The full-rectangular XTherm NXT MAX delivers a 7.3 R-value while weighing just 24 oz (680 g) in the Large size thanks to state-of-the-art Triangular Core Matrix construction and ThermaCapture technology. The best warmth-to-weight ratio of any rectangle sleeping pad ever made, to put it another way. The XTherm NXT MAX solidifies the reputation of being the preferred rectangle sleeping pad for alpinists, mountaineers, and severe cold excursions since it is warmer, lighter, and thicker than the previous model. All-night comfort and support are available because to the 3-inch thickness, horizontal baffles, and more sleep surface provided by the rectangular form, while the 70D nylon on the bottom assures that the XTherm NXT will withstand repeated expedition use. The WingLock Valve not only enables quick inflation and deflation but is also simple to operate even when wearing gloves in arctic conditions. There is no better sleeping pad than the XTherm NXT MAX when you absolutely must be warm no matter the weather, want plenty of sleep surface, but pack space is at a premium.
