Sea To Summit Ultralight Light SI Mattress XS

Light and packable for multi-stage racing!

The Ultra light S.I. Sleeping Mat is for ultra-light hikers and runners who can’t go past the tried and true self-inflating foam mats. The 2.6 R-value provides the insulation needed through the shoulder seasons while the memory foam means you don’t have to exert yourself inflating your mat at the end of the day. The only mat in the S.I. range to come in an extra-small size, it’s easily fits into your ultra-light pack.

All of Sea to Summit S.I. mats use the first ever, multi-function single valve designed specifically for self-inflating mats. No more fighting re-inflation as you try to roll up your mat!

• Self inflating in just a few breaths

• Anti-slip print on base of mat, helps hold your mat in place when camping on sloping ground is unavoidable
