At the core of what we do is our smarter Performance™ fabric. With the goal of bringing you the moisture management of a tech sport shirt with the everyday wear-ability of your favorite casual tee, we created a new way of spinning our polyester yarn to feel and look like cotton, but perform like dri-FIT polyester. Our relaxed fit, super-soft fabric prevents chafing and abrasion to feel good in any situation. This is not the skin-tight, shiny tech shirt you can only wear at the gym. Our shirts are for whatevering – wind surfing or channel surfing. -Sport Science
