Sea To Summit Ultralight XR Insulated Mat Arrowwood, Small

What Our Gearhead(R) Experts Are Saying:"I've used the Ultralight XR on colder shoulder-season trips, and the warmth-to-weight ratio is impressive. The Air Sprung Cells feel stable compared to baffled mats, and the new valve makes inflation and tweaks way faster. It packs down so small that I bring it on trips where I wouldn't normally take an insulated pad."We turn to the Ultralight XR Insulated Mat when long approaches and cold overnight temps demand warmth without adding weight. Sea to Summit upgraded this mat to be lighter, thicker, and more insulating, giving us a steadier, more supportive feel with a significantly smaller packed volume. With size options tuned for compact kits or more generous layouts, the Ultralight XR adapts smoothly to different backcountry setups without complicating our gear list. Air Sprung Cells contour around our body to reduce pressure points and keep us centered through the night, while the integrated ThermalCore insulation uses a TRM reflective layer to send heat back toward us for a meaningful warmth boost. Durable 30D/40D materials and a TPU laminate maintain long-term reliability, and the improved valve and integrated pump sack make end-of-day setup quick and clean.
