Sea to Summit Comfort Light ASC Insulated Mat Regular green

Three-season insulated sleeping mat built around Air Sprung Cell technology for backpacking and bike touring.

The Sea to Summit Comfort Light Insulated Mat uses a hybrid-layer Air Sprung Cell construction — a double cell layer at the torso for increased warmth and support, and a single layer at the head and legs to reduce packed bulk. Exkin Platinum fabric reflects radiant heat while Thermolite insulation prevents convective heat loss, combining to deliver an R-value of 3.7 suitable for all but the coldest conditions.
