## Description

desertcart.com : Sea to Summit Reactor Sleeping Bag Liner, Fleece Compact (78 x 31.5) : Sports & Outdoors

Review: Warm and comfortable. - Kept me pretty warm with my 32F down sleeping bag in 25F weather. My feet got a little cold but wasn’t bad enough to keep me up all night.
Review: Great liner for summer months - i’m not keeping this because I need something a little warmer. I’m getting ready to start the Appalachian Trail and I just don’t think this is warm enough for me looking for a warmer insulated liner for my sleeping bag. If I wouldn’t be hiking in the cold, I probably would’ve kept it.
