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

Made in the USA with the highest level of quality and craftsmanship by fairly paid workers. Since 2008 Sport Science has stayed committed to keeping our product American-made, from the spinning of the yarn down to the printing and shipping to the customer – giving us the ability to respond rapidly to customer requests with the highest level of quality control. -Sport Science

◊ Note-> Many of their products are manufactured in the USA - but their line of PolyBlend items is not manufactured in the USA.
