I don't sing well enough for the aria. That seems to be equivalent to the Arai I bought. I just never got a chance to try on the Suomy. The Arai is very comfy. Where is the Suomy made? Arai is made in Japan.
suomy I'm not sure were it's made. I like the fact that is D.O.T. and BSI 6658 Type A (British Standards institution) tested. I would like to know if the inners are changable like the Aria and removable.
Made in Italy I found. Also seems like at least some models have changeable inner pieces. I think a lot of these are just a choice. You would need to take a good test ride to see if the noise levels were different, if the air flow was too much or too little etc. That's not too likely in the places I've tried to shop at. I don't think they're offering test rides in these helmets but if you could it would probably make the decision for you. Shoei, Arai, Suomy, and maybe a couple of others have excellent ratings and high prices. Some cheap ones have good ratings too. I'm honestly unsure of what it all means in the long run. The Arai that fit me was pretty plush. I may buy another one. Not yet in the market for a new one.
