This 1/2 zip top is a versatile cold-weather running garment that's designed to help runners keep warm in colder conditions. The top implements a higher neck design to help shield the wind. Additionally, strategically constructed details, like the chin guard, protect the skin from zipper closure. Meanwhile, the front zipper allows the runner to unzip and experience better ventilation. This 1/2 zip top also has a reflective ASICS Spiral logo to help increase visibility in low-light settings.
