Polyester fleece has proven itself to be highly functional with many advantages. It’s lightweight, high loft, picks up very little water and dries fast. It is also very easy to care for. The biggest drawback of fleece is wind resistance. Not so with 4X Microfleece™. It features a unique knitting process that makes it up to four times more wind resistant than traditional fleece. It is the ideal choice as either an insulation layer or an outer garment in cool, dry temperatures as it greatly reduces heat loss through wind penetration.
