PRIMALOFT® Insulation

Insulation technology

PRIMALOFT is a synthetic microfiber insulation originally developed for the U.S. Army. It offers an incredible warmth-to-weight ratio while being breathable, lightweight and highly compressible. 

Incorporating 90% recycled fibers made from plastic bottles, PRIMALOFT® insulation maintains its thickness and continues to retain body heat, even under pressure. This high-performance product provides the user with 38% more heat than competing insulations in dry weather, and twice as much in wet weather.
