The ASICS Women's X 1/2 Zip LS Top is a stylish twist on the traditional half-zip long sleeve with an asymmetric zipper. Zip it down for ventilation, or keep it zipped up for maximal coverage and warmth. Two zippered hand pockets provide ample secure storage space for small essentials. Thumbholes at the sleeves provide sleeve security, and the fitted construction gives this top a sleek look. With a reflective detail at each cuff in back, you will be more visible in low-light conditions.
