A hard-working midlayer that performs every time, the MILLENNIUM YAKWARM Half-Zip Long-Sleeve Top is an essential choice for active women seeking bigger and better running challenges this winter. Crafted in a highly-technical blend of yak wool and polyester for ultimate warmth and softness, the top uses organic body-mapping to guarantee optimum temperature regulation and freedom of movement. The half-zip offers additional ventilation when you need it and the natural fibres in the fabric also minimise the build-up of unpleasant odours, which is ideal when you’re running hard and working up a sweat even in the cold. Finally, reflective details keep you visible in low light. Banish the chill and stay active all winter long thanks to the MILLENNIUM YAKWARM Half-Zip Long-Sleeve Midlayer Top by ODLO.
