These adult bushy brown prehistoric caveman wigs are a great accessory for 100s of costume themes from the cave men, to Viking raiders, barbarian hoards, and more! These are 100% synthetic wig sets, can be washed, and can be worn without a wig cap although wig caps may help depending on how much hair you have. Great on their own, even better with the other caveman and barbarian costumes and accessories in our store!
