    • Familiarity: I've used it once or twice and have initial impressions

    I borrowed this bag for a "Spring" skiing trip to Wyoming. Being Wyoming, this involved one night of well below-zero temperatures and I was overjoyed that I had this enormously lofty sleeping bag to seal myself inside of. This is a true -20 bag and I was completely comfortable sleeping in just light base layers even in subzero temperatures.The waterproof membrane was also awesome - while others struggled with damp sleeping bags as frost melted in their tents during the day, the moisture just beaded up and rolled off of this bag.

    The cut is generous. Plenty of room to toss and turn at night and not claustrophobic if you have to bunker down for a day during a storm. It's also great if you have ski boot liners or water bottles you need to stuff in your sleeping bag overnight so they don't freeze. The one downside is that all the volume inside means it does take a little while to warm up if it's super cold out.

    Size-wise it's big and bulky, but pretty reasonable for a -20 bag. And if you're going on a trip where you actually need a bag this warm, the size and weight are probably a non-consideration.

    Almost Too Warm

    • Familiarity: I've used it once or twice and have initial impressions

    I've used a number of different sleeping bags over the years and this one definitely impressed me. Although weather kept us from using the bag in the conditions I brought it for on a trip, I will say that this bag is awesome overall. It packs up surprisingly small for a -20 degree bag and it doesn't weigh a ton either. Further, at 6' 0" it fit me perfectly in the regular size and kept me incredible warm, although again, I never got to put it to the full test.

    Definitely a bag I would trust in sub zero temperatures though

    Ultimate winter bag

    • Familiarity: I've used it once or twice and have initial impressions

    This bag is super bomber! First impressions.. the zipper is serious! I can't imagine this thing ever blowing out. Also, the outer shell of the bag feels incredibly abrasion resistant, and is also water proof and breathable. And not to be overly redundant, they even have a Q shield down that prevents the down from wetting out and losing insulative properties if you happen to puncture a hole and get water inside. While I say that a waterproof shell and water resistant down may be redundant, it makes perfect sense to protect you from that situation. Because if you're in an arctic environment in which you happened to destroy your insulation by wetting it out, it could quickly turn to an uncomfortable or even potentially dangerous trip. I was able to test it out in Big Cottonwood Canyon in October. The temperature got into the twenties and was a bit wet with rain and sleet (not that it was inside of my tent). But I was plenty warm in shorts and a t-shirt and could tell that this would suffice in much colder temps.

    Tested 5 chose 1

    • Familiarity: I returned this product before using it

    Okay, so my review is based solely on "fit" for a tall guy. I bought five winter sleeping bags to test- feel, comfort and dimensions and how durable the materials "felt". In the end I kept only 1 (Marmot CWM). As I sent the 4 others back and did not try them in actual sleeping situations, I cannot comment as to their performance in cold weather- only fit and initial comfort for a 6'6" guy who weighs 215 lbs.

    about the Wraith Sleeping bag
    - Looked durable and exterior felt like it would probably do really well again wet weather.
    - Very warm- could likely handle cold weather without issue- down fluffed up nicely.
    - Length was okay for a 6'6" inch guy, though not much room to spare.

    - I found this to be the case with all the mountain hardwear bags- the shoulder circumference was too tight for me. I'm somewhat muscular and have fairly broad shoulders and while I could fit, it was a little snug, not to the point that I felt claustrophobic, but all the mountain hardwear bags were tighter than the Marmot bags. For a slightly more slender person, I'm guessing it still would be quite comfortable.
    - The footbox was a little small for my liking. I don't have massive feet (I guess that's relative, I wear a 12.5 shoe), but the foot box was more constrictive and was just not as comfortable as the Marmot equivalents.

    In the end, out of the 5 bags I bought, I probably would have still picked this second of the five, but primarily for it's water repellant properties. Otherwise, it would have been in my bottom 3.

    Summation: It's obviously a good, quality winter bag. If however you're broad shouldered and like a little more space, Marmot might be more comfortable in that regard. Also, note that I did not have any of the zipper issues as mentioned in the other review. In fact, I had more zipper snag issues with the Marmot bags than I did with the Mountain Hardwear bags.

    Great maybe...

    • Familiarity: I've used it several times

    I have used this bag 3 times and have been so frustrated with the zipper that I was either going to just sell it or contact MH for a possible solution. I happened to find a review where another owner said to make sure these very small flaps are in the correct place. Here is his explanation and thanks again Justin!!

    "When I was putting this bag through a trial run I noticed the zipper getting stuck too. Every time. After really looking at what was going on, I figured it out.

    On the back side of the zipper, there are two very narrow pieces of fabric that are supposed to keep the zipper from snagging on the draft tubes. On other designs these strips are sewn directly onto the draft tubes.

    The issue is that when my bag arrived, the zipper was already running over these strips and causing the zipper to stick. carefully running the zipper forward while pulling the strips away from the zipper freed it up.

    Now the zipper slides freely, and these two strips do exactly what they're supposed to do, cover up the zipper and keep the draft tube out of the way.

    I've done a lot of test zipping to see if the zipper will eat those strips again, but it hasn't yet. "

    I have tried it at home and its seems to work fine will be testing it again this weekend.
