Nice price Good fit Head can get a bit chilly from the holes in the helmet but that can be rectified by wearing a thin beanie hat Feel much safer wearing one than not now :)
Good helmet good price simples.
Overall this was a good product but it was too big for my wife. It is very difficult to size a person when not able to try on the product. No fault of Decathlaon.
Decent quality helmet for the price
Good cycling helmet, good value and good fit
Good value for a helmet that is for occasional use.
Bought one of these helmets at the start of the year and recently came off my bike on a downhill trail, quite concussed but the doctors are pretty sure this helmet saved my life. It may be a cheap helmet but it’s done it’s job.

European standard setting out the requirements and test methods for helmets to be worn by users of rollerblades, skateboards, scooters and bicycles.The corresponding requirements and test methods cover the following aspects: construction, including field of vision; shock absorption properties; characteristics of the retention system, including the chinstrap and tightening devices; marking and information.
We recommend replacing your helmet in 2 cases:1/ After a fallIn the event of a fall, the material of your helmet can deteriorate or even break. Sometimes, you won't even notice. That is why we recommend replacing it if you have the slightest doubt.2/ After 5 years of useThe foam of your helmet degrades over time. It can deteriorate due to impact, where it is stored, the climate, and its use. We recommend replacing your helmet at least every 5 years
Follow these 2 quick steps to adjust your helmet in 5 minutes:1/ Clip the 2 straps with the buckle: check that you can still slide 2 fingers between the strap and your chin.2/ Finally, adjust the tightness around your head.The helmet should be in contact with your head, without tipping forward, backward, or sideways, even when you're moving.
