I certainly can’t remember any head injuries due to helmet failure back in the 80s
I’ve dealt with four in the last five years, all using crap Pro-Tec or Wildwater helmets, and more back beyond then. And a concussion to someone wearing a Rocker.
not even on “natural” rivers like the Trywerwyn, which I’ve navigated with my head nearest the river bed on occasion.
Likewise, and I holed a Pro-Tec flipping on Cafe Wave and swimming down to the raft egress. Fortunately the helmet took the brunt and I was dealt with a minor headache and a sore neck.
Having safety’d a bunch of slalom events, right up to Div 1/Prem, there were a lot of people in kit that I wouldn’t put a fresher into for a flatwater paddle, never mind for a slalom down Town Falls. While the cheaper plastic lids pass the BS/EN standard impact tests, I wouldn’t trust a helmet that I can flex the edges together without much effort…
Back on topic: Football, and the amount of money it attracts. Utterly does not compute.
