If you're a fan of Superman, Batman, Ironman, Captain America, The Hulk, or Spiderman, then Under Armour's Alter Ego Compression Shirt might just be the thing for you. It's made with HeatGear® technology that essentially keeps you dry, cool, and light during your workout sessions. Wear them as a standalone shirt, as a baselayer, or even as a halloween costume. If you don't want a tight fitted shirt get one size up from your true size.
