The first thing I noticed when I put this helmet on was how light it was and how it fit perfectly to my head. The chin strap is extremely comfortable. Out on the road I was struck by how quiet and how well ventilated the Protone really is - you totally forget you have it on. This is one extremely well engineered, aerodynamic helmet. It looks fantastic and doesnt interfere with my sunglasses at all. My only issue is the price. I got it on sale but still its very pricey hence the value rating. If you can afford it, get this helmet. Its a quantum leap forward from my old Giro Atmos helmet.
I race with this helmet, as do many others this season. Upon trying it, I immediately understood the Protone's popularity. It's very sleek (looks great from any angle) and lightweight, and the tightness adjustment system feels like it's cradling the lower back of your head - a reassuring factor as you're cornering at speed. Very happy with this helmet.
Best in comfort, style, and ventilation. This is my 7th helmet and I ride in Phoenix in the summer.
I recently received a Protone with a small crack. It could be from shipping damage, who knows. Today, I got my replacement, and it is perfect!!!! I am happy with the service. They shipped my replacement, before I even took my defective helmet to a UPS store. I will buy from you again. Thank you for great service!
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.
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.
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!
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.
