The Ultralight XR Insulated Air Sleeping Mat by Sea to Summit is an insulating inflatable sleeping mat, an excellent choice for hiking, bikepacking and long-distance trekking. This model with a tapered shape offers remarkable comfort thanks to its construction with 151 air cells that adapt ergonomically to the body, reducing pressure points and ensuring great stability while you sleep. Its wider profile is particularly suited to side sleepers and those who tend to move a lot at night, while the 6.5 centimetre thickness lets you easily adjust the firmness for tailor-made rest. Durability is ensured by the use of a hybrid 30 and 40 denier nylon fabric, combined with a liquid-extruded TPU lamination designed to withstand the most intensive use on rough terrain. As for thermal performance, the ThermalCore insulation with TRM reflective film reflects body heat back towards the user, offering an R-value of 3.6 while keeping the pack size extremely small. The sleeping mat is indeed light and compact, with a weight of 415 grams and packed dimensions of 10 x 19 x 10 centimetres in the Regular size, making it easy to stow in your backpack. Inflation is quick and effortless thanks to the included storage bag, which also serves as a handy Airstream pump. In addition, the high-flow multifunction Xpress valve makes inflation easier, allows precise pressure adjustment and ensures very fast deflation when it is time to set off again. The surface is also compatible with the PillowLock system, which keeps the pillow firmly in place until morning. This item is available in several sizes to suit every need, from the Small size weighing just 390 grams up to the Large size at 530 grams, designed to accommodate taller builds.
