    Details

    Not just any lid will suffice.

    The Kask Protone uses In-Mold Construction. This means that the polycarbonate shell is bonded to an EPS foam body. This is then secured over a frame, which allows the shell to absorb impact while keeping the structural integrity of the helmet. The Protone is secured with Kask’s Octo Fit Cradle that adjusts to personalize the fit. The ECO chinstrap is antibacterial.

    Not merely a shell to keep your head intact, the Protone is also an essential aerodynamic accessory. The helmet’s interior padding is sewn from Coolmax, which helps to pull moisture from your head to keep you cool. To further assist with cooling, Kask placed the Protone in a wind tunnel and added large front vents and rear ports. The open design allows optimal airflow and doesn’t sacrifice aerodynamics.

    • Top your head with the helmet that tops Tour podiums
    • In-Mold shell increases structural integrity
    • Aerodynamically verified in ye olde wind tunnel
    • Adjustable cradle keeps your tactical muscle secure
    • Ventilation channels to encourage air flow and keep you dry
    • Anti-odor padding will fend off stink for way longer than 21 days

    Great aero at angles

    • Familiarity: I've used it several times

    Great fit after a little breakin (pads felt a little weird at first). At speed I was pleasantly surprised at this feeling dramatically more aero at angles than any other helmet I've used (Giro and Bell). In other words, you can turn your head left/right and not feel wind tug.

    I've used a number of helmets over the years, and so far this is my favorite by far.

    BIG

      Contrary to numerous reviews that I have seen and which I based my purchase, this helmet is not low profile, streamlined (sic), etc. I purchased large (59 cm) because I was at the very high end of medium. The helmet adjusted just fine but the size of the helmet made me feel as if I had a 2-3 gallon bucket on my head. I have Garneau and Giro helmets that I compared to the Protone . They are considerably more 'sleek' and have ample protection.

      Fantastic Cycling Helmet

      • Familiarity: I've used it once or twice and have initial impressions
      • Fit: True to size
      • Size Bought: Large

      I just received my Protone helmet and took it on a 60 mile madden voyage. I decided to transition from Laser Helmets to Kask based on reviews. I am totally glad that I made the jump. The Protone is by far the most comfortable fit I have ever had, and with all the different adjustments by far the most stable platform. I am glad I made this transition and totally recommend their helmets.

      Cool and Aero

      • Fit: True to size
      • Size Bought: Medium

      The Protone is a do it all helmet, it is both aero, and provides adequate cooling compared to some other "aero" only helmets. Wraps over, and around the head more than some other helmets, but don't even notice it is on during long days in the saddle, like it so much I have two now. The leather chin strap is a super high-end touch.

      Pretty excited about this helmet

      • Familiarity: I've used it several times
      • Fit: True to size
      • Size Bought: Large

      To those who felt that this helmet was heavy I feel that you are crazy. I can barely tell when I am wearing this helmet. I have worn this helmet up to 62 miles (100 km) without feeling neck pain from additional weight. The chin strap is very comfortable, as it is leather, but takes a little longer to adjust. The ONLY change I would make to this is to make the ear loops slightly longer. I just prefer them being a little more below my ears.
      The rear adjustment is great. I have worn it with my beanie on a cold ride and haven't had an issue. Even when riding unbuckled it sits well and doesn't slide around nor does it cause that headache from being too tight.

      I got the large and I wear a 7 5/8 hat if that helps any of you.

      So many PROs and no cons to the PROtone

      • Familiarity: I've used it several times
      • Fit: True to size

      I used this helmet on an Ingamba bike tour trip and I LOVE it! It is super lightweight and comfy it felt like I was not even wearing a helmet at all. Helmet has great sunglasses holes on the top too which are perfect for the all important pre-ride cafe stops and post ride pub stops. I wear a medium in all my other helmets and a medium in this helmet fit perfectly and accommodates a cap or headband underneath for colder rides. Here's a pic of me rocking the Black Protone with a cap under it. Seriously recommend this helmet.

      So many PROs and no cons to the PROtone

      Quality and adjustability

      • Familiarity: I've used it several times
      • Fit: True to size

      Coming from a mixino, which i really liked, i wanted to give the protone a try. Plenty of ways to adjust to your head's shape. The chin strap took a while to get used to, but now it's not noticeable. Ordered medium snd have 58 size oval head. Nice low profile and very comfortable.

      The Kask's subtle matte black finish doesn't try to compete with my Attaquer 'Bird Watching' kit... good thing cause the Attaquer wins every time. You simply won't find a better fitting helmet -- the rare bump that does sneak past my IsoSpeed decoupler is no match for the pre-dialed placement of my sexy Protone brain bucket. My only complaint, which is a small one, relates to the helmet's inability to house my Oakley Blade Trinity sunglasses when I'm rocking it sans shades.

      Road Ready!

      • Familiarity: I've put it through the wringer
      • Fit: True to size
      • Size Bought: Large

      This Kask Protone is the perfect road helmet. First, it is comfortable and the straps adjust to fit perfectly. Second, the venting works very well. No problem in the heat and humidity of So. Florida. Thirdly, The aerodynamics are amazing. Noticeably quiet and free of drag. I have no comment on protection, as I have not tested that feature. Easily the best road helmet I have ever owned.

      Best helmet ever!

      • Familiarity: I've used it several times
      • Fit: Runs small
      • Size Bought: medium

      I love this helmet! I have had a ton of different road helmets and this is by far my favorite. It is lightweight, has a classy leather strap, good color choices and overall looks super pro. I usually wear small helmets and this helmet starts at size medium, which fit me well so I think the sizing runs small. I would highly recommend this helmet for high performance road riding/ looking good at coffee shops.

      I need a small in this model. Kask does make it. Why does no one carry it? Plans to carry it in the future?

      Hello! Unfortunately I crashed recently and cracked my beloved Louis Garneau Course helmet so I am in the market for a replacement. I am interested in purchasing a Protone but have noted a very long possible wait for shipping. I do need a functioning helmet very soon and cannot wait 11 weeks. When will these be available? Thanks for your time!

      I've found a Kask Protone helmet at Cycles UK for $240.30 + free shipping. I usually buy my gear at CC and feel more comfortable buying through you guys. Would you consider a price match?

      Is the medium actually 230g, or is that just the weight of the European version? Sometimes the NA version is heavier with their different safely standards. Thx!
