Kask Protone Icon review: The pro bike helmet now better than ever

The Kask Protone bike helmet has had a facelift and is now better than ever. Comfort and safety are two key things to consider if you’re on the hunt for new headwear and, as our best guide to bike helmets reveals, the choices are many and varied. However, now that Kask has updated its hugely popular Protone model, you may not need to look at anything else.

Even the box it comes in suggests you’re in for a treat. Open said box and your hopes won’t be disappointed either. If you are already familiar with the Kask brand, you will know what to expect. If not, think about the premium, then double it. Of course, if you go for a high-end helmet, you’ll pay for that too, with the Protone being one of the most expensive pieces of safety kit you’ll buy. I’m ok with that though, as it’s a real quality item.

Kask Protone cycling helmet: price and availability

The Kask Protone cycling helmet is available now and it’s a top model, which means you’d expect to pay around £245 in the UK, $299.95 in the US and 409 AU$ below. That makes it an expensive purchase, but what’s the cost of personal security, huh? You can get a whole host of Kask bike helmets from Amazon as well as other cycle specialists.

Kask Protone bicycle helmet: design, manufacture and safety

If you’ve been following the bike for any length of time, you’ll know how revered the Kask brand is, with the previous incarnation of the Protone appearing on the heads of many Tour de France riders, Giro d’Italia entrants and riders alike. Strange Vuelta has Espana races too. Kask’s Protone was also part of the winning teams of competitors at the Rio Olympics in 2016, as well as Tokyo more recently in 2020.

What this means for us everyday riders who want quality safety gear is that it has been improved over time. Kask tweaked and refined the Protone, taking into account observations and day-to-day issues that surfaced during extended use by competitive cycling teams. The Octafit+ retention system, for example, is now better than ever. It uses a revised cradle, improved rubber inserts and a refreshed stabilizer that sits much better on the neck.

While there are a lot of things that will look the same if you compare it to the outgoing Kask Protone model, this is actually a new headset. Indeed, put it on your head and you will immediately feel the difference, compared to the old iteration. The improved internal frame structure feels much better in terms of ventilation. Competitive riders, who I suspect are most likely to buy this, will also notice the improved aerodynamics offered by the sleeker form factor.

It’s hard to find a lot of concrete information on the safety credentials of the Kask Protone bike helmet. However, I’m pretty sure that this brand’s pedigree and the fact that many cycling professionals use their products should ensure that this latest cover meets all the latest health and safety regulations. Despite the lack of MIPS (or Multi-Directional Impact Protection) as part of the design, Kask ensures its own testing called WG11 is more in line with real-world use. It’s good enough for me.

Kask Protone Bike Helmet: In Use

I’ve only spent a few days using the Kask Protone bike helmet so far and I can see why it’s such a popular choice for so many riders, especially professionals who don’t have to worry so much about the cost factor. The medium model I wear fits heads 52-58cm and is finished in a cool white color. However, you can choose one according to your taste as Kask offers a range of ten different color variants.

Along with the brilliant fit and finish of the Kask Protone bike helmet, it also feels great on my head. It weighs only 230 grams, so you’ll hardly notice when you’re wearing it. If you’re on your bike often and for long periods of time, it makes a huge difference. Likewise, the design allows for good airflow, which is also a godsend if you’re out in the hot weather and sweating on those endless climbs.

Kask Protone cycling helmet: verdict

It really is one of the best high-end bike helmets you can buy, both safe and stylish to wear. Kask offers the Protone in less than ten different colors, with gloss and matte finishes to choose from. It fits heads from 50cm to 62cm and is lightweight yet strong.

In fact, considering the high price tag, this is a bike helmet that should give you a few years of peak service. And, when you’re done, the Kask Protone will still look great hanging on your wall at home. It’s a very cool thing to watch.
