Aerial 330 Sleeping Bag by Cumulus

Ships in 1-2 business days | Based in Poland | Est. 1989 The best of an ultralight quilt and sleeping bag combined! The Aerial 330 Sleeping Bag by Cumulus blends the warmth-trapping design of a sleeping bag with the ultralight efficiency of a quilt. Traditional sleeping bags compress under the sleeper's body weight, relying on the sleeping pad for insulation. The Aerial solves this with a single layer of ultralight fabric on the bottom, eliminating the need for additional down, keeping the price and weight lower. Unlike a quilt, Aerial's sleeping bag style construction traps in heat and protects from cool drafts and annoying bugs. You will be sleeping cozy and warm in the Aerial 330.  Features: Single air-sealing layer of fabric in the bottom of the sleeping bag No zipper Minimalist, weight-saving design and components Close fit mummy shape Differential cut design 3D-shaped hood design with two different hood draw cords for comfortable adjustment in the dark  Independently filled top and bottom of the sleeping bag Advanced foot area construction for better protection  Side loops for mattress attachment to keep the bag in place even when you toss and turn Trapezoidal chamber design construction Looking for warmer weather options (with less insulation)?
