i bought one from ebay. It was leather seat and flaps but had synthetic girth straps. It wasnt the best quality leather but it felt comfy to sit in though i never actually rode in it as it didnt fit my horse so sold it on to my friend. I didnt want to get another one as quality wasnt that good
However she said its really comfy
I had a synthetic one as a short term measure while my youngster grew up and it was actually very comfy. There was little 'finesse' about it, but it stood up well to hard work (and a far bit of neglect
I was thinking about ordering a gallop saddlle from north cove equstrian but cant quite decide between the rhinegolg synthetic dressage saddle or the gallop dressage saddle
