The Ultralight XR Insulated Air Sleeping Mat by Sea to Summit is an insulated inflatable sleeping mat, an excellent choice for hiking, bikepacking, and long-distance trekking. This tapered model offers remarkable comfort thanks to its structure with 151 air cells that ergonomically adapt to the body, reducing pressure points and ensuring great stability during sleep. Its wider profile is particularly suitable for side sleepers or those who tend to move around a lot at night, while the thickness of 6.5 centimeters allows for easy adjustment of firmness for a customized rest. Durability is ensured by the use of a hybrid nylon fabric of 30 and 40 denier, combined with a liquid-extruded TPU laminate designed to withstand the most intense uses on uneven terrain. Regarding thermal performance, the ThermalCore insulation with TRM reflective film reflects body heat back to the user, offering an R-value of 3.6 while maintaining an extremely compact size. The mat is indeed lightweight and compact, weighing 415 grams and measuring 10 x 19 x 10 centimeters when packed in the regular size, making it easy to store in a backpack. Inflation is quick and requires no effort thanks to the included storage sack that also serves as a practical Airstream pump. Additionally, the high-flow Xpress multifunction valve facilitates inflation, allows for precise pressure adjustment, and ensures rapid deflation when it's time to pack up. The surface is also compatible with the PillowLock system, which keeps the pillow securely in place until morning. This item is available in various sizes to suit every need, starting from the small size weighing only 390 grams, up to the large size at 530 grams designed to accommodate taller body types.
