In addition to being comfortable like everyone else has affirmed; I can affirm that I went the extra mile and tested it's performance when you go endo and land on your head. Was MTBing with some friends, hit a stump, and over the front I went. Landed squarely on my head before continuing my roll. While (naturally) I was quite dazed, I didn't have a scratch on my head and no trace of even a mild concussion. I'm definitely working through some neck, back, and shoulder injuries now... but that's not the helmet's fault. It's a good reminder that we don't wear helmets just because they're comfy. We wear them because they could save our life. The Strym did just that for me.

Was looking for a better ventilated helmet than the aero model I was riding. This helmet fit great out of the box. I have a smaller oval shaped head and it can be snugged up tightly with the rear dial. Great ventilation for an all-around helmet. It is light weight and comfortable.

I've been wearing Rudy Project helmets for over a decade -- WindMax, AirStorm and others. This is my favorite so far. I was right on the border between the S/M and the L and went for the bigger size. It fits perfectly and just disappeared on my first ride. It was on my head for 7+ hours a day during a bikepacking trip and never once bothered me or overheated. I don't know how you can ask for anything more.
