So the new SGH releases are definitely more along the lines of old school releases. Nothing super flashy just great styles that people expect from Oakley. Square Wire- similar to past releases and no spring hinge. Great fit. Valve- love the fit. Feels like a pair of old Straight Jackets M2- again loving the fit. So light and not quite as tight to the head as Radar. I do love my Radars but these feel great.
