Mancave A man cave is very important for guys because it’s a great place to relax and hang out with friends. It’s also great for women because the man cave is where men can store their toys and gadgets that women may not prefer to be out in the home. A man cave can be designed in many ways. It can be covered in sports paraphernalia, it can be a movie theater, or it can be an arcade with games like shuffle board and PacMan. What do you keep in YOUR man cave?
