These Zascanauta hoodies are super easy to use. Just put them on and go! Whether you choose the zip - up or pullover style, you'll feel comfortable all day. When it comes to washing, remember to turn them inside out and use cold water. Wash them with similar colors to prevent color bleeding. Only use non - chlorine bleach if there are tough stains. After washing, hanging them to dry is the best option. But if you're in a hurry, you can tumble dry on cool or low heat. Don't use fabric softener because it can make the colors fade. Also, avoid ironing and dry - cleaning to keep your hoodies in great shape.
