Familiarity: I've used it several times
I hate having things on my head. I would ride w/ no helmet if it weren't asking for brain damage. I love the Evo because I can almost forget I'm wearing a helmet. It's light and unobtrusive. You really notice when turning your head from side to side. You don't feel the "swing" you do with other helmets. It also vents extremely well. It does all of this because it is built like a mountain bike helmet. Other high-end helmets I've owned or compared are far more like my motorcycle helmet; lots of cushy insulation, thick protective shell, etc. Those other helmets are probably marginally safer in a crash. But, I plan to spend a lot more time riding than I do crashing. And the Evo would probably be a single-crash helmet -- wreck and replace. If you're the kind of rider looking for a helmet "in case" you crash, buy the Evo Carbon Camber. If you're a rider looking for a helmet "because you will" crash, maybe stick with a TLD D3. Fitment is good, maybe a tad big. I wear a large D3, and a medium in older 661 helmets. I ordered a medium in the Evo Camber. I'm happy with the fit, but it could be just a smidge tighter. If you're between sizes, definitely go smaller. My only knock on this helmet is the carbon lay-up. It could be done better. There is an obvious seam along the center line of the helmet and where the chin guard connects. You can't see it from 2 feet away, but carbon is meant to be oogled over. I have to subtract a star for that reason only. Otherwise, the finish is fantastic. The fully removable liner is really nice, too. No matter how breathable, you're still gonna sweat. I paid over $200 for my Evo. It was a great deal then. It's a no-brainer at the current price!
