This bag is a high quality mummy bag. it is not, however, an alternative to those that feel too constricted by the mummy. I bought this bag hoping that its elasticity would be an alternative to the traditional mummy bag. When I got it, I realized that though it stretches, it's still really constricting. If you want something you can move in (or that moves with you), this isn't the bag. I returned it for the Big Agnes.

On the plus side, the MontBell was incredibly warm and true to size. I am 5'11" and just fit in the regular size bag. If you are taller than me, you should get the bigger size. Construction was good. Zippers worked well. Compressed decently.

This is an awesome bag! I got one for my girlfriend for her birthday, and was a little nervous, because she is a very cold sleeper, and because I wasn't super familiar with MontBell's products. This bag blew me away and exceeded every expectation I had. Oh, and it kept her warm too. The elastic around the bag makes it very efficient, while still being comfortable. We were in fairly cold weather (about 20-25 degrees overnight) and she was warm as could be, which is pretty rare. 5 stars and two thumbs up!

I can't stop the grin on my mug. This is the coolest sleeping bag ever! The baffle at the bottom is a cool little feature to throw your water or shoes in so they stay thawed out in the super cold nights. This bag sleeps really warm, especially for women. Women sleep colder, and I would still say that this sleeps you to 0 Degree warmth when needed. When in the bag you can move so much, I would even say it feels like you could probably fit a mate in with you *If you wanted to be close like that ;)! Also I live in Utah, and with the wacky weather I think this is a great degree choice for whenever use. When it is warm I have just unzipped my bag and used it blanket style.
