DetailsLasting Size Chart The Wiry sweatshirt is sweatshirt made of 100% sustainably sourced Australian Merino wool. It has a zip collar and a two-layer smooth knit made of the finest fiber, therefore the material will not scratch or itch. Flat seams and cuffs with thumbholes enhance wearing comfort. A double insulation layer in back adds extra warmth. The wool is highly antibacterial and ensures moisture wicking, so you will still feel dry and odor free even when you sweat. Recommended as a second layer for winter sports and casual wear.
