In my old view of the world, "Under Armor" and "Tennis" should never be in the same sentence. But I have I would be lying if I told you I did not like the Under Armor apparel this year. And it is for exactly the opposite reason I thought I would hate them in the first place. I figured a company best known for its football clothes would bring more bad styles to tennis. Boy was I wrong.
Under Armor has effectively merged the modern with the classic. This is what makes Nike's apparel so darn great, and its what has won me over. As much as I'm an old-school, let's keep some tradition in the game kind of guy...I'm not in any way against technology, modern looks, etc. I just don't think tennis players should look like they're trying out for Cirque du Soleil.
Under Armor's apparel have classic cuts and traditional looks, with a twist. Very cool colors, unique treatments of stripes and the technology that has made them famous. All tasteful, functional, and cool-looking. Good job guys, and apologies for doubting you.
Tennis Warehouse has a great Under Armor selection
