When things get real chilly the halo collar and baffled draft tube help ensure no errant gusts of cold wind find their way to you. An internal storage pocket lets you keep a headlamp or other necessities close at hand.

    Woke up Warm

    • Familiarity: I've used it several times

    This bag lives up to its rating. When I woke up in the middle of the night to remove layers during a snowstorm I was sold. It's light, compresses well and is comfortable to sleep in. My only long term concern is the durability of the face fabric. But as with any lightweight fabric caution and care are paramount. I'm 6'2" 175 and I went with the long it perfectly balances room for comfort and minimal dead space.

    • Familiarity: I've put it through the wringer

    The Brooks-Range Drift 15 sleeping bag is simply the best ultralight mummy sleeping bag anyone could ever want. I have owned the Drift 15 for about a year now and have used it on the order of 8 nights here in the Colorado Front Range, and I honestly can't complain about anything. For starters, the Drift 15 is, as the name implies, a bag rated for "15ish" degree temperatures. I can absolutely confirm this is not an inflated rating. I've used it into the 20s several times and stayed toasty warm, so I would be comfortable using the bag probably even past 15 degrees. The Drift 15 has 22.5 ounces of 850 fill down, which is more than literally every other bag in the same category; however, the Drift 15 still remains to be just as light as the other bags. The 15-denier fabric is the perfect thickness for an ultralight bag while remaining supple and doesn't have the "crinkle" sound of other bags. The vertical baffles do allow for some down shifting, but it’s easy to fix by worming the down into the less-filled areas. The Halo hood is an ingenious design, and I've never felt cold air coming in through the collar. The zipper is, of course, rather flimsy, but it comes with the weight savings. The zipper is not especially "catchy" if you take care to run the fabric out of the way of the zipper pull as you move it. There is a small Velcro pocket (4"x4") on the inside of the bag, which is good for small items like contact lens cases or lip balm. The Drift 15 packs down per the manufacturer's stated size, but you can get it about half of that length (about the size of a cantaloupe) by using a compression bag. One thing to note is that the tighter you compress the bag, the longer it takes for it to fully loft. If you've been on the trail all day, I'd personally suggest laying it out for the down to loft as soon as you get to camp. Sizing note – I’m 6’2” and the Regular Drift 15 is just long enough. For anyone taller, I’d recommend the Long. Overall, the Drift 15 is a standalone sleeping bag. I wouldn't be surprised if this sleeping bag line took over as the new industry standard for lightweight sleeping bags.

    Great bag!

    • Familiarity: I've put it through the wringer

    This bag is impressively warm for it's weight. I have tried other 2 pound bags with 20 ounces of fill and this one was just so efficient at keeping me warm. I think it has to do with the vertical baffles which prevent down from falling when sleeping on my side. The zipper on the bag gets caught all the time but that happens on every bag I've ever used.

    This bag is a serious 15 degree bag. This bag is absolutely not appropriate for June/July/August use in high elevation areas of the western united states unless you get abnormally cold. It's for near freezing/sub freezing temperatures.

    COZY, quiet, light!!!

    • Familiarity: I've put it through the wringer

    This sleeping bag is SERIOUSLY worth every penny! I've used this bag for over two years in all kinds of spring, summer and fall camping in the Rockies and PNW. It's kept me plenty cozy through rain, snow and sleet, and easily unzips to allow temperature regulation on hot summer nights. I'm no ultralight backpacker, but this bag packs down super tight, and weighs very little for the warmth it provides.
    The material is super cozy and soft, and is super quiet! It hardly makes any noise at all against my sleeping pad and my buddies' sleeping bags. I've also gotten it wet and/or muddy on multiple occasions, but it dries nice and fast in the sun, and can scrub clean on the trail.

    Holy crap. Holy crap. Like, there are no other words for how much I love this bag. I took this up to a trip in the PNW, and though it wasn't 15 degrees, it was a rainy, chilly weekend. I didn't bring a sleeping pad, due to my stubborn personality, and I was thrilled to feel like my bag was comfortable enough despite my lack of preparation. 10 out of 10 would recommend to a friend. Warm, padded, and light as a feather. Packs down nicely, too.

    Simply the best nights sleep.

    Everything about this bag was comfortable. The feel of the fabric, the temperature, and the way it fit in my backpack. I was nervous about using a mummy for the first time, but it wasn't a problem at all. I like to curl up, sometimes, and while it wasn't easy, I could still curl, when I needed to. I was especially happy because it was incredibly warm, and I'm a very cold-temperature person. I only gave it fours stars because I haven't taken it in 15 degree temps yet, so I don't know how well it will do. It got down to 40 degrees, and I was just plain hot. I had to get down to my skivvies, and then I felt warm and comfortable. (If you want ideas on what skivvies to bring, hit me up about that, as well!).

    It packed down very easily and was quite small. I was happy about that because I had to fit everything I needed in my pack, including a tent and stove. In the photo, it is the red bag. The other bags are my sleeping pad and the zero degree bag my partner was in. I wish I had something to nit-pick about this, but I just don't. I'm really in love with it and happy I found something that will keep me warm.

    More of a comment. In the specs, you list the EN lower limit at -7.1F. I believe this should be +7.1F.
