      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.
