Having heard good things regards hjc helmets I took the plunge with the is17 lid in gloss black , along with a smoked visor for the summer . It has DD instead of those pesky seat belt type jobbies , always a winner in my book . What can I say regards fit and wind noise , well the padding lay out really suits my head and wind noise is minimum .Air vents are not super duper but you get a little and the ease of use of the vents is great . Vison and visor gets a huge thumbs up , great vision and the rachets on the sides make for a quick visor change , along with a reassuring feel on notch's when moving visor from closed to different stages on the way to being open . Add the above to what I consider to be a great looking helmet then its a winner !
