So, there’s no delicate way to put this: Hot Classes make you sweat. Sweat makes you smell. And smelling isn’t high on our priority list, so we created the UA Hot Class Collection. It’s built with an odor-fighting technology to keep your gear smelling fresher, longer. Pair that with our soft, stretchy, super-supportive UA StudioLux® fabric, and you’ve found your new favorite gym buddy.
