Saved my life, Wear Alpinestar.
Bought helmet, did wheelie on surron, crashed broke bone, helmet saved me, buy helmet. In all seriousness this helmet is an amazing helmet that genuinely saved me although it broke my collarbone in the process it fit me well and it has virtually no helmet drag against the wind as opposed to my other helmets. I will be loyal to Alpinestar in the near future when I’m back up and able to ride.
