Nice Bag

[This review was collected as part of a promotion.] I'm really enjoying this bag. Packs small, and has good zipper placement for venting, sitting up, and even walking around. I tend to sleep on the cold side. I felt comfortable at about 45-50 degree temps. When it dropped below 40, I felt most comfortable with a 50 degree quilt thrown on top.

Go To Bag

[This review was collected as part of a promotion.] Great sleeping bag, perfect size to weight ratio. This is my new "go to" bag.

Ascent Down Sleeping Bag

[This review was collected as part of a promotion.] No review yet, backcountry trip in a few weeks The bag is definitely well made, expensive, but good things aren’t cheap and cheap things aren’t good

All I Ever Wanted!

[This review was collected as part of a promotion.] "Don't fence me in" as the song goes, and this awesome bag does NOT! Large zippered foot box allows my feet to be free! Zippered side vents for air, sweet air!! Snaps at shoulders that hold the bag (and excellent liner) up so you can make breakfast!!!! The hood is so cozy!! You will be able to customize your sleeping just like at home!! Leg out is too cold, but just the foot is perfect!!

Comfortable, Warm, Adjustable

[This review was collected as part of a promotion.] This is a great sleeping bag. Zipped up it is very warm, material is very comfortable and can be opened up when the conditions are warmer. Used in winter and summer
