I got this in from Italy, and went a size larger then usual thinking it would run small. Turns out with all the stretch panels in leather & textile for movement and airbag deployment it runs about a size large. I take a 54 in Rev'it/ Dainese jackets with a close fit, and this thing is about one numeric size large feeling on me. Features wise, this competes with the top jackets from Dainese / A* - very similar to the GP Tech jacket I had at one point. Tons of perforated stretch leather, segmented micro perf all over, kevlar overlays at the forearm seam, and a single panel of stretch fabric running from the top of the shoulder all the way down to the cuff. BETAC armor at the joints, 3D mesh back protector pocket, vented race hump. $435 shipped.
