A warm, plush option for backpacking or camping, the Sea to Summit Comfort Plus SI Mat utilizes unique die-cutting to achieve a 4.1 R-Value and provide a 3”-thick sleeping base.
The tapered, 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 30D stretch-knit top fabric feels cozy next to skin and the 30D plain-weave base fabric bolsters durability.
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 3”) and Large (78” x 25” x 3”) size options, the Sea to Summit Comfort Plus SI Mat includes a custom-fit 30D stuff sack.

Real Customer Reviews
- Great with some quirks.
R value is solid
Not to heavy
Dislikes: Bulky (naturally for a si pad)
Very difficult to put back into stuff sack
- Nice Mat!
Likes: Good for a side sleeper. It's quiet, with no crinkling sounds. Well insulated. Comfortable.
Compression sack: Set valve to deflate mode. Fold mattress in half width-wise, use your body to smoosh the air out. Then fold it in half, length-wise, and use your body to smoosh more air out. Unfold. Fold in half width-wise, and roll it up. Cap the valve. Done. It's not bad, really.
Dislikes: I don't care for the color. It didn't come with a repair kit, I'm not sure if it was supposed to or not.
- Great Product
Likes: Fits to my sleeping bag perfectly, very comfortable, minimal noise, easy to inflate
Dislikes: Nearly impossible to make small enough to fit back into its original bag
Likes: This is probably the most comfortable sleeping pad you can get for backpacking. I'm a pretty lean packer, but I always make sure I have good sleeping gear, well worth it.
Dislikes: The sack they give you is tiny, almost impossible to get back into once it is no longer factory rolled. Not the biggest drawback, just gotta get a different one.
