Why We Like The Perform Down Sleeping Bag

The Perform Down Sleeping Bag is an easy choice because it acts as our nighttime coverup in the backcountry, whether it's December or July. That's because, aside from the super soft and lofty down fibers keeping us warm, Mammut designed their own specialized mummy shape to keep in the heat. They also moved the zipper from the side to the top to better regulate temps when snuggling up in the bivvy or tent.

So comfortable and so packable. I spent more nights under a tarp than in a bed the past 6 months and this sleeping bag has been incredible. Hood is slightly smaller than ideal but middle zipper makes it so much easier to find at night. Added sleep mask and ear plugs have been such a great bonus these bright summer mornings!

Excellent bag

This bag is very warm, comfortable, and packs down well. I took it on a 5 day backcountry trip at Mt. Rainier at elevation and stayed toasty on cool, damp nights. The center zipper is a great feature, especially for a sleeper who shifts positions all night. I did not give it 5 stars because I broke out in hives the first time I used it. This was remedied by letting the bag air out in the sun, inside & out for a day. Overall, I love this bag!

This sleeping bag is like being wrapped in your favorite hoodie, so cozy! The material seems durable and doesn't make noise every time you move. I would definitely recommend it if you are cold blooded like me. I have yet to try it in below zero temps, but I am very happy with it.

Comfortable and warm

Very confortable and warm, that sleeping bag has a very premium feel overall. Easy to use draw cord allow to cinch the hood and collar independently to dial airflow. The antisnug zipper is also very efficient.

Warm and comfortable sleeping bag

I usually run cold but was warm all night on a hut trip last weekend. In fact, I had to open it up to cool down at one point. Packs down small and the inclusion of ear plugs and an eye mask is a nice touch. The zipper is on the front too as opposed to the side which I found more comfortable.

A bit big for someone is small but the room is appreciated as someone who is an active sleeper! Would buy from the brand again. Slept outside over Christmas and it was blissful and very warm, we did have mild temps. Excited that this will still be comfortable in colder weather.

packed small!

This bag packed small, was so warm ( too warm for 0 degree weather so I loved it) and the storage bag plus carrying bag it comes with are so nice! It's not the smallest packing bag but it packed surprisingly small for a -10c bag and was very light. I am 5'3 and 130 lbs and it was big for me ( what isn't though lol) but I like my sleeping bags a bit bigger so I can really cozy in. . It snowed on us in a summer tent so we were damp and this kept me warm no matter what.
