The Protone is the ''do it all'' aero helmet by KASK. The Protone offers the optimal combination of aerodynamics and cooling. Thanks to its Octofit adjustment system and divider ear straps you can adjust your Protone easily, quickly, and precisely for a perfect fit. Its eco-leather strap is very comfortable and prevents irritation to the skin. This strap is washable just like the helmet pads. Thanks to these features the Protone is the helmet perfect for both competitive professionals and
stylish touring riders.
Kask didn't just trust on Team Sky's input alone, so they spent a great amount of time on data research, position analysis (how does a rider move on the bike) and thermodynamic studies. For example: what is the best way to put away cycling glasses in the helmet without increasing drag.
Comfortable to wear and offers great level of protection
Shows dirt and marks

Great helmet with an unlikable strap.
The helmet itself is great, it fits your head very well and is dry adjustable. It has the best dial of any helmet I've used. The only downside is the leather strap. It's not supple enough for one and it's also way too long. I don't want to cut it to size as it kinda ruins resale if I decide to get rid. I've had to tap it our if the way or it just looks rubbish and flaps about taking away the aero advantage the helmet is purported to give. A little disappointing and the only thing that stopped me rating this a 10.
Fits your head rather than sits on it.
Great tightening dial mechanism
Horrible leather strap

Superbly stylish and comfortable helmet
This helmet is light, supremely comfortable, looks stylish and is even aero. The adjustment dial and cradle make it easy to get a secure and comfortable fit. It's hard to fault. Not a full 10, but only because of the price, which is a significant investment.
A little expensive
