Celliant to boost hiker’s sleep and recovery

Big Agnes, a maker of outdoor equipment based in Steamboat Springs, Colorado, is introducing an innovative sleeping bag liner made from Celliant with Repreve. Developed by Los Angeles based Hologenix, Celliant is an infrared-reflecting fibre that is said to promote thermoregulation, enhance local circulation and improve cellular oxygenation. These are believed to create the conditions for better sleep and recovery. Repreve is a branded recycled polyester produced by Unifi. 

The UL Recovery Liner with Celliant is priced at $99.95.
