Crewneck 200 is a base layer top designed to be worn next to the skin, or alternatively as a second layer in cold conditions. It is circular-knitted and has no lengthwise seams, just like the other garments in the same range. Seams can chafe the skin and are also the weakest link where a garment can break. The sweater is made from Woolpowerâs own fabric Ullfrotté Original 200, which insulates body heat effectively and keeps you warm. The back is longer to prevent gaps between the top and the bottom. The neck is round, and the cuffs are knitted into the ends of the sleeves.
