Meet the Katahdin 0 F Sleeping Bag

Synthetic, 100% Vegan, No Compromises The premium Katahdin hydrophobic mummy sleeping bag uses advanced synthetic fibers instead of traditional down, yet sets a new benchmark in lightweight, compressible down-like fill materials. Our ClusterLoft synthetic is more durable than down and performs better in wet conditions for warm, 4-season comfort. Professionally designed for thru-hiking, backpacking, and bike-packing.

Hydrophobic, Down-like Performance from a Synthetic ClusterLoft is our 100% Vegan synthetic fill. It's clusters of microfine fibers developed to simulate the compressibility and heat retention of down, resulting in a 625 fill power equivalence. More affordable than down, with increased resistance to matting. Our best bags for retaining heat in wet conditions.

Ultra-Lightweight & Ultra Compact Our ClusterLoft Advanced Synthetic insulation boasts a higher warmth-to-weight ratio than most other synthetic sleeping bags. And, because it's synthetic, it's both more compressible and durable than down, giving you a high-end sleeping bag that is incredibly versatile.

USA Based Company Gear That Gives Hyke & Byke LLC is committed to eliminating poverty through Kiva sponsors and is a member of the Conservation Alliance. Designed for Adventure and Designed in the USA, our mission is to create honest, top-quality, and innovative gear for you to live your adventures.
