Warm & breathable Arctec 240 fleece will keep off the chill year round. Wear it over a light base layer for cool summer days or layer it up under an insulated jacket in winter. It effectively traps your body heat & allows perspiration to escape so you stay dry & temperate in the outdoors. Its flatlocked seams are comfortable against your skin & the elastic bound hem & cuffs with elasticated cord thumb loops keep out drafts. This is your must-have fleece.
