Sorry to be boring but I actually bought some Women's Castelli tights (the shorts I only tried, the tights I actually bought 2 of) this winter, I think the Paolo Pezzo chamois is in them, they are absolutely superb, light, warm, they breathe, not too hot when it's not actually too cold, but really warm when it is quite cold,they are wonderful (but a little expensive). Beware I also tried on some Castelli knickers which had a large red chamois in them, this was much bulkier and I think would have been much less comfortable, no way way I going to buy those. The chamois in the shorts I liked is the same as the one in my tights, sort of "Y" shaped and when you wear it, does not have lots of extra cloth flapping around, just perfect, personally although expensive I think that Castelli chamois is worth the money whatever garment you find it in...
