To put together this all-season quarter-zip, tasc took the jersey-knit organic cotton and bamboo fabric they use on their active shorts and workout tops, and knit it into a track-ready zip up made to move. The fabric's moisture-wicking, anti-odor, and super breathable, too — plus it'll give you UPF 50+ sun protection for days spent outdoors.
