The Camp Plus S.I. is designed to provide maximum comfort for people chasing a versatile all around sleeping mat.

Combining robust and durable 75D fabrics with our unique Delta Coring technique allows us to remove over 40% of foam for a compact do-it-all mat. Built thicker than our original Camp Mat S.I. and using horizontal Delta Coring, the Camp Plus S.I. provides great value, durability and comfort.

Our use of a 75D polyester makes for a tougher, more abrasion resistant base, while at 7.5cm thick, the Camp Plus S.I. provides ample cushioning for even the boniest of hips. The high 4.3 R-value also means you can use it all year round.

All our self-inflating mats feature our unique, multifunction reversible single valve, designed specifically for self-inflating mats. No more fighting re-inflation as you roll up your mat!
