I had a pretty rough crash about 3 months ago, luckily I came away with just a tiny fracture in my wrist, but I did hit my head while wearing this helmet and I know it saved [me] from a concussion or worse. Bought the exact same one again! Great helmet and it’s easy to adjust for the perfect fit! It’s also ventilated very well so that’s great in the summer heat!
