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.
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.
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.
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.
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 doesn't interfere with my sunglasses at all. My only issue is the price. I got it on sale but still it's very pricey hence the value rating. If you can afford it, get this helmet. It's a quantum leap forward from my old Giro Atmos helmet.
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.
