Weighing in at just over a half-pound, the insulted Therm-a-Rest NeoAir UberLite Minimalist Backpacking Air Mattress is a highly packable sleeping pad perfect for ultralight camping and backpacking that demands a minimalist pack. Therm-a-Rest’s proprietary construction provides the critical warmth needed in the backcountry offering an R-value of 2.0 (R-value measures the material’s ability to insulate; the higher the R-value, the warmer the sleeping pad). Boasting 2.5-inches of luxurious NeoAir comfort, the minimal UberLite makes a big impact during nights in the backcountry. The tapered design reduces weight without compromising warmth, and the unique fabrics used for this pad meet strict durability standards that backpackers, alpinists and thru-hikers can depend on. This camping air mattress inflates in less than two minutes by blowing into the valve, and packs to the size smaller than a one-liter water bottle. Available in 3 sizes: Small measures 47x20x2.5 inches inflated, packs to 6x3.3 inches, and weighs 6 ounces; Regular measures 72x20x2.5 inches inflated, packs to 6x3.5 inches, and weighs 8.8 ounces; Large measures 77x25x2.5 inflated, packs to 7.5x3.7 inches, and weighs 12 ounces. Stuff sack and repair kit included. Manufacturer’s limited lifetime warranty. Made in the USA.
