These are expensive enough that I set them aside for especially long rides, and they are especially rewarding for that purpose. Although Assos says that these will not last especially long, I have never found any Assos product to be flimsy and still have Assos shorts that I got in 2007: you'll want to follow their directions for putting them on, washing, etc., for best results and real longevity. Watch it though--they wear out in the seat first, and I have seen Assos shorts out on the road with big patches of bare ass. Check the mirror every now and then!
The turquoise pad is controverisal, and I think it is marginally better than the old orange pad. It seems softer, but doesn't seem to be going "flat" or wearing any faster. If you prefer the orange pad, it is made by Cytech and can be found on Rapha and Search and State shorts, both are excellent alternatives. I prefer the Assos Mille shorts to both of those.
The shoulder straps are the best in the business, about 2.5" wide and very comfortable. The legs fit well, and while there have been complaints about the band fitting "loose," it tightens up well when you are actually on the bike.
The only thing I don't like about them is that there is a panel on the front made out of different material that points right at your junk and suggests a triangle of pubic hair. When your friends make fun of you (and believe me, they will), respond in a German accent that Americans are prude in these matters.
