Simple and effective helmet

Lightweight helmet, comfortable to wear and easy to clip on

XL model

It is very light yet sturdy and the price-quality ratio is good.

The size and width of the hat is not suitable for Asians. It is too narrow and very uncomfortable to wear for a long time. The top of the head cannot fit completely and the hat will shake when riding. I regret buying a poor product.

A little hard to put on the straps

A quick deal.

light and distribution of…

lightweight and balanced weight distribution (does not fall on the forehead like my old helmet)

I got a defective item, the paint came off and the service department quickly replaced the product

The helmet buckle is very short, very short, super short. It can only be buckled tightly when it is loosest.

Super safe helmet

Luckily I was wearing a helmet during my bad fall. Normally I am not a helmet fan, but thanks to the comfortable fit, light and good ventilation of this Decathlon helmet, I have been wearing it for several months now. The helmet did its job when I rolled over and hit my head against the road surface. This helmet has really saved me from more serious injuries.


Good quality.

Top bike helmet

Great lightweight helmet. Only problem: having to stick 1 “3M SELF-ADHESIVE SUPPORT FOR CLIP-ON LIGHTING” to install the light on the back of the helmet


The helmet is comfortable and light, sometimes you don't feel like you're wearing it. I usually wear size L, but in this case I had to choose XL, luckily I bought it in stationary stores and could try it on. People who buy online should take into account smaller sizes.

Great helmet

I ordered online and the last XL was just fine for my big head. Decahtlon handled this very flexibly, they replaced the first ordered L. Easy to adjust and very comfortable helmet. And of course it goes with my other Van Rysel stuff! :) I accept a decathlon promotion! :P

In-mold molding technology and eps

The In-Mold molding technology used in manufacturing this helmet makes it possible to mold the external polycarbonate shell during the expansible polystyrene (EPS) injection stage. This results in a structure that is much stiffer, very durable, and extremely light. The inner EPS structure absorbs the energy generated during an impact so that it is not transmitted to the skull, while the stiff external shell provides the helmet with longer-lasting durability.

Storage instructions

Keep away from UV rays (direct sunlight exposure) to avoid premature deterioration of the helmet.Do not expose to high temperatures (140°F max.); store in a dry place.
