Kevin L.wrote a review of Kask Protone Helmet on June 23, 2018
Familiarity: I returned this product before using it
I am a multi-decade avid cyclist and a bit of a weight weenie. Been waiting for the Protone to show up in small ever since it came on the market. I ride in the Southeast hot and humid. Like the concept I could get a light helmet with decent ventilation and Aero properties to boot. Also loved the aesthetics matching my Dogma and kit nicely. Claimed weight on Kask site is 215gr and on CC site at 230gr in medium. Turns out when I received my small it weighed in on my Feedback scale at 278gr. I thought the scale must be broken. It also felt heavy when I put it on versus my current S-works helmet. Decided to return the Protone (love how easy CC makes this process) and buy the Giro Aeon. Aeon claimed weight is 211gr and came in on my scale at 213gr. I am usually skeptical of claimed weights but, Kask has taken it to a new level. Very disappointing.
