Sea To Summit UltraLight

The new Ultralight S.I. Mat self-inflating mattress is made of Delta Core-V™ cut-out foam.This new technology uses the Delta Coring vertical method, making it lightweight, so that the total weight of the mattress is reduced by 20%. In areas where heat is needed: shoulders, hips, feet, the structure has been designed so that the holes are as small as possible to provide more heat. In other areas, the holes are larger, in order to reduce the total weight and volume of the mattress.The mattress has non-slip parts on the top and base to hold your sleeping bag and mattress in place. This mattress also features a high-flow multi-functional valve to allow one-way inflation and a more precise adjustment for comfort. The Ultralight S.I. Mat is a self-inflating, compact and lightweight mattress.
