The women's ICON WINTER LS 1/2 ZIP TOP by ASICS is made from a brushed knit fabric that's been specially treated to lock in warmth and increase mobility. The long-sleeved top has a half zip for easy access and ventilation, and raglan sleeves for freedom of movement. Reflective Icon stripes at the shoulders and back, plus the signature reflective ASICS spiral logo, give you increased visibility, as well as helping with styling.
