+ warmth for EN/ISO-matched performance.

The non-cored urethane foam insulation in the Base Mattress delivers R4.5+ warmth for EN/ISO-matched performance.
