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.
The fit of the Protone is wonderfully adjustable and ventilated with an end result that makes it disappear.
Great helmet, been using it for several months now. Lightweight and comfortable, lots of vents throughout. I notice that the outer shell is very soft and brittle, well as least the matte version of this helmet, so be careful not to scratch or drop it. The front padding soaks up a lot of sweat when climbing in direct sunlight so I had to position the padding up towards the vents to help dry it out.
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.
Excellent adjustability and high quality chin strap.
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.
Very good aero helmet
This is the best fitting helmet with the best chin strap system Ive owned to date. The size is good and the outer shell size feels relatively small for a Large. The only criticism is the clear coating or sealant seems to be peeling in a few internal areas but not a big deal. Highly recommend
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.
Very adjustable, comfortable and well thoughtout. Best chin strap Ive ever had
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.
