For the Mature Woman - Dynomite.
Had to go through a couple pair of other Castelli Woman tights to get to this one, but its the pick for the girl who likes support, quality, no pinch, but rides you like a nylon stocking. No butt creep at all on this fine quality item. These have safety reflectors and a wonderful Kiss line Chamois. Hey, I'm her husband, and I know how to treat my lady to the best. I'll probably die trying anyway.
And special thanks to the Fantastic Support from Real Cyclist, I found all of their folks to be Top Notch.
Something about an Italian cycling pant made in China, though? Such is the way of the world.
