What makes the Peregrine Altai unique is its ability to keep you both cool and warm. Comfort is a variable thing. Many people enjoy sleeping with their feet uncovered. With the Altai, you can do just that. You can completely unravel it and use it as a blanket if need be. It handles moisture remarkably well. The Primaloft down/synthetic blend is great for quick drying if it attracts moisture. If it attracts moisture, that is. It is also made with a durable 20D 380T Nylon Ripstop shell that sheds large quantities of condensation. Lastly, it wouldn’t be a Peregrine sleeping bag without a zippered pocket for quick access to essentials like a midnight snack, headlamp, or your phone.
