Sea to Summit Comfort Delux Self Inflating Large Wide

Ten centimetres of Delta Core foam and an R-value of 6.5 — built for cold-weather comfort at base camp or on the road.

The Sea to Summit Comfort Deluxe Self-Inflating Mat is designed for campers and overlanders who prioritise warmth and sleeping comfort over packability. Delta Core foam construction reduces weight and packed volume relative to the mat's thickness, while a 30D stretch knit upper regulates surface feel across temperatures. A flip-over multi-function valve handles inflation, deflation, and pressure fine-tuning without air re-entering the mat during packing.
