Women's-Specific Sleeping Bag for Reliable Warmth Anywhere
The Big Agnes Anthracite 20 sleeping bag is designed specifically for women, combining a traditional mummy-style shape with enhanced insulation for cold-weather camping. Whether you're heading into the backcountry or setting up in the backyard, this 20 degree sleeping bag offers dependable comfort, warmth, and easy packability in a regular size sleeping bag that's ready for any trip.

Eco-Friendly Warmth with FireLine Pro Insulation
Insulated with FireLine Pro synthetic fill, this recycled sleeping bag uses multi-denier fibers to trap heat effectively while staying lightweight and compressible. The insulation is soft to the touch and holds its loft in damp conditions, making it a top-performing choice for campers who value both comfort and sustainability. This FireLine Pro sleeping bag is a reliable option across a wide range of camping environments.

Recycled Materials and Weather Protection Built In
This eco friendly sleeping bag is made with a recycled polyester ripstop shell and taffeta lining, both treated with a PFC-free water-repellent finish to shed light moisture. Offset quilting helps distribute insulation evenly to prevent cold spots. The lightweight construction makes it a great choice for hikers who need a synthetic sleeping bag that performs well without extra bulk.

Designed for Comfort, Warmth, and Function
A contoured hood, no-draft collar, and insulated zipper tube help keep warmth sealed inside. The low-profile cordlock allows quick hood adjustments with one hand. A smooth anti-snag YKK zipper makes getting in and out easy, while the two-way function adds ventilation and flexibility. The regular sleeping bag uses a 55" zipper, and it can also zip together with a compatible all-gender Big Agnes bag for shared warmth.
