Anyone have the 509 r4 helmet? How do you like it? Any fogging issues without plugging it in? I've always had the AF-2 helmet with no electric shield and never fog. But... it's getting challenging to find replacement parts so was thinking of trying something new. My son got a HJC I believe and the thing fogs between the duel lens.(dealer replaced the lens two times already) Would prefer not to plug in but if that's the only option now a days I'd venture down that road. I really only trail ride. (My apologies if this chat was in a previous post) Or perhaps any other helmet recommendations would help. Appreciate your guys input. Thanks
