Sea To Summit Comfort Light Si Mat

“Lightweight all-season comfort and performance”

Twice the thickness of our Ultra Light S.I. mat for no more than 160 grams. Using our Delta Core™ technology, the Comfort Light S.I. is for those of us who are looking for the perfect compromise between comfort and weight in a traditional self-inflating foam mat.
At 5 cm thick, you can be sure of a great nights sleep while an R-value of 2.7 will give you plenty of insulation for 3-season comfort and still leave you with plenty of room in your pack for everything else.

All of our 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!
