Therm a Rest NeoAir XTherm NXT Ultralight Camping and Backpacking Sleeping Pad, Neptune, Large

Best Warmth-to-Weight Ratio Ever: Refined Triangular Core Matrix construction and ThermaCapture tech delivers a cold-conquering 7.4 R-Value. Premium Comfort: A 3-inch (7.6 cm) thick profile and horizontal baffled structure delivers premium backcountry comfort while keeping the weight to a minimum. Ultralight Durability: 70D ripstop nylon on the bottom withstands the wear and tear of extended expedition use, while 30D ripstop nylon on top keeps it light and packable. WingLock Valve: With a large orifice and “wings” that toggle one-way flow, the WingLock delivers smooth and fast inflation and deflation without giving up the ability to easily purge air while you lay on it for comfort micro-adjustments—even with gloves on. Pump sack, stuff sack and field repair kit included.
