CELLIANT is a fabric technology that converts body heat into infrared energy, clinically demonstrated to support faster recovery from fatigue and improved local circulation and sleep quality. Integrated directly into the liner's fabric, it works every night you sleep — no batteries, no effort, just restorative rest so you're ready for the next day on the trail.
Yes — as an enclosed liner inside your sleeping bag or quilt, it adds a measurable layer of insulation, effectively boosting your sleep system's warmth. It also works standalone in warm weather as a breathable sleep shell.
Machine wash cold on a gentle cycle with mild detergent, and tumble dry low or hang dry. Washing regularly protects the CELLIANT fabric performance and keeps odors and oils out of your sleeping bag.
Compared with standard cotton liners, the UL Recovery is far lighter, packs smaller, and adds clinically demonstrated CELLIANT recovery benefits. Compared with sleeping bag-only systems, pairing this liner extends time between washes and can add warmth — one purchase, three benefits. It pairs naturally with Big Agnes quilts and insulated sleeping pad covers.

Skeptical of CELLIANT marketing, but after back-to-back hiking days I genuinely woke up less stiff than usual. Regardless of the tech, the liner is silky, packs tiny, and keeps my bag clean. Win-win.
Barely notice it in my pack. Adds a few degrees of warmth on chilly nights. The fabric is soft against skin.
Light, soft, keeps bag clean.
I'm a restless side sleeper and the cut feels a bit confining — I ended up tangling with it nightly. For still sleepers it's probably perfect. Material quality is excellent.
I'm 62 and recovery matters more to me than it used to. Day three of a backpacking trip used to wreck me; with this liner I woke up noticeably fresher. It also means I can stretch the time between washings of my down bag, which is good for its lifespan. Packs down smaller than a Nalgene.
That's the main job and it does it well. The recovery fabric is a bonus I can't fully verify, but I do feel less groggy. Slightly slippery feel takes one night to get used to.
The flatlock seam at the shoulder caught my ear and neck all night. Sensitive-skin folks, beware. Otherwise well made.
Doubles as a hotel bedding barrier on business trips. Ultralight, packs to nothing, and the fabric feels great. Big Agnes quality as usual.
