Danelle Folta (Captain)
Two years ago, these three Playboy Playmates proved they were a force to be reckoned with as they battled both stereotypes and the brutal jungles of Borneo. Now these centerfolds are back - and out to prove that their finishing an Eco-Challenge wasn't just a fluke. Driven by gritty determination, and led by a brilliant mountain man from Alaska, the team will stop at nothing in their quest to cross the finish line as a ranked team.
