The Marmot Eco Pro 30 Sleeping Bag uses recycled materials to create a durable, water-resistant shell and effective insulation to keep you dry and warm in cold, wet weather. The shells and lining come from recycled plastic bottles. The EcoPro insulation consists of 80 post-consumer material transformed into a hollow-core continuous filament thats not only thermally efficient, but lightweight and highly compressible. Marmot designed this three-season bag with wave shingle construction, which uses overlapping shingles of insulation for maximum warmth even when wet. The 3D Nautilus hood wraps around your head and traps body heat, and the draft tube seals out cold air leaks. Stash a snack or alarm clock in the Eco Pro Bags pocket and burrow down into that recycled goodness.
