Camp Si Mat - Large

“Durable and comfortable all-rounder”

The Camp Mat S.I. is the workhorse of our Self Inflating Sleeping Mat range. Our use of a 75D Polyester makes for a tougher, more abrasion resistant base, while at 3.8cm thick, the Camp Mat is thick enough to keep even the boniest of hips from pushing through to the ground. The high R-value also means its great to use in all seasons.

Whether your’re looking at purchasing for personal or institutional use, this is definitely a product worthy of the Sea to Summit brand name.

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!
