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

Lightweight and comfortable helmet

Ideal for regular road cycling and for my outings

Unbeatable value for money

In terms of price and quality you won't find better anywhere else.

The helmet's belt buckle is a little difficult to untie, but it's really light.

Van Rysel helmet

Very good helmet, I was going for the road helmet at 65e but I chose this one anyway. Well super happy. Light helmet and excellent ventilation (no sweat on my hair after 53km and I have medium-length hair).

I'm feeling very good with the helmet. It is comfortable and covers your head well. Once tightened it fits me like a glove.

We have designed the helmet's inner ventilation to maximize thermal regulation of the head using the ”jet” effect generated by air inflows through the grille, 16 inner channels, and extractor.

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.
