Comfort and Secure

  • Familiarity: I've used it several times

Full face is new to me. I expected air-flow issues, fogging, maybe hot? Not with this helmet. Everything you've read in the other posts here? true - light, comfortable and stays put on pumpkin. I have an XL/XXL POC XC Helmet and the XL is perfect.

Great helmet!!

  • Familiarity: I've used it once or twice and have initial impressions

This helmet is not overly heavy and has great side vision. My medium weighs 980 grams, almost exactly 3 times my Fox Striker, but much, much safer.
I agree with Nathan below, If in doubt go smaller. I am right at the very top of the medium chart and was a little worried since my head is kind of round, but the medium fits fantastically.
Also, in case you haven't dealt with Backcountry before, these guys are AWESOME! My helmet came in 1 1/2 days to N. CA. Very happy with this webstore!
One reviewer below talked about the carbon layup at the back of the helmet. Yes, it could have better workmanship; you can see sort of a frayed edge seam, but it isn't horrible. My guess is this is one of the reasons it is so cheap now. For the price, I don't see how you could not buy this thing.

MTB, not Moto-X

  • 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!

If my size is right at the top of Medium,...

If my size is right at the top of Medium, should I get a M or L?

Great helmet at a great price

  • Familiarity: I've used it once or twice and have initial impressions

I recently purchased this helmet. It's my first full face helmet. I like the fit, the ventilation, and the weight. Still got warm during a full day ride in the sun, but I think that's pretty standard.

Confidence insipiring

  • Familiarity: I've put it through the wringer

This fits very well, offers exceptional visibility, and is so light that I frequently opt for it when only a full coverage XC helmet would suffice. I feel very protected and mobile inside it.

I can only say that I have experienced some chatter on the mounts for the visor, but this does not take anything away from its function in protecting a head.

Looks really cool, and its super light. However, I ended up sending it back and getting a fox helmet, as the fox one fit my head better (tighter on the face/cheeks).
