Flex Mattress

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 Flex Mattress has an R-value of 5 for EN-matched performance and all-season warmth: no cold spots!

Silent Comfort — Fall asleep and stay asleep. The Flex Mattress's horizontally-cored foam insulation makes for a silent night at camp. The 4-way stretch fabric allows this mattress to “flex” with your shape and movement, so the top feels softer and more supportive than other camp mattresses - even at firm air pressures.

Fast Inflation — The included oversized Inflation Dry Sack is sized perfectly for the fastest inflation time and doubles as fully-welded storage to keep the mattress reliably dry when packed.

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. Then pop the "deflation" valve side back in and the air stays out as you continue to roll.

R-value: 5
(Note: only mattresses with an R-value of 5 or greater will deliver full temperature rating performance from EN-rated sleeping bags)
