Fabrics: Quilts & Sheets

  • 10D Pertex™ Quantum

    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 only being a fraction heavier.

    20D Nylon Taffeta

    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. 

  • 30D Nylon Taffeta

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

  • 50D Polyester Pongee

    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.

What is denier?

Fabric denier (D) is a unit of measurement used to describe the thickness and weight of individual fibers or threads in a textile.

Higher denier fabrics use thicker threads, making them more durable, but heavier. Lower denier fabrics use finer threads, resulting in a lighter weight but more delicate material.

Understanding denier helps you choose fabrics suited to specific needs, balancing durability against weight and feel.

Fills: Quilts & Sheets

  • ExpeDRY™ Goose Down (900fp)

    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.

  • HyperDRY™ Duck Down (700fp, 800fp)

    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.

  • Duck Down (650fp)

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

  • 1D/3D XD Synthetic

    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.

Fill-Power Explained

Down quality is measured by its fill-power, which in simple terms is a measure of the down cluster’s size. Larger clusters trap more air and are both warmer and lighter compared to lower quality down. The larger the down cluster, the higher the fill-power rating. 

Fill-power represents how many cubic inches one ounce of down will occupy. If one ounce of down takes up 700 cubic inches of space, it is rated as 700 fill-power down. This means that less will be needed to achieve the same warmth as a 600 fill-power or lower down.

There are 3 different grades of down often used: 550 to 650 fill-power (high quality downs), 650 to 750 fill-power (performance downs), and 750 to 900 fill-power (premium downs—the lightest, warmest, and most expensive).

Fabrics: Mattresses

  • Flex™ 4-Way Stretch Knit

    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.

  • Embossed 20D Recycled Polyester Taffeta

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

  • 20D Polyester Taffeta

    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.

  • 75D Polyester Taffeta

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

Insulations: Mattresses

  • Mylar Foil

    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.

  • 3D XD Synthetic

    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.

  • Zenbivy Flex Mattress Mattresses ZENBIVY

    Horizontally-Cored Urethane Foam

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

  • Urethane Foam

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

What is R-value?

R-value is a measure to quantify insulation's ability to resist heat. In other words, it's a measure of thermal resistance. The higher the R-value, the greater the thermal resistance and the better it will keep you insulated from the ground below.
