Product Overview

The finest sleeping bag ever created

The 0° Super Down Sleeping Bag has the heaviest fill weight of our sleeping bag line, and is packed full of down to keep you warm when conditions are at their worst. Utilizing 850+ fill power European goose down with Toray’s water resistant coating, and a unique vertical baffle design, we have created a sleeping bag line that is incredibly warm, lightweight, and weather resistant. The vertical baffle design allows heat to transfer from head to toe freely. Integrated flow gates throughout each baffle keep the down from shifting and creating cold spots, minimizing heat loss, and allowing you to utilize your bag in a wider range of temperatures. A full length zipper and double sliders, allows added ventilation at the footbox.

Quixdown® by Toray

Waterproof Warmth 

Down has the highest warmth-to-weight ratio of any insulation material. The only drawback is that once wet, down stops being effective. Not anymore. Through nanotechnology, Toray Industries has created a water repellent finish for down feathers that makes each down cluster essentially waterproof. Quixdown® stays dry to keep you warmer with less weight and bulk.
