Soft recycled materials: MegaMat features a soft 100percent recycled 4-way stretch tricot polyester surface material that cradles the body and provides next-to-skin comfort. 3D vertical sidewall construction maximizes available sleep area & reduces tapering at the edges similar to your own mattress at home. Customizable comfort; adjust the firmness of your mat by topping off with additional air or opening the inflate valve and pressing gently on the one-way flapper to purge excess air. Self inflating: A one-way low-profile inflate FlatValve allows the mat to self-inflate when opened; insert the included valve pin into the valve opening to speed up air intake. A separate high air flow one-way deflate FlatValve allows for efficient mat deflation. Optional: Use EXPED's combo inflate/deflate Mega Pump accessory (sold separately) to more quickly and easily deflate your mat.
