Without a doubt the best sports top I've ever bought. The quality of the fabric is excellent no matter what. It's really breathable and feels great against the skin unlike other sports tops which can be sticky. I bought one thinking I already had a few tops but now I don't want to wear anything else and will be buying more. I can see this top will last forever. Torn to pieces! (Now please start making them in multipacks) oh it has breathable sidewalls too. They are precise as they don't have any annoying notches on the inside. Really comfortable.
