Might want to look into dirt bike protective gear. I am personally a fan of Leatt but there are loads of brands to choose from. I have never ridden a horse wearing dirt bike gear but I have hit the ground and trees many, many, times while dirt biking and it has served me well.
A buddy of mine was talking to his doctor not long after he turned 50 and he was complaining about some random pain. The doctor told him “You know all that stupid stuff you did when you were younger? That’s what hurts now.”
