As a die-hard mountain bikers I've worn stuff on their heads. My last 12 year old Bell helmet with pumping system was a blast, but had time to be replaced. He had only 10 vents (sweat!), But was weighing 265g even then very easy. After I had tried everything from specialist dealers from Alpina via Giro to Uvex, I took the MET from the shelf. The fit just once - and that is not due to a lack of adjustment of the other helmets. This helmet has simply no noticeable pressure points thanks to 20 vents you really forget that you have it on. So I shot him myself here for 68 euros in brown low and am super happy. The matt, rubbery finish of the surface is also sometimes visually different. My absolute buy recommendation !!!
