Product Customer Reviews

Rarely in stock but worth the wait. These liners great in both summer and winter.
Fits perfectly under the bike helmet and prevents bad sunburn of the scalp
Hi Jim,
Thank you for taking the time to write to us about your product experience.
Thanks & Regards,
Decathlon Brampton Team
It's a good hat, fits under a bike helmet and packs v small
Excellent quality and service
Worn throughout the year, cool enough for summer including trips to Spain and warm enough for most of the winter. Worn yesterday for a foggy 30 mile ride at 1.9° and still warm
Perfect. Keeps the Helmet fresh and new whilst protecting the hair.
I have male pattern baldness and sunblock on your head can run down into your eyes on a hot humid day. Also my helmet leaves lines on my head on long rides. I'm pleased to be able to say that this helmet liner is £4.99 well spent. I used it on a 3 day event in May with rain first thing becoming hot sun later and this helmet liner is very comfortable and protected my head from the sun without needing to apply sunblock. It works for me.
I bough two, one for cycling and one for my motorbike both in hot humid Thailand. For the motorbike helmet it helps soak up any sweat so i wash it every evening. It means i don't have to keep washing the helmet lining. For bicycle i haven't noticed any cooling effect (as described in marketing 3 degree reduction), jury is out on that. It does leave a mark on the forehead, hard to avoid.
There was no choice of size and my husband has a large head. It's therefore not a fashion accessory on his head but he has not got sunburnt where he is thinning on top which was the reason for the purchase.
Not quite the Decathlon competitveness on the price front, as when you shopped about better brands were available for cheaper on some sites. Love the cap though and have already used it for hot days to soak the sweat, and cool days instead of the buff to maintain some warmth under the venting.
The product is really good
I generally use it for my long rides and BRMs. Perfect fit and comfortable for long durations of helmet wearing.
Helps absorb sweat, dries fairly quickly.
Useful for cycling helmet gets study becouse of this
Good
