Bristlecone MF Sleeping Bag
Western Mountaineering's Bristlecone MF Sleeping Bag is a semi-rectangular bag built for subzero temperatures. Ideal for most winter endeavors, the Bristlecone's 850+ down insulation has the loftiest fill rating, resulting in the highest warmth to weight ratio available on the market. Unlike most water-resistant shells, Western Mountaineering's MicroLite XP fabric offers long-lasting weather protection. The MicroLite XP shell helps the down retain its lofty warmth in moisture-riddled environments.
Western Mountaineering critically thought out the bag's design to the smallest details, making the Bristlecone a long-lasting and very versatile choice. A differential cut places more fabric at the lining to ensure maximum loft inside the bag, and continuous baffles allow you to shift the bag's down towards the top or bottom for more or less warmth. Hook-and-loop tabs let you pull the hood, draft tube, and draft collar farther or closer to you for customized coverage. Extra convenient features include dual zippers on the left or right side, a waterproof stuff sack, and a storage sack with a large volume that helps the bag retain its loft over time.

This isn't a backpacking bag!

Foremost just realize this is not an UL bag so if you try to take it on a UL trip, that's on you!! I bought this for car camping, and dispersed. My slow season is the winter time so I do my camping mostly then. This is a roomy comfortable bag and has served well in 40f- -15 f conditions car camping in Colorado in FEB. If you want basically an extremely lofty goose down comforter that wraps you completely, this is it. It also unzips to a very large size of you need to use it in warmer temps as more of a comforter.

warmest, most comfortable bag
- Familiarity:
- I've put it through the wringer

I have used this bag on every outdoor endeavor that cold may be a factor. It is heavy and large, not well suited for back packing but I have used it in temperatures ranging from 30 degrees F to -10F and the bag has been comfortable at every temperature plus the freedom of movement is tremendous. I highly recommend for people planning on sleeping in the wild in sub freezing temperatures in situations where you are not required to pack the bag on your back...or you accept that most of your pack volume will be taken up by a sleeping bag.
