To use your Bat Joke hoodie, just put it on like you would any other hoodie. It's great for casual outings, lounging at home, or as a layer during cooler days. When it comes to washing, use cold water and a gentle cycle. Don't use bleach as it can damage the design. Hang it to dry or use a low - heat setting in the dryer. Avoid ironing directly on the design to keep it looking good for a long time.
