KaskProtone Helmet(Return to Product Page)

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.

Excellent adjustability and high quality chin strap.

Very good aero helmet

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

Very adjustable, comfortable and well thoughtout. Best chin strap Ive ever had

Helmet fit is good, not without its issues though. Padding does a good job but when it's hot out the padding fails miserably in keeping sweat out of your eyes. Also, the pads that are stuck onto the OctoFit system are horrible, almost as though KASK designed them to fail, fall off, and lose. For a $xxx helmet this is an utter design flaw. Pads should not fall off, and when they do (they will almost immediately) a slew of extra pads should be included with every new helmet. As it is you'll need to contact KASK and hope they have spare pad sets to send you.

Fix this or bring down your price, because $xxx is too much as the helmet is.

I like it overall. The combination padding and ventilation made this a very comfortable helmet. In the heat of the San Fernando Vally summer, the Protone is noticeably cooler that my previous Oakley Aro5. The sizing is little on the small side. My head measures 57cm and the medium just fits with very little room to spare. Which is fine because the most that I wear on my head is a thin head sweat cap. Also the padding will likely compress down over time. The straps are the best I've experienced on any helmet which shows Kask's attention to detail. The helmet seems to have a lower profile and doesn't bulge out like the Oakley and Giro's. I used my accumulated points which reduced the price by about 40%. As much as I like it, I don't think I would have paid the full retail price of $xxx.

I bought my first Kask helmet (a Mojito) three years ago at an end of cycling season sale from a shop in Colorado's Rockies. Having finally abandoned my leather helmet for fuller helmer protection in the early 1980's, I have owned scores of plastic-based helmets since then. But I would rate the Kask Mojito to be the most easily adjustable, comfortable, light weight helmet I had ever owned....until I purchased the Kask Protone. It is nothing short of amazing that the Protone is actually lighter than the Mojito, offers the same easily adjustable features and comfort, and provides even greater protection of the noggin than does the Mojito. Yes, this is a lot to pay for a helmet. But when I consider what an hour in an ER with a brain injury might cost, this is a minimal investment. That's why I also bought a Protone for my infrequently riding spouse. I want her to have the same level of protection as I have.

I already have a big head and my vanity will not allow me to slap a double-wide MIPS helmet on top of that. So after returning a top-o-the-line Giro that was as wide as my shoulders, I went looking for the lowest profile helmet I could find and Kask was the answer. Not only does is look great but you barely notice it. I just did a century last Saturday and I didn't think about my helmet once, even though everything else hurts. If it's not an issue over 100 miles it will never be an issue.

I have the Kask Mojito from a few years back. A really good helmet. It has a two way fit. The Protone has the Octofit. Its pretty slick how you can really dial in your fit. I bought a medium and and Im the upper end of the medium. I didnt need to adjust the chin strap. Im a big fan of how the buckle is offset and not in the middle of your chin. I gave it a few cranks on the back. Very nice fit. I cant say if this helmet is noisy as of yet, its gust in here today. Ive been more focused on staying upright. But my initial indications say its probably no noisier than any other aero helmet Ive used.

I have a large head and have owned a lot of helmets over the years, mainly Bell and Giro. This is the best-fitting helmet I've owned (I got the 59-62). I put it on and forget it's there. The strap connection points are adjustable so they position around your ears well, and the under-chin strap is comfortable. The buckle's in an odd place, right against the corner of my jaw, but I don't notice it while riding-mainly an aesthetic issue. The helmet nicely snugs around the crown and back of my head, and it's contoured well so it doesn't look too much like a mushroom atop my big head.

I may be imagining it, but the helmet also feels very aero from all angles. I ride in a lot of cross- and head-wind, and the wind doesn't seem to catch my head like it did with my Bell Sweep. I haven't ridden in hot weather yet so I can't speak to cooling or sweat management.

The Protone fits well, is comfortable and the slimmer profile makes it more attractive than many bulbous helmets on the market. The quality of finish is excellent and the level of comfort is high. A helmet is definitely worth spending extra money on if you find it comfortable, you like the looks and it provides some level of protection. As one who struggles with sweat in the eyes, the Protone offers little help. That said, I have yet to find a helmets solves that problem. Hats and headbands are my only solution. As usual, Bike Tire direct service was excellent.

Bought a Medium on sale and my 58 head fit perfectly. Adjustments are more advanced than other helmets on the market. Great chin strap. Bonus, I do not look like a mushroom.

i wanted to love it

It's not as comfortable as my POC Octal, the leather strap feels heavy and hot. It's smaller than my octal on the outside I like that. I guess I'm still looking for a new helmet. It does look nice, and the padding on the forehead seems to keep the sweat out of my eyes. It may grow on me.

The Fit of this Helmet for me is 5 Stars.. Plus the Strap of the helmet LIES FLAT on the side of your face down to your chin.... I gave a 5 Stars on the Value, it's because It's Worth it, as they say You get what you pay for, and most of the time that's true..... I always stare at the helmet even when I'm in front of the computer, it's always beside me since I bought.. ; ) it's funny I know but true.....

The Kask Protone is my favorite helmet not only for its looks but for the great comfortable fit that I get. The leather strap is comfortable and stays in place. I've cash tested two of these helmets and have walked away with no head injuries. Great helmets.

Lightweight, very adjustable, great airflow on hot summer rides. So comfortable that I forget that I have a helmet on sometimes. I have owned a bunch of helmets but none more comfortable than the Protone.

I have an enormous skull and this is a great fit, which is a rare treat. Cool and quiet. Love!

The Kask Protone is my favorite helmet not only for its looks but for the great comfortable fit that I get. It's lightweight and doesn't ride down on my sunglasses like some other helmets. I also like the assortment of colors available. Thankfully, I haven't tested its crash-worthiness but if the pro teams trust it, I will too. The only drawback is that it's priced higher than many other helmets.

The padding and leather chin strap make for a comfortable fit that's better than my previous Giro. Ventilation is decent for an aero helmet but I still get more sweat dripping into my eyes/glasses than I did with my Giro. All in all a good helmet
