Aerial 330 Sleeping Bag by Cumulus

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)? Check out the Aerial 250 or Aerial 180

• Aerial 330 Sleeping Bag
