Kask Protone Icon
The comfort-first Italian classic — a balanced aero-and-vented shell with a plush, leather-trimmed fit
Key characteristics
Highlights
- ✓ Balanced design between aero and ventilation
- ✓ Plush pads with a faux-leather chin strap
- ✓ WG11 rotational-impact tested (no MIPS liner)
- ✓ Refined Octo Fit retention system
Our take
The Protone Icon is the pro-peloton favourite for a reason: it strikes a fine balance between aero and cooling, and the leather-trimmed strap and plush pads make it one of the most comfortable helmets you can buy. It uses Kask's own WG11 test rather than a MIPS liner, which some riders prefer and some don't — but on comfort and finish it's a standout.
