      fits well

      This bag fits me well with some wiggle room. I doubt I will be summer backpacking with nights below freezing, but I sleep cold so this will be a luxury. I have Teton Sports backpacks for trips (Explorer 75 and 85, for use with different size tents) and this sleeping bag compresses enough to fit in the bag department in both packs. All features are functional. I keep this laid out flat under my bed, making it always ready for a quick pack into pack and will quickly be ready for use after a day hiking.

      Warm and Light!!!

      A super lightweight bag that is comfortable and warm! I used it in 20 degree weather with 2 inches of snow on my tent and I was surprised at the warmth. Would recommend, though I would wait for a sale since I bought it for $80!

      Best Bag

      I had been needing a new sleeping bag for a while and decided to try out the Altos S. It exceeded my expectations, it is super warm and comfortable. I would definitely recommend it for any age or gender.

      Solid Bag

      I've been using this 4 seasons for the last couple of years. It pairs well with either my milsurp bivvy or hammock. My only complaint is that it isn't available in more natural colors. Keep up the good work, guys.

      I was skeptical at first because of the light weight of this bag but I used this bag in 24F degree weather at night in the mountains of PA and I have to say I was pleased with its performance. I was very warm and it was super comfortable. I didn't have to use a second bag or blanket which was nice. It's cold at first because it's not a flannel lining but if you get a micro fleece lining for this bag, it turns into an oven. I don't plant to get out in much colder weather so I think I found a keeper.
