The best warmth-to-weight ratio ever in a full rectangular shape.
Best Warmth-to-Weight Ratio Ever: Refined Triangular Core Matrix™ construction and ThermaCapture™ technology deliver a cold-conquering 7.3 R-Value while a Large size weighs just 24 oz (680 g).
Premium Comfort: A 3-inch (7.6 cm) thick profile, horizontal baffled structure and the added sleep surface of the rectangular shape deliver 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.
