The UA HeatGear Armour Asymetrical men's single leg training leggings were created for players recovering from knee surgery (or aiming for preventive measures) to give them a comfortable aid under their protective gear that is a step up from less functional leg sleeves. Made in one-piece, you won't have to worry about your sleeve falling down and still receive targeted muscle support and joint stability you need. Plus, single leg compression tights are a fashion statement you can make on the football fields or the basketball courts.
