Sea to Summit Ultralight XR podložka na spanie R - Arrowwood

With an R-Value of 3.1 (ASTM F3340-18), the Sea to Summit Ultralight XR Insulated Mat R delivers reliable three-season warmth in a remarkably light package. Weighing just 480 g, it packs down to 12 x 23 cm, making it an ideal companion for backpacking and fast-and-light adventures.

Overview

The Ultralight XR Insulated Mat R features a single layer of Air Sprung Cells™ for consistent support and comfort. Its tapered rectangular shape reduces weight without sacrificing sleeping area. The 30D/40D nylon fabric is durable yet soft, and the extrusion TPU lamination ensures long-term air retention. THERMOLITE® and Exkin Platinum® insulation work together to reflect body heat and prevent cold spots, while the multi-function high-flow valve allows for rapid inflation and deflation. An integrated Airstream™ Pump Sack simplifies inflation without introducing moisture into the mat. An anti-microbial treatment helps keep the interior fresh.
