The Superman Light Blue Peruvian Cap has a 100% polyester lining and a 100% acrylic shell but the real question is...will this great peruvian style beanie grant you super powers? Unfortunately not and I have to tell you - it use to! The thing is about super powers is that people tend to go drunk with power; we can't even trust people to go get pretzels with the company credit card without them coming back with puppies or one of those moon-bounce thing-a-ma-jigs. So I guess we just need to settle with the exceptional symbol and the tassels on the Superman Light Blue Peruvian Cap!
