Big Agnes Blackburn UL Sleeping Bag: 0F Down

Minimizing weight and space on gear-intensive trips is important, but so is not getting frostbite in the middle of the night. Take care of both problems with the Big Agnes Blackburn UL 0 Degree Down Sleeping Bag. Whether you're backpacking through high-altitude ranges in summer or going on a ski touring hut trip, the Blackburn UL is the ideal way to stay warm without tacking on too much extra bulk.

Down insulation keeps you comfortable through below-freezing temperatures while making the bag lightweight and highly compressible. This down is treated with DownTek to protect it from loft-compromising moisture. Just to be safe, the soft and smooth ripstop fabric is treated with a DWR coating as well to repel any wayward drips and drops. A full-length pad sleeve keeps your sleeping pad from shifting throughout the night, and an integrated pillow pocket keeps your camp pillow in place. You can even stuff it with spare layers when you really want to go minimalist. The Free Range hood and No-Draft collar, wedge, and zipper prevent cold air from slipping in through the cracks. Plus, the vaulted, tapered footbox gives your toes room to wiggle without creating large cold air pockets.
