Just replaced my Speci Prevail (EN version, sz L and 230g) with a Catlike Mixino (EN version, sz L and 240g).
Aside from an annoying strap design that would rattle against my cheeks in certain circumstances at speed, the Prevail was a fine helmet. I never had an issue with over-heating in it. I half cracked the lowest horizontal element on the front after ~3 years of me pushing it against my forehead to squeeze sweat out of my headband. (Plus I don't want any Speci gear, but that's another story.)
Before the Prevail, I rode a Catlike Whisper or Whisper Plus. It worked fine for me, but the allure of the lighter Prevail won me over. Anyhow, I'm back with Catlike after reading a bunch of positive reviews on their Mixino. First ride is tomorrow morning.
I vaguely remember this being the case with my Whisper (also sz L), but I had to open up the Mixino's retention system quite a lot to fit my dome inside it. By comparison, I had to really tighten up the Prevail's retention system to get it to stay on my head. In the mirror, the Mixino looks far more compact on my head than the Prevail. However, the Prevail is no more than 1-2cm wider and longer in reality.
