Super Light Weight
Bought it for snowmobiling. Super light weight and extremely vented for warmer spring days. Anything colder then -5c you might need an actual mx/snowmobile helmet.

Great Helmet
Amazing helmet, fits perfectly. It is light and looks absolutely amazing! Similar to a moto helmet, you can tell this is designed to save your head from big hits.

Like it so far
Fit is excellent, finish is good, love the weight of it for the size.
Haven't had the opportunity to use it as it is still winter here. So a 5 star rating could change

Instant Classic
I thought this would feel a bit heavy on my head like a MX helmet but no. Super lite. It is a very nice matt carbon black and I will be using clear sunglasses to avoid overheating in the summer which is a concern with these beauties.
