Crazy

Men's Thunder T-Shirt

<p>The Crazy Thunder T-shirt is extra thin, lightweight and breathable, making it ideal for running on very warm days. <p>Because that's what it's designed for: intense mountain running on warm, dry days. The fine, laser-cut air vents under the arms, on the sides and in the chest area allow air to circulate and sweat to evaporate. Thin hems and an overall technical but otherwise very minimalist design make this running shirt extremely light and comfortable.
