S2S S/Mat UltraLight Self Inflating Mat Large

Sea to Summit Ultralight Self Inflating Mat

The Ultralight Self-Inflating Sleeping Mat is built for adventurers who value every gram and still want a good night’s sleep. Designed for minimalists, this mat combines smart comfort with low weight and pack volume.

Thanks to Delta Core-V™ technology, it reduces bulk by removing foam in strategic areas while maintaining support under key pressure zones. The embossed silicone grip print keeps your sleeping bag securely in place through the night, even on uneven ground.

When it’s time to pack, the multi-function valve allows fast deflation without air sneaking back in. Perfect for lightweight backpacking, bikepacking, and thru-hikes where space and weight are at a premium.
