Many people are hesitant to order online because of fit. Will it be too tight? Too loose? Too short? Or too long? Will it be the right cut for my body type? Is it supposed to fit like this? To help ease the uncertainty, we've put together a comprehensive fit guide. It will walk you through the various steps to finding the right UA fit for all our gear.

Under Armour® performance gear was built to be consistent with traditional sizing parameters. This means if you normally wear a "Large" T-shirt, you would also wear a "Large" UA T-shirt. So please order accordingly...and with confidence.
