The Comfort Light™ Self Inflating Mat is an excellent lightweight, backpacking option that offers superb comfort at a low weight and small packed size.

The Delta Core™ technology removes 40% of bulk and weight from the 2" thick foam to keep your nights comfortable.

The multi-function valve is a low profile, high volume valve that flips over to allow fast deflation without fighting re-inflation as you go.

The Comfort Light Self-Inflating Mat is a real alternative to air mats for many backpackers and for campers who like to sleep comfortably.

R-Value of 3.1 - sufficient warmth for Spring to Fall camping. 

2" thick foam for a really comfortable night sleep

Flip-over multi-function valve for fast and easy inflation, deflation and fine tuning of air pressure

Woven 30D polyester face fabric chosen for its light weight and strength

Silicone print prevents your sleeping bag from slipping on the mat, or the mat slipping on the tent floor

Utilizes Delta Core technology, which significantly reduces weight and packed volume

Supplied Pillow Lock patches keep your Sea to Summit pillow firmly attached to the mat

Multi Function valve prevents re-inflation as you pack up 



Different from other lightweight self-inflating mats?

Yes. The Delta Core technology reduces the weight and packed volume by 40% - and the Comfort Light is a full 2" thick (compared similarly-priced 1.5"-thick self-inflating mats.)


Insulated well enough for three-season temperatures?

Yes. The Comfort Light SI Mat has a tested R-Value of 3.1 - suitable for use from Spring to Fall.


Small enough when packed to use for backpacking?

Possibly. The packed size of 5.75"x10" (Regular) will fit into most conventional backpacker's 60+ Liter packs. Performance-oriented backpackers may prefer an air mat - see above.
