i have the giro combyn and i love it once you were it for a bit it like heat molds almost to your head so it has great fit also i have smacked my head on rails a bunch and it never broke it almost felt like falling onto hard memory foam i have also attempted a cork 7 with it on a 30 footer and my head was fine when i crashed i advise the helmet its great i love mine also don't get the discord it just more expensive has closable vents and a bigger rim
get the combyn it looks sick and is sick
