I bought a Deluxe Adult Batman costume two years ago (from Amazon...it's the one with the muscle chest) and the mask that came attached to the cape was just okay. I wanted to make a few minor modifications to it and see what I could do with it. This mask goes a long way toward improving the overall coolness of the costume. It's a very realistic latex mask that covers your entire head, with two velcro closures on the back. It's fairly comfortable, but there are no ear holes so be prepared not to be able to hear too well. Being skintight latex it will also get very warm inside it after a while. The mask ships flattened out in a thin box, but retains its shape pretty well. I did stuff the ears (one wadded up plastic grocery bag each) to make them stand up straight and remain solid. After cutting the old mask away from the cape and adding this new mask to the costume, I have a very decent Batman outfit and didn't have to spend a fortune on it. I'm very satisfied with this product.
