The best of an ultralight quilt and sleeping bag combined!

The Aerial 180 Sleeping Bag by Cumulus blends the breeze-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. The Aerial 180 is a comfy cocoon for warmer weather. 

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
• Hoodless design
• Independently filled top and bottom of the sleeping bag
  
• Side loops for mattress attachment to keep the bag in place even when you toss and turn
• Stitched-through chamber design construction
• Looking for warmer options with a hood? Check out the Aerial 330 and Aerial 250
