Our Transpiration T-Shirt is named after the scientific process of water moving through a plant’s stomata and evaporating into the atmosphere. Just like the plants do, this T-shirt brings in your sweat and pushes it right back into the air. This way, you can breathe. PLUS…the odor-inhibiting finish keeps the shirt smelling fresh. Perfect for those hot days on the job or that guy who never washes his uniform. (C’mon buddy! We’re sharing a truck here).
