I have a few I rotate:
An older Shoei, forget the model, buts its ok for slightly chilly days.
When I wear a full face it's usually this though:
Doing the to and from work commute, an 11 minute ride, I usually rock a super unsafe, but somehow DOT certified half helm.
I find that you can rapidly dismiss many helmets just go down the checklist:
Does this brand make one that fits my noggin?
Do I care about carbon vs fiberglass vs plastic?
Do I really want to pay that extra for a design vs a solid color?
What is my upper limit on price I am willing and able to pay?
Just those four factors will massively reduce the selection of viable helmets and you'll usually find your left with 2 or 3 options. Personally, I don't give DOT certification any value.... zero, none, nothing, period. Any product that the manufacturer claims they test and is expected to self-police is questionable in my opinion, especially one that your life literally relies on. Snell/ECE or nothing imho, they audit companies and ensure their production helmets continue to meet the standard after certification.
Contrary to what many people may believe, a carbon helmet adds almost nothing in the way of protection over a mixed composite helmet. The area they are great in, is weight. The one above was at one point THE lightest full face on the market, it also happens to fit my head like it's custom made, and is super quiet for me, so despite the fact it was $700, it was a no brainer to buy it.
