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 Light Mattress has an R-value 5+ for EN-matched performance and all-season warmth: no cold spots.

Quiet Comfort — No crinkly chip bag sounds here! With 180g of fully baffled synthetic insulation, the Zenbivy Light Mattress is quiet and built for undisturbed sleep.

Fast Inflation — The included oversized dry sack is sized perfectly for the fastest inflation time and doubles as fully-welded storage to keep the mattress reliably dry on the trail.

Smart Valve — The one-way reversible valve keeps air in while inflating and allows for customizable comfort with its slow-deflation "button”. When it's time to pack up, the entire valve pops out for instant, hassle-free deflation.

Light & Soft — The soft 20D polyester taffeta shell is comfortable enough to sleep on directly while still being durable and lightweight, making it the ideal mattress for backcountry trips.
