Sugoi is still my favorite for hot weather -- RS or Evolution -- but I also have a pair of Assos which I got on special a while back, and they are pretty awesome in hot weather too, and they have a nice flat waistband that sits just below the waist and doesn't press. But either they run a little small, or I am running a little big. I wear medium in Sugoi or other brands, but the Assos medium are just a little snug, and I have to yank them up from time to time because that low waist slides down over my stomach.
