For anyone venturing outside in all 4 seasons, a properly warm sleeping pad is essential and even better if it delivers comfort too. The Sea to Summit Camp Plus SI Mat properly checks both of those boxes with a warm 4.3 R-Value and 3 inches of plush foam to settle into.
The self-inflating pad uses Delta Core Technology to create supportive cushioning, deliver consistent warmth, and make inflation efficient. Triangular cutaways within the open-cell foam core add structural support while cutting down on bulk and enabling the mattress to roll up more compactly when not in use. The super tough 75D polyester shell fabric shrugs off abrasion and holds up incredibly well to repeated use.
30D stretch-knit top fabric feels cozy next to skin and the 30D plain-weave base fabric bolsters durability.
The self-inflating design allows you to open the valve which automatically draws air into the open cell foam core. Given proper time to inflate, the pad just needs another puff or two of air to reach maximum inflation. The pad's low-profile multi-function valve has a one-way design that allows for fuss-free inflation. An internal button lets you make micro adjustments to firmness. A larger port beneath the top portion of the valve makes deflation quick and easy. Additionally, by setting flush to the surface of the pad, the valve also cuts down on potential warranty issues.
Available in a variety of sizes and shapes (standard and Rectangular), the Sea to Summit Camp Plus SI Mat includes a small repair kit with self-adhesive patches and a spare one-way valve flap
