We’re Proud To Introduce the New Zenbivy Mattresses!

  • Flex™ Air Mattress

    The revolutionary new Flex™ Air Mattress is the only ultralight air mattress to feature a 4-way stretch top. In combination with the supportive diagonal baffle pattern, there's truly a "wow" moment when you lay on it—an extraordinary comfort difference you have to sleep to believe. Starting at 1 lb 4 oz and delivering EN/ISO-matched warmth, the Flex™ Air Mattress is ultralight backpacking luxury.

  • Ultralight Mattress

    The uncommonly supportive Ultralight Mattress features the same diagonal baffle structure as our Flex™ Air Mattress but swaps the stretch knit top for an ultralight 20D honeycomb embossed Recycled Polyester Taffeta, bringing the weight down to just 1 lb 1 oz. Two layers of featherlight mylar insulation deliver EN/ISO-matched warmth.

Flex™ Air Mattress

Revolutionary, Exclusive 4-Way Stretch Top

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 new Flex™ Air Mattress features an exclusive 4-way stretch fabric that forms instantly to your shape and movement, both minimizing weight transfer and relieving pressure points.

  • Supportive Offset Air Cells

    The offset air cells create a diagonal baffle pattern that causes the mattress to twist against your body’s natural fold lines rather than collapse into them like horizontal and vertical baffles, resulting in a more supportive mattress.

  • Flush, High-Speed Valve

    The low-profile valve is large for fast inflation and instant dumping of air, and the slow-deflation "button" allows for customizable comfort. Plus, the whole valve is replaceable and repairable should you ever need it.

  • Included Inflation Sack

    Bigger does not mean faster! An inflation sack that's too big is just more material to wrestle. Our slightly oversized ultralight inflation sack (1.0 oz) is optimized for the fastest inflation time. It's quick and easy to use, just couple the inflation sack to the mattress valve and push air through.

  • Waterproof Storage

    The ultralight inflation sack doubles as waterproof storage for your mattress. Twist, stuff, and cinch it shut!

  • Tapered Shape

    The tapered shape saves weight and cuts bulk so it’s more compact and lighter in your pack.

  • Ultra-Compact

    Rolling down to just 6.5" x 3", the new Zenbivy mattresses are ultra-compact and hardly take up any space in your pack.

  • Mylar Layers

    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 R4.5+ for EN/ISO-matched performance.

  • 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.

  • Laminated Fabrics

    Other mattresses use coated fabrics which can break down over time, making them less durable and, therefore, less reliable. We laminate a PU (polyurethane) membrane to our fabrics. This separate membrane does not break down and the welds are stronger, resulting in a more durable and long-lasting mattress.
