SEA TO SUMMIT Ultralight XR Inflatable Mattress - Yellow

This new SEA TO SUMMIT Ultralight XR significantly improves on the performance of the previous generation. 14% lighter, 30% thicker, and 53% less bulky when packed, it is incredibly easy to carry while offering a much more generous sleeping surface. Its surface area is 8% larger than many competing models, ensuring a comfortable night's sleep even on restless nights. Its 6.5 cm thickness provides pleasant and stable cushioning that effectively insulates you from uneven ground.

Enhanced insulation thanks to ThermalCore technology

The integration of ThermalCore marks a real breakthrough in thermal performance. A very thin layer of TRM reflects body heat back to the user, improving insulation efficiency andincreasing the R-Value from 2026. Combined with a current R-Value of 3.6 according to ASTM F3340-18, this technology guarantees reliable thermal support during your nights at altitude or in cool conditions. The 151-cell Air Sprung construction naturally conforms to the shape of the body, distributes pressure evenly, and offers a much more comfortable feeling of stability than a conventional inflatable mattress.

A durable and reliable design for demanding expeditions

The Ultralight XR uses a hybrid 30/40D nylon fabric to combine strength and lightness. TPU extrusion lamination improves internal durability, prevents delamination, and incorporates Ultrafresh antimicrobial treatment that has been proven for over ten years. This robust composition extends the mattress's longevity and enables it to withstand many seasons of adventure. Whether you're going on a quick trek, a minimalist expedition, or an impromptu bivouac, it promises reliable comfort and easy setup thanks to its intuitive multifunction valve.
