    Recovery gear used to be the preserve of elite athletes with sponsorship deals and physios on speed dial. Big Agnes' UL Recovery Liner brings bioceramic technology to the rest of us mere mortals who still wake up sore after a big day on the hills. The secret is CELLIANT fabric – a blend of bioceramic minerals that captures your body heat, converts it to infrared energy, and reflects it back to improve circulation and cellular oxygenation. The science has been properly tested and proven to support temperature regulation, promote restful sleep, and speed recovery. Which means you wake up feeling less like you've been put through a tumble dryer and more ready to tackle another day. At 310g, it's light enough for backpacking trips where every morning matters, and the soft woven fabric feels genuinely comfortable against your skin rather than like you're wrapped in a survival blanket.

      • Integrated CELLIANT bioceramic fabric scientifically proven to enhance recovery
      • Converts body heat to infrared energy to improve circulation and oxygenation
      • Supports temperature regulation for more comfortable sleep
      • Soft woven recycled polyester construction
      • Reversible to fit right or left-zip sleeping bags
      • Packs to 20 x 11 x 8cm in included stuff sack
    • Regular Long

      • Fabric: Recycled Polyester CELLIANT® Fabric
      • CELLIANT Fabric contains a natural blend of bioceramic minerals that captures and converts body heat into infrared energy and returns it to the body
      • Polyester stuff sack with liner fabric end cap
      • Recycled Materials: made from recycled polyester
    • Big Agnes is a small, independent US outdoor brand out of Steamboat Springs, Colorado – a small ski-town that we’ve never visited but which we like to imagine is full of mountain-loving, trail-hiking outdoorsy types. That would make sense, since the company makes some of the best ultralight backpacking gear around, including the award-winning Copper Spur, Tiger Wall and Fly Creek tents. It is kit that has clearly been designed by a gang of folks who love sleeping in the dirt just as much as we do here at WildBounds.

      Oh, and if you’re still wondering where the heck that name Big Agnes comes from, we did try to find out. Depending on who you talk to, it’s either an affectionate tribute to a legendary truck drivin’ mountain mama, or a 12,000 foot peak in the Mount Zirkel Wilderness. We kinda like the first one better.
