With UFC 99 in Germany, I looked everywhere I could to find MMA lederhosen for anyone headed to Deutschland. Alas, Tapout, Silver Star and Cage Fighter have yet to expand into the traditional German clothing market. So, if you're an American in Cologne, you may as well show off your patriotism.
Europeans think that all Americans are arrogant anyway,* so we may as well own it. You can buy either hat for just under $30 at Tapout.com.
*Sweeping generalization made for effect.
