I've owned an HJC helmet before. Mind you, it wasn't one of their higher end ones, just a run-of-the-mill entry level/mid-entry level helmet. Let's just say, you get what you pay for (and I've owned a lot of helmets.) Would I buy another one? Fuck no. Would I recommend it to anyone? Only if I hated them.
Despite whatever people say or online shop reviews or ratings -
fuck the Internet (my opinion included.) Everybody has their own opinions and everybody is different.
My experience with HJC was just "okay." I got what I paid for. Was it comfortable? It was at first. Did it fit? Yes. Did it fit for as long as I wanted it to? Uh, no. So it came down to workmanship and materials and I will simply summarize it as a disposable helmet. I don't think it lasted even a season. Maybe half a season at most. It was a piece of shit.
I think the more experienced riders like CharlieH and fT-z33wor will agree with this: Try on as many helmets as you can. Prioritize it by fit and comfort then cost. Buy the best helmet you can afford but also use common sense and don't take out a mortgage for one. The last thing you need is a shitty helmet that not only doesn't fit, but isn't comfortable while paying for it with your left nut.
