Ultralight XR Insulated Air Sleeping Mat

The Sea to Summit Ultralight XR Insulated Air Mat delivers advanced warmth, comfort, and packability in a true ultralight design. This next-generation insulated sleeping mat is 14% lighter, 30% thicker, and 16% more insulative than before—making it ideal for backpacking, bikepacking, and fast-moving adventures. Featuring Air Sprung Cell™ technology, the Ultralight XR conforms to your body for even support and fewer pressure points, providing superior comfort for side sleepers and active sleepers alike.

The ThermalCore insulation system reflects body heat back toward the sleeper for reliable performance in cold conditions, while a durable 30/40D face fabric and TPU internal laminate ensure proven field reliability. Built with RCS-certified recycled materials and bluesign® APPROVED fabrics, the Ultralight XR offers exceptional comfort with a lower environmental footprint. Whether you’re tackling a thru-hike or chasing alpine summits, this sleeping mat guarantees a warm, quiet, and restful night’s sleep—anywhere you roll it out.
