Experience the great outdoors in comfort with the ALPS Mountaineering Crater Lake Outfitter. This synthetic sleeping bag is perfect for three-season camping, designed to keep you cozy in temperatures as low as 20 F / -6 C. Its durable 210T nylon ripstop outer fabric and TechLoft Silver insulation are complemented by a unique feature: a removable poly cotton liner. This liner can be washed separately, extending the life of the sleeping bag. The bag also includes a right-sided #10 zipper and comes with a stuff sack for easy transport. Sustainability is not forgotten with the use of recycled or repurposed materials, offering both comfort and eco-consciousness for your camping adventures.
