I should have spoken to or chatted with a customer service rep before I bought these bibshorts. I am not a big guy...5'11" 180. (I guess for a cyclist I am big.) because I ordered the XL's based on the size chart and they were CRUSHINGLY tight. I utilized the return process (which is exceptionally easy) and got the XXL's. They fit much nicer. The straps are a little loose, but they still fit. Overall this is the most comfortable piece of cycling clothing I own. The legs stay in place, they are well vented, and the KISS chamois is outstanding. I have worn them on rides of 15 miles, 12 miles, and 30 miles and they felt wonderful. I would definitely recommend these shorts to anyone looking for a comfortable setup for their rides. Just make sure to size up before you order.
