Therm-a-Rest NeoAir XTherm NXT Ultralight Sleeping Pad – Regular, Neptune

Ultralight warmth for serious backcountry sleepers

The NeoAir XTherm NXT is crafted for alpinists, mountaineers, and cold-weather expeditions seeking a balance between weight and comfort. With a foam-free design, it packs as small as a conventional bottle yet outperforms in warmth-to-weight terms.

How it works

Core comfort comes from the Triangular Core Matrix and Reflective ThermaCapture technology. These features work together to minimize convective heat loss and trap radiant heat, delivering a measured 7.3 R-value in the Regular size. The result is a pad that supports you through long alpine nights while keeping weight down (15.5 oz / 440 g).

• 3-inch thickness provides altitude-friendly support with all-night stability
• Heat-trapping design aims to boost warmth without added bulk
• Foam-free NeoAir construction emphasizes packability and quick setup
• Durable 70D ripstop nylon bottom withstands rugged use in the field
• WingLock valve supports easy inflation and fast deflation even in cold conditions

Who is it for?

Ideal for ultralight backpackers, mountaineering teams, and winter campers who value warmth, compact packing, and reliable performance. Regular size measures 20 x 72 in (51 x 183 cm), and the pad can be found in Regular, Regular Wide, and Large variants to match different sleeping styles.

• Lightweight option at 15.5 oz (440 g) in Regular
• Compact roll-up makes it easy to stash in a backpack or bivy bag
• Protected by Therm-a-Rest's limited lifetime warranty

Included with the pad are a pump sack, a stuff sack, and a patch kit, so you can set up camp quickly and address minor punctures on the go. Built in the USA with high-quality materials, this pad aims to deliver long-term reliability in diverse backcountry environments.
