Marmot 30°F Mystic Sleeping Bag - Synthetic, Mummy

Haven't had a chance to use this on the trail yet but I've had the heat off in the house since I've had it and sleeping on the floor in the house at 40 degrees and never woke once...she's a beaute Clark!

Super comfy, bought this for my girlfriend and she loves it

I was very warm when I used it. Though, haven't had the chance to push its limits in extreme temps. It is comfortable and very warm so far. The hood with drawcord is a plus. I got the zipper snagged a bit, but other than that I have had no issues.

I think the quality construction and thoughtful details really make a difference. this isn't a very compact bag when packed, but I always know it will keep me cozy-the draft tube insulates from drafts very well and the toe box doesn't get overly cold, though I'm also in the habit of throwing a jacket over the end of my bag on cold nights. I'd say the rating is accurate. the loft seems to hold up quite well to packing-it still feels new after a full summer of camping.

very warm. agree about the zipper, a little tricky to zip and unzip, especially for right handers because it is on the left side. otherwise, very excited to take this on a trip!

Good quality, I prefer down for fill but when canoe camping, water is everywhere and things get wet, synthetics stay warm(er). Close-out, price is right.

Bought this bag for my wife who is 5'8". If fits her well, but we will see if it's warm enough. It was so inexpensive, we can buy another if it's not.

[...] Totally fit our needs. Very pleased.

This product packs well for backpacking as it is small and light weight. I don't know how it would feel in very cold weather, as I only used in in weather that probably didn't drop below 40 or 50 degrees at night. It was comfortable and the hood was easy to sleep in and adjust. On the downside, I did notice that the zipper was easy to get hung up in the fabric...I am not a morning person, so that was a bit annoying to try and get open.

This bag was a great backpacking bag for warmer conditions. It is light and packed pretty small, could use a compression sack.
