I've been a Bell and Giro fan for years. Did a migration to a POC Trabec on the mountain bike. Thought I would give POC a try in the road space.
Got a pretty decent deal from BC, so I thought I would order one. Measured my head (as POC seems a bit funky with their sizing) and concluded, I'm right between sizes. Perfect.
My head is a 59cm, so ordered the Medium. Fits really well for my head shape. It's about 40 grams lighter than my old Giro too. Funny how I can feel the difference on my head.
The retention system works pretty well, similar to a lobelock or noodleratchet, or bunbuckle...whatever.
The ventilation is pretty good, but I don't live where it's particularly hot or humid, so not a big variable in my purchase decision. I also wear a headsweats brand skull cap, and this helmet worked well with it.
The eyegarage (two small plastic strips in two front helmet vents) allows you to place your sunglasses to the vents of your helmet. It actually works relatively well, and glasses stay put, but obviously, the sunglass temples need to actually touch the small plastic part inside the vent. Not sure all will, so try it with your own eyewear to be sure.
The helmet strap length isn't really adjustable and the side buckles don't really move up and down the straps. That didn't seem to impact the fit for me, just an observation.
On to the helmet straps...the only thing I didn't like was a lack of attention to design details for accommodating for sunglasses. If your glasses (mine are Oakley Jawbone) go outside the straps (as they should, boyz and gurlz) they won't really stay on your face, and with a bit of jaw movement the straps will somewhat dislodge your glasses. If you place your sun glasses inside the straps, and then tighten the ratchet, it pushes the earpieces into your head just above your ears. I think that is a really poor design.
For example, look at the design of other helmets. Their straps run through the helmet and exit close to your face, so your glasses can go on the outside of the straps. If you look at a POC helmet, the strap exits in the middle of the material. This creates a big gap. (I have indicated as such on the below pic.) So your sunglasses may not go on the outside, and may need to go inside your straps. So potentially, your will fit neither inside or outside particularly well. My Jawbones are OK, but not ideal.
POC glasses had to accommodate as their temple is stepped out. Great if you want POC glasses, but they are too "monobrow" for me.
Overall a good helmet, but be sure to give it a trial run with your selected eyewear. It wasn't a complete deal breaker for me, but that type of compatibility seems like an important detail that the product managers missed.
