Under Armour rocks. It's definatly well worth it. I own several pieces of Under Armour gear. From shirts to boxers. It's all well worth it.

Several companies make knock off versions for less money. The knock off versions work, but seem to wear out quicker and aren't as comfortable. They even sell the knock off versions at Walmart and Target.

Pick up a few pieces of Under Armour gear and a few pieces of the knock off gear. Wear both and see what you like better.

From my experiences, I'll stick with the Under Armour.
