Query: Comfortable, Stylish, Well Built

Having never been in a serious crash (knock on wood) I cannot comment on its effectiveness but the comfort and build quality are very good.I'm new to helmet wearing so its a little funky for me to have one on but you quickly forget about it once you're on the trail.The brim is removeable but I've never tried to take it on or off.The rear strap at the "Y" connection do in fact twist against your face and do not lay flat. This can be bothersome to a degree BUT the nylon is rather soft, and when the connection is set lower to around the jaw line, you arent really bothered by it.Ventialtion is pretty good, my head never feels hot. If you tilt your head down just a little bit on those boring sections, you feel the air work its way through the helmet and really cool you down.Overall I'm pleased with the helmet, I hope I never find out how effective it really is.
