Wow..oh man i busted up reading about this one. There is a company out there that makes this awesome thing called The ThermaJock.
I spotted this on Urban Velo. I couldn't tell if it was a joke or a serious product. I browsed around and read the testimonials to which there were no puns I could quote, but in all truth the cold season is upon us and I really wonder if this product truly withstands to the test of nature. I'd give it the good old college try, I wonder what it looks like under bike shorts..haha.
