An excellent balance of price and performance, the Sea to Summit Camp SI Mat delivers self-inflating comfort for 3-season backpacking and camping.

The tapered pad uses Delta Core Technology to create supportive cushioning, deliver consistent warmth, and make inflation efficient. Body-mapped die-cutting in the open-cell foam core adds structural support in the shoulders, the hips, and at your feet while cutting down on bulk in areas of the pad where less support is needed. This design also helps to cut down on weight and allow the mattress to roll up more compactly when not in use. The 75D polyester face fabric is highly durable. The pad’s 4.0 R-value makes it suitable for 3-season use.

A stand-out feature on Sea to Summit pads is the low-profile multi-function valve. A one-way design allows for fuss-free inflation and 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 your choice of Regular (72” x 20” x 1.5”) and Large (78” x 25” x 1.5”) size options, the Sea to Summit Camp SI Mat includes a custom-fit 30D stuff sack.

Great pad for the price
Reviewed by Nathan V. - December 15, 2018

Likes: Self inflating like described. Very light and compacts to a pack-able unbulky size to fit in any pack.

Dislikes: My own fault I should've got the larger mat but I was compensating weight. Just wish the pad was a bit bigger.

large but reliable
Reviewed by Andrew K. - July 21, 2018

Likes: the foam is more reassuring than only have air and as a layer of insulation. the material is the thickest, most durable of sleeping mats: 75D polyester. it is very comfortable.

Dislikes: squeezing air out in the morning is a hassle. air mats may be quicker and easier.
