Sea to Summit Comfort Light ASC Insulated Mat Large

Hybrid Air Sprung Cell construction with dual-layer insulation for backpackers who need reliable warmth without excess bulk.

The Sea to Summit Comfort Light Insulated Mat uses a hybrid Air Sprung Cell matrix to deliver stable, comfortable sleep on the ground. A double cell layer in the torso zone maximises insulation where it matters most, while a single layer at the head and legs reduces overall weight. Rated R-Value 3.7, it covers three-season conditions and suits backpacking and bike touring.
