I was watching the 2* at Nunney yesterday with a friend. I was absolutely horrified when a rider had a horse fall at the open corner and sat up with no hat on. I was about 30m from the fence and there is no way she had time to unbuckle her hat and sit up. I looked at my friend and asked if she had just seen what I had, and she confirmed that she had.
This rider’s hat had clearly come off from being too big. It was a very well known manufacturers skull helmet with heavy duty harness and there was no way that anything failed on that area as we later saw the rider put the hat back on.
After that I watched several riders going round cross country with hats that were too big. I cannot implore you enough to get your hat checked. It should not be loose on your head in any way and we know that hats are life savers.
It’s easy to be complacent about skull hats as I certainly only ride in mine for cross country preferring a show jumper style one for every day. But it’s a piece of safety equipment and in order to do its job it needs to fit.
