Overview
Big Agnes builds the Anthracite as a mummy-shaped backpacking bag with a contoured hood, a draft collar and an anti-snag zipper. Fireline Pro Eco synthetic insulation fills a recycled polyester ripstop shell that carries a water-repellent finish.
Synthetic fill and a water-repellent shell suit damp conditions, and the compact mummy cut favors low bulk over room to move. The limit is the missing warmth figure: the three-season label is the only guide to how cold a night this bag can handle.
Who it's for
Three-season backpackers of average height, particularly on trips with condensation or damp tents, are the target. Taller sleepers, restless sleepers who want space, and anyone who needs a documented cold rating should consider a longer or better-documented bag.
Pros and cons
- Synthetic insulation, recycled polyester shell
- Contoured hood and draft collar
- Lightweight, compact for backpacking
- Water-repellent finish without added PFAS
- Temperature rating not listed
- Mummy shape limits room to move
- Taller sleepers exceed the height limit
- Regular length only in this listing
Performance notes
Warmth comes from the synthetic fill trapping air, with the contoured hood and draft collar limiting heat loss at the head and neck. The mummy shape cuts dead air around the body, which helps retention but narrows the interior. Synthetic fill continues insulating when damp, and the shell finish sheds light moisture.
