I went from an AyR8 to a Kask. This was nearly 8 years ago and unsure how much CO has changed helmet shape during the last few years, but if you’re still shopping it might be worth keeping in mind. The price is a bit hefty so I do try to buy on sale (helmet week, Boxing Day, Black Friday) and can usually find it for 20% off.
I recently-ish repurchased a Kask as my old one hit the 5 year mark (technically a little bit longer than that but I dragged my feet on purchasing), and they changed the shape slightly. Still fits my head but thought it was super weird - why change the shape of a helmet?
