The Story

The best of an ultralight quilt and sleeping bag combined!
The Aerial 250 Sleeping Bag by Cumulus is a mid-season bag that 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.
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 sleeping bag
- Side loops for mattress attachment to keep the bag in place even when you toss and turn
- H-shaped chamber design construction
- Check out the warmer (Aerial 330) and cooler (Aerial 180) versions of this bag style
Includes:
- Aerial 250 Sleeping Bag
- Simple mattress attachment system
- Stuff Sack
- Storage Sack
