About this style

A Fair Isle pattern lends a stylish look to this base-layer top from Sweaty Betty. It's made in a sleek slim fit with a cosy funnel neck and half-zip fastening. The seamless design helps to prevent chaffing, while the stretchy, antibacterial fabric offers comfort and freshness. Innovative HeatProtect technology regulates body temperature and wicks moisture away from the skin.
