I like this Matte Black finish of the Protone! It is literally and figuratively so COOL. Because it is Matte Black, you can pair it with any color jersey and you will still look like you have a matching kit. The vents are really well designed that it cools my head during a hot Southern California mountain climb! Also the design is so Aero that it gives you that advantage, now I can also enjoy the minimal gains that this terrific product provides and I love it....I have TWO of these already and planning on getting a 3rd one!!!! That's how much I like the Protone helmet from KASK.
Great helmet, been using it for several months now. Lightweight and comfortable, lots of vents throughout. I notice that the outer shell is very soft and brittle, well as least the matte version of this helmet, so be careful not to scratch or drop it. The front padding soaks up a lot of sweat when climbing in direct sunlight so I had to position the padding up towards the vents to help dry it out.
The Protone is a great helmet for long rides. Recently used it while riding a century a few weeks ago in 80 degree weather. I have a black helmet and I never felt over heated because it's well ventilated. It's also super light and fairly aero.
This is the best fitting helmet with the best chin strap system Ive owned to date. The size is good and the outer shell size feels relatively small for a Large. The only criticism is the clear coating or sealant seems to be peeling in a few internal areas but not a big deal. Highly recommend
If the helmet fits and the fit will not compromise your safety in a crash then it is a worthy investment. Of course, you would not know if the helmet is designed to protect your head until you crash and you do not want to do that to test it. My biggest complaint is I could not use it and returned it because if it is tight enough I would get a headache and if it is too lose it will not serve its purpose. The contour of the helmet is not compatible with my head and I could not get the right tension to keep me headache free and happy rider. The buckle and strap system is one of the best if not the best on the market as the leather strap will not irritate your skin and throat while riding, eating and drinking. Like all helmets and shoes, if the fit is not good do not use them even if you get your hands on a free one. It can be dangerous and quite uncomfortable in the long run!. Kask makes great helmets only if the fit is right! I have tried other models from Kask and unfortunately none fit me to warrant the investment. Some of them have too much plastic in the back I could not put on my Rudy Project (Rydon) glasses as the plastic in the back of the helmet was obstructing the ear pieces from sliding through and staying in place. .
This is my new cooler weather helmet. Excellent aerodynamics with not a lot of wind noise around the ears, so it is easier to hear traffic. Looks good in matt black, already received several compliments. Easy to adjust.
Still in the early stages of using my new Kask Protone. Initially drawn to it by positive reviews from ride buddies. Compared to my previous helmets I can tell and feel that this is made with a view to cutting the air efficiently. It is comfortable with good venting and a high quality retention system, which on a ride lasting several hours on what could be a hot day, is critical. My previous helmet looked like a mushroom on my head - this does not. Plenty of flexibility in the retention to accommodate cold weather skull cap or liner. Sunglasses fit without problems. My only issue is that it feels a bit too snug on my forehead which I expect is more a function of my head shape rather than being any sort of design flaw.
I tried Giro first, but found the fit isn't for my head shape, the giro helmets are for rounder type heads, my head is thinner on the sides even though I wear xl helmets. The proton fits my head like a glove, even, and balanced. It's ducts keep my head nice and cool on hot days. During 50f days, it was too efficient, making my head cold, but I should have worn something underneath the helmet to cut the wind. I've had a ton of helmets over the last 30 years, and although it isn't the lightest, it fits the best!! Being aerodynamic, it reduces air drag in fast descents. I always catch my friends on descents, not sure what percentage is attributed to the helmet, but I'm sure it contributes in reducing drag.
