UA Tech is our original go-to training gear: loose, light, and it keeps you cool. It's everything you need. UA Tech fabric is quick-drying, ultra-soft & has a more natural feel. Material wicks sweat & dries really fast. Anti-odor technology prevents the growth of odor-causing microbes. Many UA Tech T's are made with recycled, traceable polyester & re-use about 5 bottles per shirt.
