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 the unique Delta Coring technique allows the removal of over 40% of foam for a compact do-it-all mat. Built thicker than the original Camp Mat S.I. and using horizontal Delta Coring, the Camp Plus S.I. provides great value, durability and comfort. The 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 Sea to Summit self-inflating mats feature a unique, multi-function reversible single valve, designed specifically for self-inflating mats. No more fighting re-inflation as you roll up your mat! Available in two tapered sizes and two wider, more generously shaped rectangular sizes.
