With a comfort temperature rating of -30°C you can camp out in alpine conditions and mild polar conditions. Its weight is 1570 grams, which is low considering the low comfort temperature.
It is made using a Pertex Quantum Pro (formerly Pertex Endurance) ripstop shell filled with 900g of 850 FP Polish Goose down. Superior Brick construction eliminates cold spots and increases warmth, enabling a comfortable night’s sleep in extremely low temperatures.
