Excellent helmet, sits low and conforms to your head, very stylish as well. The Kask Protone is a high quality helmet, very adjustable and fits very well on your head. It has a low profile and feels very snug yet comfortable while wearing. Lastly, it just look great while wearing... the best helmet I've owned. The price is well worth it, especially from Biketiresdirect.com
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. .
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.
Given the normal price - even the typical sale price - I had never even considered this helmet. From watching Team Sky and the GCN boys wearing it I really liked the look, but couldn't justify the money for something that probably wouldn't protect me any better than the $30-$40 helmets I normally used. Living close to the BTD store has some advantages besides saving on shipping, and I happened to come across a display model that didn't have the helmet case and was significantly cheaper than any sale price I had ever seen for these. I tried it on and the combination of fit, comfort, and aesthetics completely sold me. I have a slender head and face, so a lot of helmets look bulbous on me, but this one is quite sleek. Got compliments on the low-profile look from my riding buddies.
Have had this for a year now, and can honestly say it's one of the best bike-related purchases I've made. It might be subjective, but coming from a $40 commuter helmet I can notice an aero difference when I ride, and I especially notice the wind noise reduction. Not to mention it's a lot lighter than my other helmet. The adjustability is awesome, though it's tough to fit anything thicker than a lightweight skullcap underneath, so I do still use my cheaper helmet when it gets really cold. The strap is super comfortable and I don't get the skin irritation under my chin during the hot months that I would often get previously. We had a decent stretch of 90 degree days this summer, even a few in the triple-digits, and my head definitely stayed cooler than previous years with other helmets. Overall this is a winner for me!
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.
I was in the market to replace my Giro Synthe that I had to trash because of crash caused by a SUV cutting me off. I've always owned Giros but they never quite fit me right. I have a 59cm circumference head so according to Kask sizing, I should be wearing a large but the medium fits me great. I have a more round than oval shape head so that maybe the reason. Both the helmet and chinstrap are way more comfortable than my old Synthe. I love how the chinstrap lays perfectly flat against your face. That has to save a watt or two. ,-) I do have one minor quibble, my POC sunglasses do not fit that well in the air vents. Not a deal breaker but it's the reason I gave it 4 stars instead of 5.
Love this helmet! Light weight, vents extremely well, adjusts to fit a plethora of head shapes and it looks great. I love how bulk free the silhouette of this lid is - compared to say the POC or even the Giro Synthe, it almost disappears. It is a bit on the expensive side but give the quality of the materials used and the overall fit quality I would recommend this helmet to anyone.
I had been debating over getting this helmet for a while and finally pulled the trigger. I'm glad I did as all the positive reviews are valid. This is my secod Kask helmet and like the first, this one did not disappoint. It has a nice compact fit, good looks, and low weight. I've only ridden with this helmet so far in the warmer months and compared to a traditionally styledventilated helmet I seemed at first to be getting a bit hot under the hat. Then I figured out just to tilt my head up just a fraction higher and I would get a rush of air across my melon and I'd feel fresh as a daisy again. Whether it's an aero advantage or not who knows. I would buy it again just for its looks, weight, comfort and the high quality of Kask products.
This helmet looks great on my small-ish head. Most do not, so this one's a big win for vanity! More importantly, it always feels secure, comfortable, and doesn't move around on my noggin unless I want it to. I was surprised to find how good it is at cooling the noggin as well you wouldn't know it by looking at it, but ventilation is excellent. In fact, on my very first ride with it, ventilation was obviously improved over my previous normal helmet. Aero? I can't really speak to that. Maybe I'm the tiniest bit faster, but I bought this helmet for comfort, safety, and vanity. As advertised, the helmet is highly adjustable, and the leather chin strap is definitely a nice touch.
So why only 4 stars? Glasses. Neither pair of my sunglasses will fit securely and comfortably with the helmet. The arms seem to fight with the rear cradles. I'm not the only one to experience this problem. However, I've found that if I adjust the cradles just so, I'm able to wedge the arms through them - and that's the only way to prevent my glasses from slipping down my nose. This in turn makes a very comfortable helmet somewhat less so. So that's a bummer, but for me, the benefits of this helmet still outweigh that single (but significant) drawback.
The Protone feels light on my head, even on longish rides (3 hours), and is very easy to fine tune for the perfect fit. Chinstraps are fixed at the Y-juncture below the ears, so you don't have to dial that in to seat the helmet evenly on your head. Ventilation is great, I admittedly have not yet ridden with the Protone in temps above 75F, but with ample vents and air flow I expect it to perform well in summer heat. The Protone's profile is sleek, which presumably cuts down on aero drag (caveat I haven't seen any data to support this so take that feature with a large grain of salt). Materials and workmanship are impressive, as are small details like the leather chinstrap.
One drawback, which may or may not be significant the retention system takes a lot space around the back of your head, and can interfere with sunglass placement. I've tried the helmet with three different types of sunglasses (Oakley, Rudy, and Tifosi) and their temple ends all bump the Protone's retention hardware. Mildly annoying to me, but not a deal breaker.
I ordered a medium Protone and it fits perfectly by itself or with a thin cap. It does not fit, however, with my wool winter caps. Based on my other helmets, I'd say the Protone runs slightly smaller than Giro, POC, and Lazer. If your dome is in the 57-58cm range, you should size up to a large.
this helmet is worn/designed/tested by team sky. Finally available to the retailers in my size
Tried out over 115kms in coolmild conditions with climbs and descents and proved to be what it claims
The design is more rounded than traditional helmets and no mushroom look
The venting is very effective and the padding and fit system fantastic
It simplifies the adjustments to me.......very easily
Minimal noise when riding and of course picked it up for a steal
