- 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:Â 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:Â 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.
