These Airbending University hoodies from Typhoonic Art are really cool. Whether you choose the zip - up or the pullover style, they're comfortable and stylish. When you wear them, just zip up or pull them on like normal hoodies. For cleaning, put them in the washing machine on a cold cycle and turn them inside out. Wash them with clothes of similar colors. Only use non - chlorine bleach if it's really dirty. After washing, it's best to hang them to dry. But if you're in a hurry, you can tumble dry on cool or low heat. Remember, fabric softener can make the colors fade, so don't use it. Also, don't iron or dry clean these hoodies to keep them in good shape.
