Sea To Summit Ultralight ACS Insulated Mat - Large

Lightweight Comfort Without Compromise

For adventurers who demand comfort, durability, insulation, and ease of use in a lightweight sleeping pad, the Ultralight Insulated Air Sleeping Mat is the perfect choice.

Its Air Sprung Cell design provides exceptional stability and support, while advanced lamination and weld quality set a new benchmark for reliability.

• 3.1 R-Value is sufficient for late spring to early fall use.
• Exkin Platinum insulation reflects your radiant heat back to you, while Thermolite insulation prevents convective heat loss.
• Lighter, quieter and durable 30D/40D face fabric with Sea to Summit’s liquid-extruded lamination is extremely reliable.
• Quick and easy inflation, deflation and adjustment is made possible by our multi-function valve and supplied Airstream Pump/stuff sack.
• Anti-microbial treatment added to the TPU lamination formula prevents internal mold growth.
• PillowLock system prevents your Sea to Summit Aeros Pillow from slipping.
• Comes with a stuff sack which doubles as a pump, a repair kit with six self-adhesive patches and a spare valve insert.
