Initial Impressions

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

This seems like a very solid bag. So solid that it may as well be a down filled bivvy. I have yet to take it out into some real polar weather (I live on Baffin Island), but so far it feels like it will fit the bill.

It's got great loft, the double draft tubes are very plush, and the Long fits my 6'2" 170lb frame well, with room for extra layers, water bottle, etc.

It seems like MH used a bit more fabric than they needed to around the zipper. There are two double layered storm flaps that cover the zipper. The upper flap extends past the zipper all the way to the bottom of the bag for some reason. In spite of this, my Long version weighs in at 4 lbs, 9 ounces in the stuff sack - 11 oz. lighter than posted. I swapped in a different stuff sack, with 3 compression straps that run perpendicular to the direction of the sack and squished this bag down to almost half the size I could with the included stuff sack with only a 3 oz. penalty.

I got this on sale, at about half price, and am pleased with it so far. After I run it through its paces I'll update the review. 5 stars because I don't yet have a reason not to like it.

Frustrated

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

I just returned from an over night just north of Fairbanks Ak. The temperature was roughly around -20 degrees. The bag worked great but I have to admit that the zipper had me debating if I wanted to keep the bag. Are there tips and tricks out there that I am missing or is this just a design flaw. Every time I zipped the bag up or down the zipper would get caught, EVERY TIME! When it is negative twenty you do not want to be fighting a zipper.

Responded on

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.

Hope that helps.

Justin, thank you!!! I had a letter already written to MH over the zipper issue. I had just returned from my 3rd trip with the wraith and was disgusted with the zipper situation. I happened to search reviews and read yours. So far so good after taking your suggestion. I'm keeping my fingers crossed. Thanks again!! Tony

Out with the old and in with the new.

I was wondering why MH was sleazing these out this past season. The new bag is on its way and seems like a bunker compared to the last two Wraith models. I am still very happy with my purchase and especially happy about not paying close to a grand for the newest model. Though the new model makes me drool.

very warm

This bag is very warm, its rating of -20 is very accurate. I took this bag to Nepal, into the Himalaya, I never got cold and we had nights pretty close to -20 and I was fine in just my underwear. The down sides of this bag are the lack of a foot zipper so on the warmer nights it was too warm and the zipper gets caught sometimes, the entire zipper area is black so it can be hard to see what's caught in the dark. The bag is very water resistant and dries quickly if it does get wet inside. On a warmer evening, around 30, I woke in a puddle of sweat, I was able to soak up most of it with a towel, by the next evening I didn't feel any dampness in the bag.
