Hologenix and Big Agnes have introduced the UL Recovery Sleeping Bag Liner, incorporating CELLIANT infrared textile technology. The product is designed for use inside sleeping bags or as a standalone layer in warmer conditions. It combines lightweight construction with functional material properties.
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. The product integrates infrared-generating minerals into a lightweight and washable liner intended for use inside sleeping bags or independently in warmer environments.
The Hologenix x Big Agnes UL Recovery Sleeping Bag Liner is made using CELLIANT-infused REPREVE recycled polyester. The material is designed to convert body heat into infrared energy and reflect it back to the user. This process is associated with thermoregulation, local circulation, and cellular oxygenation.
The liner is designed to be compatible with most sleeping bags and offers quick-drying and packable features.
The product aligns with broader developments in infrared-generating textiles, which incorporate minerals that convert body heat into infrared wavelengths. It also reflects a focus on recovery-oriented performance gear, combining lightweight construction with functional material properties. Additionally, the use of recycled-performance fibers highlights the application of sustainable materials integrated with functional additives.
These developments have implications across multiple sectors. In outdoor recreation, sleeping systems and camping equipment are incorporating regenerative textile technologies. In athleisure and recovery wear, apparel is being designed with infrared or bioresponsive materials. In healthcare and physical therapy, such textiles are being explored for use in products aimed at supporting circulation and oxygenation.
