Polar Fleece
A lightweight hydrophobic thermal insulating knit that retains warmth even when damp.
Technical Overview
Developed to replace natural wool in outerwear. The micro-air pockets trapped within the double-brushed polyester pile insulate body heat while permitting vapor transmission outwards.
