Need a shirt that can keep up with your active life? This A4 Performance Interlock Shirt is built for movement. It's made from 100% polyester in a 4-ounce interlock knit, which is soft, stretchy, and ultra-tight to resist snagging. The magic is in the tech: it's designed for moisture wicking to pull sweat away from your skin and keep you cooler and drier during workouts, yard work, or just a busy day. It also has odor resistance built-in to help fight stink, and a stain release finish for easier washing. The cut is a classic crew neck with a self-fabric hem. It's a fantastic choice for gym sessions, hiking, golf, or as a comfortable, low-maintenance undershirt for work uniforms. Sizes range from XS to 2XL. It's all about function and comfort, so you can focus on your activity, not your shirt.
