The only accurate opinion I can give is about fitting on head .
But the most important is the efficiency of the helmet if crash or fall occur , what of course I hope that t will not happen . I trust decathlon that test have been done for reducing dammages in such cases !!

A nice sturdy helmet, with easily adjustable head alignment mechanism at the back. Ideal colour for being visible on the road. Have used it many times now and is very comfortable and lightweight, just what you need from a helmet.

Just arrived in the post.If this helmet was 50grams lighter (its 300g in large), it would be used by all sportif riders. Brilliant helmet; shape is not too big, well vented. Because it's relatively slim, my rain cover fits perfectly onto it. Having a big head with a not overly big helmet means I don't look like an area 51 martian head. Despite looking trim, it fits well with the adjuster and there's enough room for a hood underneath (im size 58/59cm). Bright neon- I am definitely going to be seen.
Being a commuter-this is perfect. Being a velodrome enthusiast, I would also wear this helmet more so than my aero helmet because it fits so well. This is the best fitting helmet I have ever worn and I've tried a fair few road,pro end, and aero helmets (GIROS, UVEX LIGHT AS HELL HELMET, CASCO WARP SPRINT). It is comfortable also because of the pads, they are the most well cushioned I have seen on any helmet. This beats their cheaper helmets I have worn the last 2 years, and definitely beats the hell out of Giro helmets (weird sizing has meant I've had to wear extra large giro helmets with poor adjusters too). PLEASE MAKE A LIGHTER RACING VERSION, many racers would buy.
Everything!!!!
weight- being nit picky!
Saved my life
The best test of a helmet is to crash while wearing it. I did that, not on purpose of course, and the helmet did its job.
After hitting the deck in a 30+mph i whacked my head off the ground. My helmet broke taking the impact and i walked away with nothing but road rash.
I plan on buying another, it looks pretty good too! Thanks btwin!

The strap adjustment could be better. The under ear clasps move too easiy and the strap just won't stay tight, However for £27 its a decent enough lid.
Low cost and reasonably stylish
Strap seems to loosen every ride.
