Big Agnes Anthracite 20 Synthetic Sleeping Bag

Jump to: Our Verdict / Features / Specifications

A well-priced four-season bag that will get used out on the trail and, at home, on the couch too.

Big Agnes says: 

Our Anthracite 20° traditional mummy style sleeping bag is designed to be taken anywhere and provide rest after a long day outside. Stay cozy with Fireline™ Pro Eco recycled synthetic insulation and a roomier mummy shape than a traditional bag design. Lightweight enough to stuff in your pack for summer backpacking but comfortable enough for backyard campouts with the kids, this bag is so versatile and comfortable you’ll want to take it on every outing!

Our Verdict

Synthetic bags are go-anywhere bags; they survive well in damp conditions and keep you warm when they are wet. This is an incredibly reasonably priced bag for a sleep system capable of keeping you warm at -7, it’s not an “ultra-light” sleeping bag, but it’s a reasonable weight for a four-season sleep system. It’s not a bag I would take out in the depths of winter, but I would be happy to take it out on milder winter nights.

It’s a mummy shape and is of generous size; you have plenty of room to toss and turn, “no draft collars” and a baffle running the length of the zip means you won’t be displacing hot and cold air, so you stay nice and toasty.
