My husband and I just finished a 230 mile hike in the high Sierras and we both carried this bag. It was fantastic. Not only did they keep us warm but we could move around freely like I've never done in a "mummy" bag. We absolutely love these bags.

This is my second Montbell Super Stretch Hugger down sleeping bag. I love these things. They compress down to the size of a Nalgene bottle, weigh next to nothing, and are of the highest quality. In addition to this, the "Super Stretch" feature of these bags is awesome. I get claustrophobic in standard mummy bags and definitely don't have that problem in the Montbell bags. I can stretch, spread my feet apart, move around and the bag lets me do it all. Long story short...they are a few bucks more than other brands out there, but WORTH EVERY PENNY.

I bought this sleeping bag because of it's light weight and all of the good things I've heard about it. When it arrived the first thing I did was to pack it into the included stuff sack and weigh it. Sure enough it weighed 1 pound 12 ounces, just as advertised, on my small, mechanical, postage scale. While I didn't use a ruler to measure the stuffed size I'm guessing that it's about 6 inches by 14 inches. The material it's made of is soft and comfortable making using this bag a pleasure. So far I've used it 3 times and been plenty warm. The night time temperatures were in the mid 30s the first time and the mid 20s the last 2 times. I wore a tee shirt and very light weight long underwear in each case and was plenty warm even though one of the colder nights was in an open shelter along the Appalachian Trail. The regular length bag is for people to 5"10" tall and you can believe that. That's how tall I am and I can't imagine anyone taller using a regular length. The stretch feature is great and makes for a good night's sleep for someone who moves as much as I do in their sleep. Next I'll try it in even colder temperatures.

So, if you're looking for a light weight bag, that compresses small, and keeps you warm down to it's rating, this may be the bag for you.

I'm a sprawler and this has been the perfect bag for me. Temp rating has felt accurate, although I haven't taken it all the way down to its rated temp yet. Because of the stretch feature I'm sure I could easily wear a lot of extra layers without compressing insulation. Mine weighed exactly what Montbell claimed which is a bit surprising. The shell material feels very fragile but has held up well thus far. My only complaints are that the zipper sometimes gets caught on the shell if you aren't careful, not a big deal and a common problem with bags. I wouldn't hesitate to buy this exact same bag if my existing one was lost or damaged, and I doubt I will ever buy any bag that doesn't have the super stretch feature.

I picked this up with a 30% off coupon, and sadly that is probably the only way I would buy this bag again. I am 5"10' and ordered the "Long" since I didn't want to be cramped. This bag is fantastic, it doesn't hug the body as much as I thought, but the stretchiness is nice for sitting cross-legged during breakfast, plus with the cinch at the bottom I can make the bag a bit shorter. Perfect for those who can't do the mummy bag thing and need to sleep with their knees raised. I don't know if 25 degrees is really accurate. I slept in about 35 degrees and did wake up a little cold, I was wearing a long sleeved top and boxers, so maybe pick up some thermals. I did add a polyester liner and that kept me much warmer, defiantly rated to 25 degrees with a liner.

Despite what I heard the Long doesn't pack up to the size of a Nalgene bottle, more like the size of a Dura-Flame log. All in all, I really like this bag, but I wouldn't pay full price.

This is a seriously comfortable bag. The stretch is effective, I think, allowing you to move while minimizing airspace when you're still. The material also contributes to the comfort factor, making it a joy to sleep in. I think the temp rating is probably right on. I just spent 5 nights in the Tetons and one night it got down just below freezing, and I was comfortable in this bag inside a 3-season tent with just a lightweight wool layer on and without even fully mummying-up. I do tend to sleep warm, but I think with extra layers I could push below the 25 degree rating in this bag. It's wonderfully compressible, too, taking up so little room in my pack. So far, I'm very happy with the purchase.

This is my first stretch sleeping bag and I am very pleased with it. The baffle system keeps the down where you need it and the stretch keeps it close to your body without feeling confining. The material is like silk to the touch. I have only used it twice so far where it was in the very low 30s and slept warm in a light base layer. It certainly must meet its' cold rating. Packs up super small and light.

I'm not a large person, but very broad and I have always found sleeping in any backpacking bag to be uncomfortable to say the least. There is nothing worse than a bad night of sleeping, tossing and turning, in a tight bag. I found this sleeping bag to be unbelievably comfortable and the temperature true to its 25 degree rating. With extra layers (the bag stretches) I am good down to 15, although I am a very warm sleeper. Completely zipped up, I can sit up and take off my socks. How many broad shouldered people can say that of their sleeping bag. At the same time it feels nice and close when you are stretched out to sleep. The bag is light, compresses nicely and really delivers on all fronts. I am extremely happy with my purchase. This is the first time I have been able to say that for any sleeping bag.

i've only slept in the hugger line of bags. I feel like its the best fit for me because i move constantly at night. I enjoy the bag however i'm not sure if its all that warm. I havent tested it in real cold temperatures but in the summer in the moutains in the east coast i find myself bundeling up very tightly. That may be because i'm in a hammock though. 4 stars only because its super expensive, cant the chinese make something cheaper?

I purchased this bag for my wife for our trip to New Zealand. She is a very cold sleeper, it got into the low 30's at night, for once i heard no complaining from her. This bag is super warm, super roomy, and super light! I have not seen a bag with a better warmth to weight ratio!

I used this bag for 5 months EVERY night while hiking the AT, and I put it to the test!! I am only 5'5" but had two 55lb dogs with me who have to sleep touching me. Yes, we all fit in this bag, the stretchy material has a lot of give! Don't get me wrong, it was tight and on the nights in the teens I was a bit chilled just because I was pushed up against it very tightly. This bag withstood dirty, wet dogs with scratchy, worn pads for 5 months, with only little wear. I will never buy a different bag, unless this one actually does wear out some day, then I'll buy the exact same bag.

..because this bag will hug you all night. It doesn't get much better than this; a quality product to say the least.

"cant the chinese make something cheaper?"

Think about your statement before you make it. Maybe you should be shopping at Walmart.

Finally I've found a bag I can get a good night's sleep in! Other mummies are too constricted for me - a side sleeper that raises one knee to waist-high. This bag is so comfy cozy cuz it nestles around you, but stretches where you need it to. So nice and lightweight too. The only thing is I would rate it at about freezing BUT I am a VERY cold sleeper.

The title pretty mush says it all, I bought this bag because it was light and packed small, but mostly because of its advertised "super stretch". I hate being confined in a tight bag so I went for it with this one. I have to say it wasn't really all I had hoped for. Really it doesn't seem all that stretchy. But when you get into it and start squirming around you start to notice that it really does do a pretty good job stretching, it really doesn't seem all that confining. I think I just got my hopes up a little too much, it isn't quite as stretchy as I had expected, but overall much more forgiving then a normal bag. Warmth wise this thing is hot. Granted my only use of it was 14 nights throughout the Patagonian summer and it never got down to the 25 deg the bag is rated, so I generally slept with the bag unzipped.
