Sea to Summit Ultralight XR Insulated Air Mat - Regular

Product Information

The Sea to Summit Ultralight XR Insulated Air Mat sets a new benchmark for ultralight sleep systems, delivering more warmth, more comfort, and less weight for fast-and-light adventures. Redesigned from the ground up, this next-generation mat is 14% lighter (weighing 0.48kg), 30% thicker, and 16% more insulative than its predecessor—making it an exceptional choice for backpacking, bikepacking, and high-output missions where every gram matters.

At its core, Air Sprung Cell™ technology uses individually suspended air cells to evenly distribute weight and adapt to your body’s contours. The result is outstanding stability and reduced pressure points, offering noticeably better comfort for side sleepers and restless sleepers alike. Integrated ThermalCore insulation with a reflective TRM layer efficiently reflects body heat back toward you, boosting warmth and R-value performance without adding bulk.

Built for real-world use, the Ultralight XR features a durable hybrid 30D/40D face fabric, a robust TPU internal laminate, and Ultrafresh® antimicrobial treatment for long-term hygiene and reliability. Sustainability is equally prioritized, with RCS-certified recycled materials and bluesign® APPROVED fabrics that reduce water, chemical, and energy use by approximately 30%.

Exceptionally packable—compressing to 53% smaller than previous models—this mat disappears into your pack but delivers dependable warmth and comfort wherever you stop for the night. From thru-hikes to alpine objectives, the Ultralight XR ensures quiet, supportive, and restorative sleep in demanding environments.
