Helmet Shape Bias

Different brands fit different head shapes:

CP fits best on neutral to round heads.

Kask leans slightly narrow but is very comfortable.

Atomic is great for longer, oval-shaped heads.

Wearing Glasses Under the Visor?

All three brands accommodate glasses—but only CP allows you to adjust the visor spacing using removable foam inserts for a custom seal around the nose and cheeks.

Need to Adjust Mid-Day?

All three use glove-friendly dials. CP’s Size Adapting System and Atomic’s 360° Fit System are easiest to tweak on the go.

Comfort vs. Compression

CP offers precision control without pressure.

Atomic offers a full-head "hug" thanks to Live Fit foam.

Kask is sleek and secure, but not as customizable.
