Lucinda Fredericks of Australia had two items that I haven’t noticed on anyone else for Eventing dressage: a fleece/padded breastplate, and a full-cheek snaffle. I thought that very interesting. I guess the rules are pretty liberal when it comes to bits? And I’ve never seen a breastplate in dressage before, period.
The gentleman I just watched from the Netherlands was using a Boucher bit - first one of those I’ve noticed as well.
