Therm-a-Rest NeoAir XTherm NXT Self-Inflating mattress-Large-Neptune
The Therm-a-Rest NeoAir XTherm NXT Large is an ultralight air-filled camping mat for alpinists, mountaineers, and extreme cold expeditions. The Large is the longest in the NeoAir XTherm NXT series, suitable for those up to 196cm/6ft5in. At 7.6cm thick, all-night comfort and support are a given, plus you can adjust inflation levels for personalised firmness. The NeoAir XTherm NXT Large boasts a fantastic warmth-to-weight ratio, achieving a cold-conquering 7.3 R-value while weighing just 567g. Its Core Matrix construction features individual triangular baffles that limit the free flow of air, slowing convective heat loss and creating a stable sleep surface. The ThermaCapture technology employs a featherweight reflective internal film that redirects heat back to your body. The glove-friendly WingLock Valve offers one-way inflation and rapid deflation for fast and efficient packing. You can use the pump sack for a breath-free inflation option, which stops condensation build-up. Supplied with instant repair patches, you'll be prepared for anything while you’re on the move.
