Mammut

Perform Down Sleeping Bag: 19F Down

One week in the Grand Canyon from 30-50 at night and slept great. Rained last 3 days but bag outperformed and a little damp kept me warm. Great value at discounted price. Center zipper a bit getting used to but worked well. No sleeping on your side with a zipper underneath you.

Zero Complaints

This bag is extremely comfortable, it condenses down to a very small size, and clearly uses high quality material. Has been nothing short of amazing on cold nights in the mountains. Love the middle zip, too.

Amazing!

So warm and compacts to a small size for backcountry adventures!

Warm & Comfy

The most comfortable bag I have tried in this temperature range. The zipper is fabulous and doesn't snag, the inside is soft and I felt really warm sleeping with nothing but underwear at -1 Celsius. It packs small and the earplugs and mask are a small bonus

Best sleeping system I have ever used.

I did a week of camping around the southern Okanagan on a rock climbing trip and slept in the bag each night. Slept like a king every night. The eye mask blacks it out and there are a set of ear deci damps. The sleeping bag is super comfortable, highly functional zippers that don't catch on the fabric. I could go on and on but this sleeping bag did not disappoint on any level.

Lightweight and Comfortable

This sleeping bag packs very small, perfect for backpacking. It's very comfortable and keeps me very warm

Great bag!

Good fit for me, 5'11" and 172 lbs. I like the ear plugs and eye shade that come with it. Warm enough for early spring camping.

Good quality bag. I tend to sleep with my arm under my head, so the tightness of the hood isn't ideal. Otherwise it's plenty warm, the zipper is snagless, and it packs pretty tight.

Lightweight, Compactable, Super Warm

I haven't had a chance to take it on any excursions but have used it for car/ tent camping and have woken up sweating on multiple occasions. The down packs very well and doesn't stay bunched when unpacked. Zipper doesn't snag and the complimentary sleep mask is a nice touch for people who struggle with light sensitivity.

Very confortable and soft. It is also quiet, I move a lot so it's good for my girlfriend too. The best part is the central zip with the anti-snag, you can't go back to side zip after trying it. Overall it seem tough, I sleep 1 month in it. Con: it's not the most compressible sleepingbag
