The Best Choice for Damp, Wet and Cold Weather
Developed for the US military for use in clothing and sleeping bags, PrimaLoft is a down-like insulation that mimics the lightweight compressibility and warmth of down, but continues to insulate even when wet. It has a supple hand that drapes comfortably for activewear.
Compressible – easy to pack. Similar to the structure of down with incredible softness, PrimaLoft is highly compressible and easy to stuff. Its resilient fibers are quick to regain their loft to provide uncompromised insulation.
Soft – comfortable PrimaLoft insulation is flexible like down, making it an excellent choice for active outerwear. It allows unrestricted movement and its light weight makes it comfortable for extended wear.
Easy care – hypoallergenic and easy to maintain. Machine wash in cold water on gentle cycle and tumble dry. Remove promptly to ensure maximum loft. Be sure to read the care label of your specific garment to protect other construction fabrics.
