Categories: Helmets

The Kask Protone helmet is a clever mix of aerodynamics and venting designed for the avid road cyclist. This helmet is most often compared in quality and utility to the Giro Synthe Helmet, often considered one of the highest quality helmets on the market, so the Protone has a high standard to match. 

The Protone Helmet is available for purchase in several different colors, so when purchasing, please make sure that you have clicked on the link for the correct color, because some vendors (like Bike24) only have one color available per link.

Satisfaction levels with the Protone tend to vary across the board, leaving many users happy with the efficient venting system, but others wishing that the helmet fit a bit more comfortably.  Doug McNamee at Cycling Hacks praises how light and well-ventilated the helmet is, saying that wearing the Protone was "almost like wearing nothing," something that might be especially beneficial on a hot and heavy ride. In spite of its light weight, most reviewers say that the helmet structure is highly durable and will keep your head safe from hard hits. While the Protone might feel light and airy for some people, still many others claim that the helmet is uncomfortable and difficult to adjust, creating a nuisance out of a piece of equipment that should be consistently comfortable. The Protone lacks adjustable chin straps, and fiddling with the adjustment mechanism during your ride could cause the helmet to shift out of place during your ride. Many of these critiques didn't seem to be entirely consistent from user to user, but those who had used both the Protone and the Synthe typically opted in favor of the Synthe due to concerns for comfort and cost.

The deal breaker for many reviewers who were skeptical of this item was the price of the Protone. But, since we're all about deals at Hammertime, we were able to find these helmets at a much more reasonable price point, making it easier to justify purchasing the Kask Protone. Though it might fall short of a couple of its competitors, this helmet is still a top of the line piece of equipment that will serve you well on many a ride.
