James W.wrote a review of Kask Protone Helmet on June 19, 2019
Familiarity: I've used it once or twice and have initial impressions
Have been using Giro and Bell helmets forever, but wanted to try these lovely Italians. All OK but the sizing is weird and seems to be biased to narrow heads. The medium was always OK with me with Bell and Giro, but (after returning the Medium) I had to use the Large in KASK, which looks sort of funny on my head. Overall great looking and airy, but strange sizing and feel.
