Kask Protone Icon.
Polycarbonate in-mold shell wraps around the back with Octo Fit micro-adjustment in both vertical and circumferential axes.
The Verdict.
Gavler Meta-Score
“The Protone Icon's Tour de France heritage is earned through thousands of professional race hours, not marketing. The Octo Fit system provides the most customizable fit available, and the wrap-around polycarbonate shell adds protection where competitors cut corners. It's the helmet that professionals choose when they can ride anything — and that endorsement speaks volumes.”
The Gavler Verdict
Precision Engineering
Octo Fit Retention
Two-axis micro-adjustment in vertical and circumferential planes for the most customizable fit available.
Wrap-Around Shell
Polycarbonate in-mold shell extends around the rear for reinforced protection where many competitors leave EPS exposed.
Italian Manufacture
Made in Chiusaforte, Italy with wind-tunnel-tested aerodynamics and meticulous quality control.
Technical Specifications
The Scoreboard
Professional pedigree, all-weather comfort, and the Octofit+ retention system are consistently praised. Kask uses its own WG11 rotational-impact testing rather than a MIPS liner; warm-running riders note the thick front pad can gather sweat on the hottest days.

Global Critique
“Still one of the most reliable helmets out there — the Octofit+ harness offers nearly infinite adjustability, anchoring the helmet with a neck stabiliser that cradles the lower skull.”
“A great fit and a comfortable option for all weathers; 20 vents and Coolmax padding keep airflow optimized, making it noticeably cooler than some premium rivals.”
“The same but better — Kask kept the Protone's pro-peloton silhouette and added WG11 rotational-impact testing in place of a traditional MIPS liner.”
