Cozy And Warm

[This review was collected as part of a promotion.] This is by far the best sleeping bag I’ve owned. I used it in 40 degree weather and was warm, even though I tend to be cold normally. I love how small it packs down and it’s ultra light. Great investment for sure.

This Bag Is So Cozy

[This review was collected as part of a promotion.] This bag is so cozy and the color is beautiful. The zippers on both sides are such a great thing for me as I typically sleep facing the opposite side the zippers are on other bags and my dog crawls in to sleep inside with me. There’s plenty of room for her to do that with this bag also. We took it on our first adventure backpacking to a fire tower overnight and it was plenty warm in the 20s with my liner, wearing just a base layer. I can’t wait to take it on more adventures when the weather warms up and see how it holds up but I’m already very happy with the purchase!

Pretty Good

[This review was collected as part of a promotion.] The sleeping bag is made well, very comfy feels cozy, and not noisy. The width was great and not too snug sleeping in undergarments but would have been crowded with heavy sleepwear. I wish I would’ve ordered a longer and colder bag. Sleeping Id roll further into the bag and the foot box was cramped lengthwise (im 5’6”). I did not attempt to use the bag solo nor would I because it was so cold, icy, & damp. I used a liner (game changer!) and a secondary sleeping bag unzipped on top as a blanket.

Altitude Women's Down Sleeping Bag 15°f

Wow, I went from a summer flannel sleeping bag that I would freeze in to a cascade of down comfort comparable to nothing you could possibly imagine. I'm is awe as a first time user. It takes a while to wrap your head around the price, but once you jump in, there is no turning back. I highly recommend! I also purchased a liner that can be used alone or with the down bag.
