Designed for Maximum Comfort in Minimal Weight

Advanced Air Sprung Cell™ Technology

Unlike traditional sleeping mats with horizontal or vertical baffles, Sea to Summit’s Air Sprung Cells™ are independent air chambers that conform to your body’s shape, providing better weight distribution and eliminating pressure points. The result? A softer, more supportive feel that promotes deeper sleep.

The single-layer construction ensures the lightest and most packable insulated mat without compromising comfort, making it perfect for three-season adventures.

Stay Warmer with Exkin® Platinum & THERMOLITE® Insulation

Cold nights can ruin a great adventure, which is why the Ultralight Insulated Sleeping Mat incorporates two layers of thermal technology:

✅ Exkin® Platinum – A lightweight, noise-free, and heat-reflective layer that bounces your body heat back to you to reduce radiant heat loss.
✅ THERMOLITE® Insulation – Traps warm air inside the Air Sprung Cells™, creating an effective barrier between you and the cold ground.

Together, these technologies provide a high warmth-to-weight ratio, ensuring you stay warm without extra bulk.

Effortless Inflation & Deflation with Multi-Function Valve

The patent-pending multi-function valve makes setting up and packing down fast and hassle-free:

🔹 One-way inflation valve – Prevents air loss while inflating, so you don’t have to rush to seal it
🔹 Rapid deflation port – Instantly releases air for quick pack-up
🔹 Fine-tune adjustment button – Lets you control firmness for personalized comfort

Plus, with the Airstream™ Pump Sack integrated into the stuff sack, inflating your mat is effortless and moisture-free—no need to waste lung power!
