Whoa, this heather green 60% cotton 40% polyester Big Bang Theory Green Atom Zip-Up Hoodie is really nice and gives the ol' tip of the hat to the hit television series the Big Bang Theory! With stripes on the arms, a zipper up the center, and an atom symbol across the chest even Leonard would be proud to wear this awesome hoodie! Matter of fact, doesn't he wear something very similar to this? You can get the Big Bang Theory Green Atom Zip-Up Hoodie and you'll practically be a part of the gang. Just remember where Sheldon sits - he doesn't like when people steal his seat!
