The original UA training t-shirt was called ''Performance Grey'' and it was built from a lightweight, natural-feeling synthetic that can wick sweat and dry fast. That meant athletes could stay cooler and drier. Since that time, we've updated the name to UA Tech™, made it even softer and more comfortable, and blown it out with colors. It's the shirt that started the legacy and there's a reason you still see it everywhere.
