PureHero launches its first collection of cycling jerseys, BMX-inspired jerseys, and performance crew shirts based on popular Marvel Universe characters, including Spider-Man, Captain America, Fantastic Four and the Punisher.

Edit. Never mind. Looks like it never got off the ground. The press release was 3 years ago.
