Description

The Ultra Light XR PRO Insulated Arrowwood brand's mattress Sea to Summit is a high-performance inflatable mattress designed to offer sports enthusiasts and hikers a sleeping solution that combines extreme lightness, compactness and thermal comfort for adventures in the great outdoors.

This model is lighter and less bulky than its predecessor, while still offering a generous Thickness of 6.5 cm. Its structure is based on celltechnology Air Sprung, consisting of 151 individual chambers that precisely follow the contours of the body to minimise pressure points and ensure superior stability compared to conventional inflatable mats.

With a sleeping surface that is 8% larger than the market average, this mattress ensures optimal rest without compromising on space in your backpack. Technically, it incorporates technology ThermalCore that reflects body heat thanks to a thin layer of TRM, thereby achieving R-Value de 3,6. Durability is ensured by a resistant fabric with a proven Ultra-Freshantimicrobial treatment for increased longevity. To facilitate its use in the field, it is equipped with a valve XPRESS and comes with an integrated Airstream inflation bag and a self-adhesive repair kit. Finally, the included Pillow Lock™ system allows you to securely attach your pillow to the mattress to prevent it from slipping during the night.
