Technology Jack Wolfskin PRIMALOFT®

Information

PRIMALOFT® are thin, soft fibers that create a perfectly durable synthetic fiber filling that can withstand washing and the stress of a variety of activities. The fibers are significantly finer than other synthetic insulation materials, which allows them to hold more air and can be compressed into a smaller volume. For that reason, they are very often used to fill insulated jackets, as they resemble down.
