The hollow-core yarn construction creates a lofty, air-trapping structure that provides insulation without the density of traditional fleece. During intense output, this open, zig-zag knit works like a radiator, dumping excess heat and moisture to prevent that clammy feeling. This makes it a specialist tool for athletes who need insulation during rest periods but maximum ventilation when moving fast, a balance that conventional fleece often fails to achieve.\u003c\/p\u003e \u003cbr\u003e \u003ch3\u003eFabric\/Material Composition\u003c\/h3\u003e \u003cp\u003eThe body is constructed from 5.7-oz 100% recycled polyester jacquard fleece with hollow-core yarns and treated with HeiQ Fresh durable odor control.
