We had many options when determining which manufacturer/fabric to use when we picking our shirts. We choose Sport Science for the simple reason that they work. We've even worn them on our 50k runs without a single complaint. Be warned though, if you wear these to either races or expos, you'll receive plenty of "cool shirt" comments. sport science™ products work hard while you play. This is how:

Hydrate your insides, not your outsides. sport science™ products are engineered to keep you dry because that means staying cooler when it's hot and warmer when it's cold. Our dri-release® fabric rapidly wicks perspiration off the surface of your skin, moving it through the fibers and into the air. Not only does this keep your core body temperature steadier, but a dry shirt is lighter and more comfy than a wet one. Relax. All sport science™ products are machine washable and dryable. Plus, they won't pill like other polyesters, and they'll stay wrinkle free. Enjoy. sport science™ products are designed to fit and feel good in any situation. From our super-soft fabric with a higher thread count on the face, to the seamless body construction, to the heat-seal labeling, we make sure each product prevents chafing and abrasion down to the last detail. Take a whiff. All sport science™ smarter basics™ are treated with a special FreshGuard® application in the spinning process to reduce odor buildup in the fabric. This should help keep you and your locker room or gym bag from smelling like a locker room or gym bag. 85% Polyester - 15% Cotton
