About Big Agnes Ultralight Recovery Sleeping Bag Liner, Long
FEATURED REVIEWS
Believe it or not, it works.
Whether you believe it or not, I feel that it really does work. If you don't believe its recovering abilities, it's still the comfiest bag liner I've ever used. At the end of the day, having a washable layer between you and your bag is a game changer, especially when on the road/trail for days or weeks on end. The fact that it can make you wake up feeling recharged is the cherry on top.
A perfect little thing
The liner has become a valued part of my kit since I received it for testing last year. Both on extra cold nights when I need 5° more insulation as well as camping on 80F+ nights when I want some coverage but my main 0° bag is far too warm to tolerate. Y'all know how you need at least one leg under the covers no matter how hot it is? This is perfect for that. I can't speak to the recovery aspects of the ceramic coating as my pre-release liner was simply for durability testing.
Enhanced Recovery for the Trail Ahead
Designed for high-performance backcountry adventures, the Big Agnes Ultralight Recovery Sleeping Bag Liner helps you sleep longer, recover faster, and wake up ready to move. This ultralight sleeping bag features integrated CELLIANT bioceramic recovery technology, clinically shown to promote improved sleep and accelerate post-exertion muscle recovery. Whether you're pushing miles on a thru-hike or camping off-grid, this Big Agnes Recovery liner boosts your sleep system's performance without adding bulk.
Recovery-Focused, Thermoregulating Performance
The moisture-wicking sleep liner is made from soft, recycled polyester infused with CELLIANT fibers, which convert body heat into infrared energy and reflect it back to your body. This process has been proven to enhance local circulation, improve cellular oxygenation, and support better sleep quality. The liner also helps maintain optimal temperature-whether you run warm or cold, making it an ideal thermoregulating sleeping bag for any season or sleep preference.
Packable Protection and Versatility
Beyond performance, this compact anti-odor sleeping bag protects your sleeping bag from dirt, sweat, and body oils, extending its lifespan and reducing wash frequency. A minimalist cinch-hood closure allows easy temperature control, and the liner is reversible to fit both right- or left-zip bags. With a soft hand feel, durable seams, and packable design, it's a versatile option that can also stand alone for warm-weather overnights or lightweight travel.
