Hologenix, the materials science company behind CELLIANT infrared textile technology, has partnered with outdoor equipment brand Big Agnes to introduce the UL Recovery Sleeping Bag Liner. This product incorporates infrared-generating minerals into a lightweight, washable liner that is intended for use inside sleeping bags or as a standalone layer in warmer conditions.
The performance-driven Hologenix x Big Agnes UL Recovery Sleeping Bag Liner is constructed with CELLIANT-infused REPREVE recycled polyester, which converts body heat into infrared energy that is then reflected back to the user. This functionality supports thermoregulation, local circulation, and cellular oxygenation.
The product is positioned to fit most sleeping bags. It also offers quick-drying and packable properties, which will give outdoor enthusiasts peace of mind.
