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.
