Since B.J. Penn is fighting on Halloween weekend, RVCA, his longtime sponsor, came up with a shirt that's perfect for the holiday.
It's perfect if you're going as an MMA-loving skeleton, or as a skinny Penn fan, or as someone who loves Hawaii so much that you want to wear it on your shoulder and you don't mind being dressed as a skeleton. Buy it for $29.99.
