did it come with the 2 interchangable front ( chin area) parts?

The helmet is from the UK and cost me on an expensive side around 250.00.  I bought it's a great compromise on wearing nothing ang a full face helmet.  On local riding it felt light, airy and like wearing nothing at all. The field of view is execellent. It's as wide as the naked eye can see.  As far as noise, you can still the roar and whaling sound of the custom exhaust without the blistering his of wind noise. For riding without a helmet for awhile and just glasses alone,  maybe you guys, are all familiar  with the teary eyes- I'm not drunk feeling after a ride.  It's not issue with this helmet.  Sure, you get a tickeling  feeling from the wind around your nose and cheek, from where the visor ends, but you'll get use to it.  I cant wait to test it out on the express way and see how it performs on higher speed.  Will keep you guys posted.  So far, going 75mph, side to side movement of your head is not an issue.  No wind buffeting at that speed. I really like this helmet....to say the least.
