Great bag for the money. I'm 6'2" / 170 lbs and don't have any feelings of constriction. I've only slept about 9 nights in this bag, none below freezing, and I have yet to sleep a night where I don't wake up and unzip the bag all the way because i'm so hott in it. In my opinion, the bag is very light, but then again i'm a young energetic kid so others may feel differently. Seems like great quality, and i'm lovin it for the price.

Great bag. Kept me warm in cold colorado weather and I wasn't sleeping in a tent. Dried quickly after the late night frost. Great deal.

I bought this bag before a two week trip to Idaho. Although it never got terribly cold the bag kept me nice and toasty the whole time. On the warmer nights that we had, the dual zippers offered up nice ventilation to keep me cool. The bag is quite lofty and with just a thin foam thermarest I slept comfortably for the entire two weeks. Further, the little stash pocket is handy for putting any extra things you can't fit into the pouches of your tent. Overall, I'm very pleased with this purchase.

I'm 99% sure that you can't get a better bag for the price. I just got done testing the bag in my backyard here in duluth mn on an 8 degree night. I wore an acrylic stocking cap, 1 wool sweater with a thin polyester longsleeve shirt underneath, jersey pants with midweight fleece pants, and just my polyester hiking sock liners. (slept on a prolite thermarest). The only reason why I didn't sleep well is because I was stressing that I would wake up in the middle of the night without feeling in my toes but I slept comfortably warm.

All 4 summer trips i slept with the bag totally zipped open.

It's a well constructed bag with good quality materials and workmanship. For a synthetic bag, it packs well enough to backpack with. I haven't given it a good test in cold weather yet, but it looks like it will keep you warm to below freezing. I like the 1/4 length offside zipper - good idea to help cope with warm weather use. I'm 5'11" - average height and average build (165 lb) and the regular bag just fits - go for a bigger bag if you're any taller or wider. My only criticism is I'd rather it had a full length zipper that went all the way around the feet, instead of the 3/4 length with box foot.

All up, I think you'd be hard to find a better synthetic bag at a lower price.

This is a great bag especially for the dough. It's rated at 15º but can go well below that. It actually compresses well, a lot better than expected. Zippers don't have up at all so far. Doesn't snag easily and stayed dry even in a pretty damp tent. I'd recommend this to anyone wanting a really nice bag that is worth far more than they're charging!

Got this as a gift for a friend's wedding. We hooked them up with the ladies and the men's and they love 'em. If you think about it, get the left zip and the right and zip 'em together. That way, inter-tent coitus doesn't have to freeze your arse. Seriously, great bag for the price.

I'm a pretty big fella (6'5" 290 lbs). I purchased the Mtn. Hardwear Switch bag a couple years year ago because it has a feature that allows the bag to be expanded by 8 inches. Even with this fully unzipped, so as to get the greatest girth out of the bag, I felt much more constricted than I would like from a 3 season bag.
This Marmot bag is just awesome! I fit in comfortably, and there is still room to sit up (with the hood on!) and move around a bit when sleeping. From a big guy, this bag is just awesome. Get the extra wide, it's worth it.

Not the lightest synthetic bag you can get but for the money it's not too bad. I used this on a 4 day / 3 night trip in the Selway Bitteroot wilderness and am overall very pleased with this purchase. Dual zippers offer good ventalation and warmth was more then enough for the cool rainy nights.

I bought this with the intent of not having to need a pad and it worked great. First night I slept inside of the bag and the second I slept on top of it. Worked great. The dual zippers give you enough breathing room when its warm outside. Didn't get any condensation from sweat. The bag packs pretty well but is a bit of a pain to get it back into the included sack in a tent.

This is a great sleeping bag. It is super warn. It's nice to have the option to zip half way down the left side. The stash pocket is also great for keeping a headlamp in for the night. This is a great bag for those chilly nights on the trail.

I love this bag. When my old bag failed me while abroad, I went for it and purchased this Marmot bag. It dries quickly, is ridiculously warm far below 15 (think sweating), compresses pretty well, and has served me well on many trips! Great price too.

The bag was warm but I want a lighter and more compact bag for lightweight backpacking.

It's a well made bag: good design, good materials, good workmanship. I'm 5'11" and 165 lbs and the regular bag just fits - if you're any bigger, get the larger bag. For a synthetic bag, it packs small enough - if you need smaller, then buy down. The zip is 3/4 length, I would have preferred full length. I haven't field tested it in cold conditions, but it does look like it will keep you warm at below freezing temps. All up, you'd be hard pressed to find a better synthetic bag at a cheaper price. Ordering and delivery was fast, professional and painless.
