Best helmet

I've cycled for 30+ years and this is the best helmet I've ever worn. So light and comfortable I had to keep checking I was wearing it !

Van Rysel ⛑ helmet

Helmet is very light and apart from the fixed length strap irritating my left ear it is very comfortable to wear.

R900 helmet

Really nice helmet but sizes super small. Measured head and went medium but, at 57cm needed large. Not a criticism of the helmet just the size.

Bang for buck, under rated.

Excellent road hat for an excellent price, adjustment at the back very similar to Lazer mips hats and works well though I'd prefer some "click" feel. Weight also brilliant for the price, doesn't come with a huge box and loads of unnecessary plastic baggies and manuals like most hats do, so kudos for being responsible. As far as comfort goes I literally forget it's there - so that's 11/10. The only thing it's missing to make a really nice touch is adjustable straps around the ears (as they are glued to the plastic guide) but other than that the fit is perfect, it vents well and as a basic upgrade the aero difference is noticeable when you're up to speed.

Excellent Value

This has got great venting, looks aero and more expensive than it is. Padding is comfortable. Only one very slight niggle, the strap can be difficult to adjust properly, but not impossible. The size came up a little small for me so I would double check sizing before ordering. Overall I would highly recommend this helmet. Great work Decathlon! Cheers.


I find these really comfortable.

Van Rysel Road Cycling Helmet

This helmet did its job when I came off my bike and my head slammed into the kerb. There was a significant dent in the helmet, but I was unharmed apart from a few aches and pains for a few days afterwards. Replaced the helmet with the same one as I know I can trust it - but I don't recommend testing it like I did!!

Additional Product Information


Main lining: 100.0% Polystyrene - Expanded ; Shell: 100.0% Polycarbonate ; Buckles: 100.0% Polyoxymethylene ; Foam: 100.0% Polyurethane ; Webbing: 100.0% Polyamide

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.
