When the pressure's on, your performance gear needs to keep up. This adidas base layer is built to keep you locked in on the baseball field. A breathable polyester build with added stretch and three-quarter length sleeves lets you move comfortably without restrictions all over the field. Whether you're warming up on the infield or stepping to the dish for the game's biggest at-bat, this base layer has you covered. This top was made using UNITEFIT — an all-gender fit system that was created with a spectrum of sizes, genders and forms in mind. This product is made with 100% recycled materials. By reusing materials that have already been created, we help to reduce waste and our reliance on finite resources and reduce the footprint of the products we make.
