What we have here is a high-quality training top by Mizuno, which was dubbed Pro Breath Thermo. As its name suggests, the product incorporates lightweight Breath Thermo fabric technology, which makes use of escaping body vapor in order to generate heat. Pretty cool, right?
The top also comes with Mizuno Performance neck taping and Mizuno Runbird heat transfer system on the left lower sleeve, and we should also mention the Runbird only logo heat transfer on the front part of the neck. This product was designed for training use, and it was manufactured using 79% DryLite® Polyester with 19% Rayon and 5% Breath Thermo Polyacrylate.
