Using your Hypertwenty Lockhart hoodies is easy. Just put them on and enjoy the comfort. When it's time to clean, machine wash them cold inside out with clothes of the same color. Only use non - chlorine bleach if necessary. After washing, it's best to hang them dry, but you can also 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.
