Using these Soulkr hoodies is simple. Just put them on and enjoy! For sizing, pick from S to 4XL to find your perfect fit. When it comes to washing, use cold water and turn the hoodie inside out. Wash it with similar colors to avoid color bleeding. Only use non-chlorine bleach if really necessary. After washing, you can hang it to dry for the best results, or use a cool or low heat setting in the dryer. Don't use fabric softener as it can make the colors fade. And remember, don't iron or dry clean these hoodies to keep them in good condition.
