Daniel B.wrote a review of Smith Overtake Helmet on August 12, 2019
Familiarity: I've used it several times
I just wanted to put that out there first. The matrix they use inside the helmet retains heat from the second you put it on. I'm comparing this to my old Bell (looked like the Stratus, not sure of the exact model) helmet. If you look on the inside of the two helmets, you'll see why. The Bell helmet had a few more vents, but additionally, the inside was carved in a way to allow air to flow in and out of the helmet. The Smith helmet has a matrix that basically runs perpendicular to your head in every direction. The only vents that REALLY work are the two upfront that do not have the matrix behind them. So your forehead will stay pretty cool in those two spots, but the first time I took this helmet out, my scalp was DRIPPING sweat after 4 miles. Average effort, maybe high 70's F. Additionally, I thought it was in my head, but I noticed someone else mentioned it. This helmet creates a lot of wind noise. I usually have my cell phone strapped to the stem so I can listen to music, with this helmet, that was difficult at times.
All that being said, I decided to keep it. On subsequent rides, yes my head would still sweat but I didn't notice it as much. Additionally, I'm in Colorado and do ride in the winter. This is definitely going to be a plus in the cooler months. Also, I have to deal with cars for a portion of my ride, and although I don't like the matrix on the inside because it prevents airflow, I also see how it might be better in case of an accident. Maybe it's a better dampening mechanism than my super airy Bell that has minimal contact points. *shrugs* I'm a rider, not an engineer.
Also, on the size, I wear a Large and felt like I was at the upper end of the fit in this helmet. I think I had much more adjustment to play with in my Bell. I haven't tried it with a Balaclava yet. :|
Lastly, all the vents are blocked by the matrix, so you cannot shove your glasses in them, I was able to make my Oaks fall into the main contours but it was definitely testing their flexibility. JS
