Giro Air Attack, saw a member of Team Garmin riding the version without the shield during this week's Criterium du Dauphine. Almost bought that model but a local shop in Coppell had one with the shield and it fit pretty good. Shield is held on with magnets and pops on/off with ease. Feels slightly different riding without standard sunglasses but I took it out on the Collin Classic this morning and it really works great. Expensive at $240 but so far is worth it.
