I found that the Protera+ fit comfortably around my head. The retention system cradles the skull a little lower than some helmets, which didn’t bother me during testing. It’s a cinch to tighten the rear RSR9 retention dial one-handed. I found that the visor screws are pretty low profile and were pretty difficult to adjust, but I appreciated that the screws never came loose during our test period.
A highlight for me was the Airframe design and ventilation. During long hot climbs in Southern California me head remained cool and I could feel the air circulation through the helmet.
Depending on the type of glasses you wear, you could have some issues with the retention system. Some of my “action” style glasses from Oakley and Smith had issues tangling or contacting the system a bit. I found that my lifestyle sunglasses fit the best because they have shorter arms.
Overall, I really like the helmet in terms of fit, looks and functionality. It’s a very spendy helmet to not have MIPS or another rotational impact protection design. At first the narrow visor was a bit of an issue for me, mostly from an aesthetic perspective, but over time I adjusted to it. If you’re looking for an alternative to the major players in the helmet game and kind of like that Euro-style flair, the Rudy Project Protera+ could be worth a look. It feels nice on my head and has some nice features like goggle or sunglasses retention and the Strap Quick Change that make it pretty cool and stand out at the trail.
