Well constructed turtleneck pull over, sleeves feature thumb-holes, very long back, high, elastic turtleneck. The zipper is lined so that it does not touch the skin. TermoSwed Plus is an extremely high-quality, two-layered undergarment with excellent fit. The fine rib polypropylene terry cloth inner absorbs moisture and wicks it away from the skin. The cotton outer absorbs the moisture and moves it on to the next clothing layer (e.g. fleece). This keeps the body warm and dry. The fabric weighs 275g/sqm and is made of 66% polypropylene, 25% cotton and 9% nylon. Tested by the Textile Research Institute Hohenstein, Test-No. 87.4.1536.
