Using this cap is super easy. Just adjust the size to fit your head comfortably and put it on. You can wear it in any situation, like when you're going for a walk, running errands, or at a sports event. When it comes to maintenance, you can machine - wash it on a gentle cycle with cold water to keep it clean. Don't use bleach as it might damage the tie - dye pattern. After washing, reshape the cap and let it air dry. Avoid leaving it in direct sunlight for too long to prevent the color from fading. And that's all you need to know to enjoy your new cap for a long time!
