Safety is clearly the driving factor behind the 6D’s design, but the safest helmet in the world doesn’t do much good if it’s miserable to ride in. Fortunately, I actually find the 6D to be well put together and pretty comfortable.
The 6D has a dial adjust fitment system that’s pretty similar to that used in most other helmets on the market. It has a 3 position height adjustment, and with a bit of tweaking, it cradled my head really well and stayed put nicely on rough trails.
The straps are fantastic – they mount to the sides of the helmet so they lay nice and flat, and they still have an adjustment near the ear to get the fit right. The straps have a “Fidlock” magnetic buckle that I’m still on the fence about — on one hand, it’s easy to use, and especially when wearing gloves, it beats a traditional buckle. On the other hand, it kinda feels like it could pop open in a crash, which is obviously a concern.
The 6D’s visor is nicely adjustable, and it’s pretty big. I think the look of it matches the helmet well, but fans of smaller visors (or no visors) might not like how it looks.
Initially, I’d sort of assumed that the helmet’s design would make for crappy ventilation, but it actually does pretty well. It’s not the coolest helmet I’ve ever worn, but the venting gets the job done adequately – I’d call it fairly average in the category of “more protective helmets.”
The 6D manages sweat really well – the padding inside the helmet keeps everything comfortable, and an extra wide pad across the brow does a good job of keeping sweat out of my eyes.
While there are a few aspects of the 6D’s safety offerings that can be speculated upon, based on my highly unscientific but nevertheless critical assessment, 6D makes a compelling case. I have a lot of helmets sitting in my garage, and some of them beat the 6D in terms of breathability, attaching gadgets to my head, or some other non-safety-related measure.
But if I’m going to take a huge crash that involves landing on my head, out of the all the helmets I’ve tried, the 6D would be the one I’m going to reach for. The safety features are simply above and beyond anything I’ve seen offered in any other helmet.
