KaskProtone Helmet(Return to Product Page)

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 use this product for every bike ride, short or long. It's stylish, comfortable and different than all others. I have received many compliments.

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.

This helmet is light and good looking. Kask makes quality, light and fancy cycling helmets.

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.

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

Most comfortable helmet I have ever worn. Great price too. Kask Protone is now my Go TO helmet.

Very happy with my purchase. Great product from the people at Kask. Fits true to size. Comfortable. Vibrant colours. Helmet shipped extremely fast too.

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.

Nicely made, but the large size maxed out at 62mm. In this helmet I need at least a 63mm! So had to return it!

Out of my 6 top brand helmets this is my favorite. Great fit, better straps than other helmets, plenty of air flow in the Texas heat.

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.

This helmet is the lightest and most comfortable Ive ever owned. Dont look any further. Just do yourself a favor and buy it from Bikestiresdirect. You wont regret it.

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)

Nice dual adjustable head strap, gives nice, snug fit on head.

My favorite fitting helmet, looks better than most in my opinion as well.
