A compact and efficient ultralight mat that delivers strong comfort for its weight and pack size
Sea to Summit says:
Lighter. More Packable. Proven Durability.
151 individual Air Sprung Cells conform around your body reducing pressure points and provide far greater stability than traditional baffled air mats.
Hybrid 30/40D fabric and an extruded TPU internal laminate with Ultrafresh Antimicrobial treatment has a 10-year proven track record
Light and effective ThermalCore insulation uses a TRM layer to reflect body heat back to the sleeper, resulting in a 16% R-Value increase for 2026.
Our Verdict
The Sea to Summit Ultralight XR Insulated Mat - Regular balances low weight with solid three-season performance, weighing 540g and offering an R-value of 3.6. It packs down small and fits easily into a pack, making it a strong option for weight-conscious setups.
At 6.5cm thick, it provides a supportive feel without excess bulk. The air chambers distribute weight evenly across the mat, reducing pressure points and creating a stable sleeping platform. This works particularly well for those who sleep on their side, helping maintain comfort through the night. Warmth is well judged for three-season use. The integrated pump sack is quick and efficient, making setup straightforward while keeping moisture out of the mat. The valve system is simple to use and allows easy adjustment of firmness.
