I’ve been using Catlike helmets for about four years now. I still have the first one I bought, a Catlike Whisper in matt black similar to the one above. All the holes translate to lots of air. Even on a 100 degree day like today, the helmet was fine, even in black. I’m not suggesting black is the appropriate choice for Southern California, but it’s doable. Catlike have released a new strap system that seems to work better than before. Their sizing also seems to have changed, though that’s just a personal opinion. I used to wear a large, but now a medium is all I need. I’m curious to see if they present anything new at Interbike.
