At Arborwear, we don't believe in the “if it isn't broken, don't fix it” mentality. We are always looking for new ways to improve our products. That's what led us to develop the Tech Single Thick Sweatshirts. We've taken our wildly popular Single Thick Sweatshirt and made it out of performance fabric that is 33% lighter, wicks moisture, holds its color and has a Teflon fabric protector to help keep you dry and repel oils & stains.
