I've been using the AGV K3 SV for a few weeks now and I must say so far so good. I like how the padding is very soft and is pretty well ventilated, the fit is snug but can feel tight at times, I like the tight/snug feel of so it's not a issue for me. The Sun Visor, is a nice feature - just flip the switch and down comes the visor, no need to swap shields or have sunglasses. It's not the lightest, but it's not the heaviest either. For the price you are getting one very nice helmet with high end features for everyday ridding and not to mention a slick mean looking helmet.
