Awesome Product lite weight Protects my Son's Head Well.
One of the best helmets I’ve owned. Do recommend-m-2018 KTM 250 XC-W (E-Start)--
The SM10 is such a great helmet. So many features packed into it. Super light and really well vented. I wear a medium is all helmets and still a medium here but I needed to get the thicker cheek pads that Alpinestars offers to tighten up the cheeks for myself personally.
Great fitting helmet, felt tight at first but feels snug on my head and just right. Definitely one of the best on the market
I liked the weight of the helmet, I don't like that it is made in China
