Great product I enjoy wearing these every time I ride. I will purchase more of them, just for spares. The fit is good ( I am 5,9'' and 160 lbs, and I ride an F800gs). They help the most on long rides where I get hot spots on my tail bone. With the addition of these boxers and I have recently changed seats, so i think I have solved the problem! August 10, 2013
Excellent Riding shorts AWESOME! I was not a fan of riding shorts but friend of mine told me to get some. Selected these after viewing your video as a test. I have to say I am now a firm believer in riding shorts. These are nothing short of outstanding. In temperatures above 100 these worked as advertised. Kept the rear cool. Only minor thing is the elastic band could be beefed up a bit but other than that; just a great product. A must wear for any ride. July 9, 2012
Great Shorts!! Airy and dry. I forgot I had them on. Great product!! Airy and dry at the end of 440 miles I forgot I had them on. Once I remembered, I wasn't even in a hurry to get them off either. RevZilla is the bomb! June 4, 2012
