Features
- Polarguard Delta insulation is lightweight, compressible and continues to insulate even when wet - making this bag perfect for wet climates
- The Quantum Expander provides an additional 8 inches of girth - allowing for extra layering space in cold temperatures, or extra room when it is warmer
- Improved shape in the hood brings the sides of the hood in close to the neck and face, reducing the need to cinch the hood tight to keep warm
- The comfort foot box is shaped to allow feet to rest naturally and designed to preserve the loft - keeping your feet warmer
- Shingled construction overlaps Polarguard Delta insulation sheets to maximize loft and eliminate cold spots
- Polyester taffeta lining doesn’t have that "ice-cold" feeling that nylon liners have when initially slipping into the bag
- Double draft tubes prevent the cold from encroaching and an ergonomic draft collar seals in heat below the shoulders
- Cotton storage bag and stuff sack included
