KaskProtone Icon Helmet(Return to Product Page)

It fits great and is so light I don't even know I have it on!

Love the leather strap and perfect fit

Fits great, ventilates, doesn't weigh much, looks good. I wear a 7 3/8 hat and this is a perfect fit.

3rd Protone I've owned and still my favorite. Great airflow, light and secure fit.

I use this helmet for road riding. I like that it is light weight, comfortable, and the ventilation is great.

I own 3 KASK Protone helmets. Having survived 2 serious crashes aboard 2 different road bikes, both without cranial damage of any kind, my black/red unit and my light blue unit are retired. I have owned many quality road specific helmets. It so happens that the KASK Protone fits my head as though custom formed for it. My first violent get off occurred when a medium sized German Shepherd darted out from my periphery directly in front of my wheel at 21 mph. 7 broken bones and a week in hospital. My helmet absorbed a major blow that easily would've been a severe concussion at best. That was the legacy of my black/red Protone. Severely scarred, but not fractured. Thank you KASK. More recently, i experienced a sudden deflation of front tire/latex tube, watching both peel off the carbon rim almost instantaneously. Freak happening. Lost control of the bike and down i went. Again, my noggin was saved by Light Blue that day. There might be equally effective helmets out there, but KASK has won my confidence with their amazing Protone.

This is my first Kask helmet and it fits my head much better than some other brands I've had. It's a little narrower in width than other brands so the sides fit me better without having to crank up the straps as much. I used their sizing guide and fell into the range that overlaps between the small and the medium so I opted for the medium initially since that's what I normally wear. After trying it on and seeing how much room I had prior to tightening the dial, I made the switch over to the small. It fits perfectly and has a little smaller shell than the medium so it looks better on me as well. The pads are comfortable and there are surprisingly few adjustments on the straps, but they're right where they need to be. I've seen others note that sweat management can be a problem with this helment and I can't totally disagree. It's well vented, but I wonder whether the pads are collecting sweat and then draining onto my glasses. I've only noticed it when it's in the upper 80's and humid though, so most days it's not an issue. If it weren't for that, it would easily be a 5-star rating. As it is, it's a really strong 4 1/2.

Protone(not icon). Both wheels slipped out today going around downhill decent at about 15-20mph. Complete wipeout and knocked out short period of time. Helmet toast. No brain damage. Get it!!!!

Fits nicely, glasses can store easily, adjustments are easy to do, good cushion feeling.

I've used Kask for years and it's the better option for me. Lightweight for hill section and fast on flat.

This helmet fits me perfectly. This is my second purchase as my first one really saved my head when a loose dog took me down. Great protection but a bit warm.

An absolutely great helmet. Fit was perfect. This is my 3rd Kask helmet. Other two are Utopia and Utopia Y.

I love the red color. Bought it for summer riding especially for the longer days with more climbing involved.

Liked it enough I bought another to gift to my best friend

My first purchase of a Protone was in the winter of 2021 when I knew my other Kask's three-year life expectancy was to expire that summer. I appreciated the easily adjustable, comfortable fit, breathability in hot weather and lightweight of both. This helmet's three years expire this coming July so I grabbed this Protone on sale this fall. Great helmet to protect the noggin!

This is the most comfortable helmet I have owned. Super light weight and feels safe. I would give this helmet 10 stars if I could.

Very comfortable, only one issue, the rear up and down adjustment moves too easily, not a deal breaker but a little annoying. Recommend it for serious road riding.
