Initial impression was the fabric, especially the inserts(show black in pictures) is too light and flimsy. However I resisted the temptation to return them and after 25-30 hours on the trail and road they seem to be holding up alright, with one notable exception. The hook/loop closure under the snaps is abrading the cloth badly and it is all "fuzzy" now and will surely wear out. Definitely a design flaw. Chamois short is nice and comfortable, and my other chamois shorts fit the outer short nicely too. Venting and pockets are nice, and the shorts are cool on hot SoCal days. May update review later depending on how they wear, but I really think they should be made of a stronger material.
Cool (even in black) here in the SoCal sun, great quality, non-stink, and it dries very quickly. Quite generously sized which I like, but if you like form fitting I'd suggest dropping down a size than your t-shirt.
