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.
Had to replace my old helmet. Looked for a new one for a couple of weeks until I found one I felt was the best out there. Wanted light weight, keep your head cool, good fit and does not sit high on top your head. The Kask Protone does it all ! What made my final push to buy was the online chat help I received from the Bike Tires Direct representative. When I received it, it was better than expected.
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.
Overall I like the KASK helmet, reasonable weight, very well vented, but be careful on the sizing. I am a very medium sized guy but the medium helmet was almost too small on me. I had to max out the sizing adjustment ring to get an acceptable fit. Straps are well located, attachment buckle is on the side where it does not touch your head, so that is a very nice feature.
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.
Love this helmet.
I've always been fearful of buying helmets online as there is generally a round or oval config for the shape...Kask's design is amazing. No issue and a dialed-in fit every time.
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.
I love the fit. Very adjustable. The leather chin strap is very nice. I have taken a hard wreck in one and got my clocked cleaned pretty good but no concussion. Great helmet.
This is my second Protone one I bought Large which was too Large. This time bought medium it fits snug with enough room for caps. Very light and comportable. Havent test safety(I hope Ill never have to)
