The World's Best Synthetic Insulation

PrimaLoft®—Insulation Technology

PrimaLoft® insulation is an integral component in products that provide warmth and comfort from head to toe, and is warmer, drier, softer and more compressible than all other insulations.

PrimaLoft® has products to meet specific needs for outdoor enthusiasts, sportsmen, and the military. Learn more about the PrimaLoft® product for your specific application.

PrimaLoft® is WARMER

The proprietary ultra-fine fibers of PrimaLoft® insulation form a tight collection of air pockets that trap heat from your body and keep the cold out, providing an excellent warmth to weight ratio that keeps you warmer.

PrimaLoft® is DRIER

When insulation gets wet it loses the air pockets and insulating properties. PrimaLoft® ultra-fine fibers were developed to be water resistant to stay drier and maintain insulating properties. The fine fibers create a tight surface tension that won't allow water to pass through the insulation. Specially developed fiber finishes repel water and keep the insulation drier even if water is forced into the insulation.

PrimaLoft® is SOFTER

Fiber diameter directly influences softness. If you compare canvas fabric to silk fabric, the finer silk fibers result in a softer material. PrimaLoft® fibers have been engineered to be ultra-fine and mimic the softness of goose down.

PrimaLoft® insulation is made with ultra-fine fibers which make it more compressible. Compare the two containers, one with only 10 feet of climbing rope, the other with 160 feet of dental floss. The finer dental floss is much more compressible than the climbing rope!
