KaskProtone Helmet(Return to Product Page)

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.

I race with this helmet, as do many others this season. Upon trying it, I immediately understood the Protone's popularity. It's very sleek (looks great from any angle) and lightweight, and the tightness adjustment system feels like it's cradling the lower back of your head - a reassuring factor as you're cornering at speed. Very happy with this helmet.

Best in comfort, style, and ventilation. This is my 7th helmet and I ride in Phoenix in the summer.

I recently received a Protone with a small crack. It could be from shipping damage, who knows. Today, I got my replacement, and it is perfect!!!! I am happy with the service. They shipped my replacement, before I even took my defective helmet to a UPS store. I will buy from you again. Thank you for great service!

Protone kask helmet has a nice feel. Sizing is true to size and fits comfortably well compared to my old helmet. Nice upgrade and would definitely recommend it to my friends. Worth the bucks!

Great fit. The price is the lowest I can find comparing other website shipped from UK. The shipping is lightening fast.

If the helmet fits and the fit will not compromise your safety in a crash then it is a worthy investment. Of course, you would not know if the helmet is designed to protect your head until you crash and you do not want to do that to test it. My biggest complaint is I could not use it and returned it because if it is tight enough I would get a headache and if it is too lose it will not serve its purpose. The contour of the helmet is not compatible with my head and I could not get the right tension to keep me headache free and happy rider. The buckle and strap system is one of the best if not the best on the market as the leather strap will not irritate your skin and throat while riding, eating and drinking. Like all helmets and shoes, if the fit is not good do not use them even if you get your hands on a free one. It can be dangerous and quite uncomfortable in the long run!. Kask makes great helmets only if the fit is right! I have tried other models from Kask and unfortunately none fit me to warrant the investment. Some of them have too much plastic in the back I could not put on my Rudy Project (Rydon) glasses as the plastic in the back of the helmet was obstructing the ear pieces from sliding through and staying in place. .

Purchased this helmet for road use as well as some triathlon races.

Fit perfect and lightweight, really confortable during the rife and excellent quality.

Protone is used for road riding and mountain biking. I have used it with a liner for winter riding. Best feeling helmet I have owned. It replaced a Kask Mojito.

This is my new cooler weather helmet. Excellent aerodynamics with not a lot of wind noise around the ears, so it is easier to hear traffic. Looks good in matt black, already received several compliments. Easy to adjust.

Love this helmet! Light weight, vents extremely well, adjusts to fit a plethora of head shapes and it looks great. I love how bulk free the silhouette of this lid is - compared to say the POC or even the Giro Synthe, it almost disappears. It is a bit on the expensive side but give the quality of the materials used and the overall fit quality I would recommend this helmet to anyone.

Great helmet. I love the fit on these helmets. I've wrecked on two occasions, but the helmet did there job to protect my head.

Over the years i've used many top end helmets and this one seems to be the best.

This helmet is great for riding in the wind and listening to music on my Goal Zero bike stereo. Even with a stiff headwind, I'm able to keep the volume at a reasonable level. It seems a little heavier than the Gyro that it replaced, but is considerably more comfortable, so it's worth the very small sacrifice I'd say. This helmet also looks great, with a lower profile than most.

The warmest temperature I've used it in is 50F, so I'm looking forward to seeing how well it ventilates in the summer months. Previous reviews indicated that it's not an issue.

All-in-all, a great value.

Head size 22 and 56 cm approx. and purchased medium that fit well, strap and adjustment are very nice, helmet is light would definitely recommend.

Very comfortable and vents well. Doesnt look as mushroom as other helmets. Only downside is that Oakley glasses dont fit super behind the ears. They conflict with the fit system a bit.

Great fit. Easy adjustments with dial and tilt features. Interior foam and leather strap are comfy. Very light and aero. Cleans easily in shower.
