The Pearl Izumi Men's P.R.O. Air Bib short has the lightweight feel and the compression I expected of bib in this price range. I consider it a perfect bib for longer rides 2-4 hours on warmer days. Worth the price.
I like the fit and will probably continue to buy more bib shorts in the future.
I bought the 2XL and it was too big. 5'10" 177lbs Athletic. XL was perfect and it is a comfortable ride experience from the first ride.
