The original UA training T-shirt was called “Performance Grey”. Built from a lightweight, natural-feeling synthetic that can wick sweat & dry fast, it allowed athletes to stay cooler & drier. Since that time, we’ve updated the name to UA TechTM, made it even softer & more comfortable & added a range of colours. It’s the shirt that started the legacy & there’s a reason you still see it so often.Features:UA TechTM fabric has a softer, more natural feel for unrivalled comfortMoisture Transport System wicks sweat away from the bodyAnti-odour technology prevents the growth of odour-causing microbes
