Thermarest NeoAir XTherm NXT

The Thermarest NeoAir XTherm NXT holds the respectable title of 'the best warmth-to-weight ratio of any sleeping pad ever created'. With an R-Value of 7.3 and a weight of just 439 g (Regular), it's one of if not the top air sleeping mats for alpinists, mountaineers, and extreme conditions. 

Features:

• Best Warmth-to-Weight Ratio Ever: Refined Triangular Core Matrix™ construction and ThermaCapture™ technology deliver a cold-conquering 7.3 R-Value while a Regular size weighs just 15.5 oz (439 g).
• 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 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: Delivers fast one-way inflation and rapid deflation without giving up the ability to easily purge air while you lay on it for comfort micro-adjustments—even with gloves on.
• Multiple Sizes: 3 size options allow you to get the XTherm NXT that is perfect for your sleep system.
• Pump sack, stuff sack and field repair kit included.
