Sierra Designs 40°F Mobile Mummy 1.5-Season Sleeping Bag
Closeouts. Sierra Designs' 40°F Mobile Mummy 1.5-season sleeping bag is part jacket, part sleeping bag, and all warmth. Its revolutionary design features a dual-slider center zip that makes it easy to get into, and it also has arm ports and footbox toggles for comfortable movement around the campsite while wearing it.
Reviewed by Chousefield from Colorado on Tuesday, September 12, 2017Great bag. For the insulation it's nice and lightweight. It was in the low 40s at night and I was very comfortable. I really like the arm holes to get your arms out and cooled off.
