Created by women for women as part of the RUNKOYO collection, the Asics Women's RUNKOYO Padded Vest features thermal insulation made from oyster shell material that's designed to trap and retain your body heat. Wind and water resistance adds another layer of protection against the elements and a side pocket with easy-to-reach zipper pullers provides convenient storage. Finished with reflective detailing to keep you visible in low lighting and made from at least 50% recycled materials to save resources and reduce waste.
