Sea To Summit Ultralight XR Insulated

The Sea To Summit Ultralight XR Insulated Air Mat is the ultimate companion for weight-conscious hikers, bikepackers, and fast-moving alpine adventurers. With a respectable 3.6 R-Value, this mat is perfectly tuned for 3-season use, providing reliable warmth from early spring through to late autumn. By being 14% lighter and 16% more insulative than its predecessor, it balances packability with serious performance for any lightweight camping setup. Whether you are tackling a long-distance thru-hike or a weekend summit push, this mat ensures a restful night without weighing down your pack.

Durability meets sustainability in the Ultralight XR’s sophisticated construction. It features a hybrid 30D/40D nylon face fabric that withstands rugged terrain, backed by a liquid-extruded TPU internal laminate to prevent delamination. To ensure long-term hygiene, an Ultrafresh antimicrobial treatment is applied internally. Sea To Summit has also prioritised the environment; the mat uses RCS-certified recycled materials and bluesign® APPROVED fabrics, reducing the ecological footprint of your gear. This robust build offers a proven 10-year field durability record, giving you total confidence in the most remote backcountry environments.

At 6.5cm thick, this next-generation mat utilizes Air Sprung Cell™ technology to mirror the support of a pocket-spring mattress, making it a dream for side sleepers. The ThermalCore insulation system works alongside a reflective TRM layer to trap body heat effectively while maintaining a quiet sleep surface. Convenience is key; the included stuff sack features an integrated Airstream pump for rapid inflation, while the PillowLock™ system keeps your Aeros pillow securely in place. Impressively, the XR packs down 53% smaller than previous versions, fitting effortlessly into any streamlined kit.
