The sizing was spot on for me, and I am a fireplug at 5'9" and 195lbs. XL for me.
The gel leg grippers work without yanking hair if you are a quasi gorilla like me. : ) The pad seems awesome. I have only used it for club rides but I can't wait to get out for 4+ hours on it. The best part about these are the straps. Stretching but supportive, and airy-light fabric that simply vanished once on. If you have a love-hate with bibs and that suspenders feeling, these might be worth a try to swing you to to the love side.
