    No need to compromise.

    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. The 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 to repel any wayward drips and drops. A full-length pad keeps your sleeping pad from shifting throughout the night, and it maximizes thermal efficiency by protecting you from the frozen ground. Big Agnes also included an integrated pillow pocket to keep your camp pillow in place, and 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.

    My Favorite Bag

    • Familiarity: I've used it several times

    I was a little weirded out by Big Agnes's sleep system before I used it. This is one of two of their bags that I use with their sleep system. I LOVE this bag.

    The bag is roomy enough to move around, side sleep, etc. and the insulation wraps the sides of the pad. I move around a lot when I sleep - which can be annoying when camping but the sleep system keeps me on my pad and I can spread my feet off the sides of the pad when I'm feeling extra wiggly.

    It has a good hood and collar. Comfy and not claustrophobic. You can side sleep with things tight enough to be warm on colder nights without feeling like you're going to asphyxiate.

    The bag packs down quite small but so far it's maintaining it's loft well. Many people don't care about looks but it's a great-looking bag as well.

    The shoulder girth numbers here seem a little larger than normal for Big Agnes: are these external dimensions or internal? E.g. what is the max shoulder size the regular bag can accommodate without compressing the insulation overly much?

    Hey James!

    The measurements are internal! So Honestly your Shoulder circumference should be the same number or less if possible. Not only would the insulation be a bit flattened It would be a bit uncomfortable!
