Well, after an eventful lesson yesterday (a lady who joins us every other week was thrown from the horse she was riding), I'm thinking a body protector may be a sensible investment.
I've had a little look around and the Airowear Outlyne seems pretty good, especially for people with a significant difference between chest/waist measurements, but to be honest they all feel really heavy and stiff. I haven't tried one on yet, so are they actually more comfortable when they've been worn for a bit?
I've always ridden without one, so have no idea what they're like, but yesterday's events were pretty unsettling - especially as I've ridden that particular horse previously and was going to have him yesterday. He's a bit of a grump, but everyone was shocked by the rearing and bucking - totally unexpected.
