Does the UL Recovery Liner Actually Work?
The liner's Celliant fabric weaves bioceramic minerals into 100% recycled polyester that converts body heat into infrared energy to improve local circulation and promote faster muscle recovery. It's a real, purpose-built technology — not a gimmick — plus it delivers the practical benefits of any liner: hygiene and added warmth.
How Much Warmth Does It Add?
A liner like the UL Recovery typically adds roughly 5°F of warmth to your sleep system, depending on conditions. It also works as a standalone summer sleeping bag for warm nights, making it a versatile 3-season piece.
Can You Use It as a Summer Sleeping Bag?
Yes. On warm-weather trips, skip the full bag and sleep in the liner alone — at as little as 11 oz and packing to 8" x 4.5", it replaces a bag on summer overnights.
