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.
