I really do not know if they are allowed or not – But seriously, how much time is your butt going to be in contact with the seat during XC or stadium? Both rounds are just a few mins long at best, and XC is ridden in a half seat.
Perhaps you can warm up with it, then pull it off?
Thanks both of you for confirming that I'm reading this right ... New dressage saddle makes it a non-issue for that phase and I don't want to train one way and have to ride another, even if it's only half seat. (Note: this is only for schooling combined tests this year, anyway.)
