Therm-a-Rest NeoAir Xtherm NXT MAX Ultralight Camping and Backpacking Sleeping Pad, Neptune, Large

This ultralight, 3-inch-thick air mattress is trusted by alpinists and climbers seeking extra warmth and durability in the backcountry. Reflective ThermaCapture technology traps radiant heat, while triangular core matrix construction minimizes convective heat loss, providing a 7.3 R-value—ideal for extreme conditions. The foam-free NeoAir design weighs just 650g in the regular wide size and rolls up to pack as small as a traditional 1-liter bottle. The 70D ripstop nylon bottom is incredibly durable and puncture-resistant, withstanding the wear and tear of extended expedition use. Equipped with a reliable, heavy-duty WingLock valve. Easy to use, even in freezing conditions, it inflates easily and deflates super fast.
