Had many bikes, and many lids. However, I have a oddly big head for helmets, and most are uncomfortable or just do not fit.
The most comfortable helmet I have ever tried and owned was an Arai Quantum. It was like your most comfy sofa to sit in ! The lining in side was soooo plush too. Problem though was noise just was not great. Oh, and was about £500 in 2007 so I dread to think how much the equivalent would be now !
Only other make that fits me well is Shoei, so went for a Neotec 1. Still got it now and love it (about 3 yrs I think so far).
Next time I get a new helmet, I'll try them all again as manufacturers do come up with new shell shapes every now and then. I'll probably go for one of these lids you can flip and still legally ride with (like the wifes LS2 Valiant) if I can find one to fit me !
