I use the gloves to drive in colder temperatures and rain to work with my 125cc scooter. The distance of 12.5 Kilimenter I have already repeatedly denied in the rain, temperatures of about 5 degrees and partly icy wind with the gloves. Even at low Temeraturen you get maybe cool, but never cold hands. Heavy rain they are loose away. You need just a long time to be dry again (up to 24 hours if they are not laying on the radiator).
For the price of just EUR 13, - you thus get a very good product.
As they are for long distances and in the summer I can not say. But I did not buy.
