If long days at the office or long nights studying leave you feeling somewhat less than super, perhaps you need a cape ... for your chair.

Online retailer Entertainment Earth has debuted a pair of Comic-Con International-exclusive Chair Capes (trademarked and patent pending!), featuring Bizarro and classic Batman.

They're pretty much just what they sound like: 24-inch fabric capes that attach to chairs using an adjustable hook and loop belt.

They're priced at $24.99 each, with the Bizarro Chair Cape (purple fabric with backward "S" logo) limited to 1,200 pieces, and the Batman Chair Cape (bright blue fabric with classic logo) limited to 2,400.

They can be preordered now on the Entertainment Earth website, but both will be sold first at the retailer's convention booth (#2343). Whatever remains will be used to fill and ship orders at the end of July.

Comic-Con International will be held July 8-12 at the San Diego Convention Center.
