Thermarest - NeoAir XTherm NXT Sleeping Pad

A 7.3 R-value in a pad that weighs 439g is a number worth stopping on. The Therm-a-Rest NeoAir XTherm NXT holds the best warmth-to-weight ratio of any sleeping pad ever made, and it's the reason this pad has become the default choice for alpinists, mountaineers, and anyone pushing into serious cold.

The same Triangular Core Matrix construction and ThermaCapture technology that powers the MAX version is at work here, reflecting radiated body heat back toward you and cutting heat loss through the pad to deliver that 7.3 R-value. At 3 inches (7.6 cm) thick with horizontal baffles, it provides genuine overnight comfort and support, not just insulation. The mummy-shaped profile keeps the packed size and weight to a minimum compared to the rectangular MAX, making it the go-to for expeditions where every gram in the pack is accounted for.

Bottom fabric is 70D nylon, chosen specifically to handle the abrasion and wear of extended backcountry use on rough surfaces. The 30D ripstop nylon on top keeps things light without sacrificing durability. The WingLock valve inflates fast, deflates quickly, and crucially, operates easily with gloves on when temperatures make bare hands a non-starter. Available in three sizes to fit your sleep system properly.
