Whether you're hitting the gym, riding a motorcycle, or just need a lightweight layer under a helmet, these polyester do rags (or skull caps) are super handy. You get a 2-pack in classic black and grey, so you always have a clean one ready. They're made from a soft, breathable, and quick-drying polyester fabric that pulls sweat away from your head, keeping you cooler and drier. They're super lightweight and stretchy for a comfortable, snug fit that won't slip around. The double-layer brim and adjustable strap in the back let you get the perfect fit for your head size. They're multipurpose: wear them as a simple skull cap for sun protection during sports, use them as a liner under a bike or construction helmet to absorb sweat and add comfort, or use them as a head wrap for a casual look. They're easy to care for – just toss them in the washing machine. A practical, affordable accessory for athletes, bikers, or anyone with an active lifestyle.
