The Ultralight Mattress features offset air cells that run diagonal to your body’s natural fold lines, making it feel more supportive and noticeably more comfortable than other ultralight mattresses with their vertical or—worse—horizontal baffle structure.
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.
The ultralight inflation sack doubles as waterproof storage for your mattress. Twist, stuff, and cinch it shut!
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.
The tapered shape saves weight and cuts bulk so it's
more compact and lighter in your pack.
The Zenbivy Ultralight Mattress is our lightest and most packable backpacking mattress, starting at just 482 g and rolling down to 16 x 8 cm.
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 provideR5 warmth for EN/ISO-matched thermal performance.
Our embossed 20D Recycled Polyester Taffeta is laminated, not coated, making it stronger and more durable than other ultralight mattress fabrics.
