Features

All-Season Warmth — Only mattresses with an R-value 5 or greater will meet the thermal performance of EN-rated sleeping bags. Most mattresses on the market today that are advertised as “3-season” do not provide the warmth required to match EN-rated bags. The Zenbivy Ultralight Mattress has an R-value 5 for EN-matched performance and all-season warmth: no cold spots.

Quiet mylar insulation — Mylar is a popular lightweight insulation choice, but unlike other ultralight mattresses that are crinkly, loud, and provide insufficient warmth, the Zenbivy Ultralight Mattress has mylar layers that “float” within to quietly reflect heat and provide full R5 warmth for EN/ISO-matched thermal performance.

Tapered design — By trimming off the corners you won’t be sleeping on, the Ultralight Mattress’s tapered shape saves weight and cuts unnecessary bulk so it’s more compact and lighter in your pack.

High-speed valve — The Ultralight Mattress features a brand new high-speed valve. It’s flush and it’s larger so it inflates faster and dumps air more easily. Plus, it’s replaceable and repairable should you ever need it.

Dual-purpose inflation & waterproof storage sack — The Ultralight Mattress includes an inflation sack that doubles as waterproof storage. The waterproof closure is a simple twist-and-cinch, keeping the weight at a mere 1 ounce while ensuring your mattress is dry for camp. Perfectly sized for fast, breathless inflation, just couple the inflation sack to the mattress valve and push air through.

Laminated fabrics — Other ultralight mattresses use coated fabrics. These 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.

  • Supportive offset air-cells

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

  • 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.

  • Inflation Sack I Zenbivy Sleeping Bag Systems

    Waterproof storage

    Includes an ultralight inflation sack that doubles as waterproof storage. Perfectly sized for fast, breathless inflation, just couple the inflation sack to the mattress valve and push air through.

  • Flush, high-speed valve

    The low-profile valve is large for fast inflation and instant dumping of air. Plus, it's replaceable and repairable should you ever need it.

  • Tapered shape

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

  • Flex Air Mattress I Zenbivy Sleeping Bag Systems

    Ultra compact

    Rolling down to just 16 x 8 cm, the Zenbivy Flex™ Air Mattress is ultra-compact and hardly take up any space in your pack.

  • Mylar Layers I Zenbivy Sleeping Bag Systems

    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 provide R5 warmth for EN/ISO-matched thermal performance.

  • 20 D Taffeta I Zenbivy Sleeping Bag Systems

    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.
