Comfort Plus SI Sleeping Pad

Carrying a sleeping pad into the backcountry can be a miserable undertaking, but Sea to Summit has worked hard to change that with the Comfort Plus SI Mat. The mat is three inches thick, so even if you've set up camp on a rock- and root-infested plot, the SI has enough depth to absorb all but the nastiest ground protrusions.

The Comfort Plus comes standard with Sea to Summit's self-inflating valve, so you can get to camp, pop the valve, toss it on the ground, and then go fishing instead of huffing on a valve for the next hour. But if you're like most people, and it's hard to get to sleep on a sleeping pad, the Multi-Function Valve also allows you to fine-tune the SI's firmness, so you can go super-plush at the beach or super firm on desert sandstone.
