I’ve “retired” 3 helmets in my time riding. The first was a pavement crash where I hit hard enough to crack the foam in 3 places (no doubt preventing a skull fracture). The second was my first full-face DH helmet, my head bounced-off several tree trunks while I tumbled through the trees. The most recent was when I highsided myself out of a turn (and over a small jump) in a bike park.
Yes, I’m a big fan of helmets. I’ll admit I don’t buy the most expensive helmets, I prefer to go with the more inexpensive MIPS helmets while keeping the price tag low enough to be (relatively) painlessly expendible.
