I tend to wear my BP every time I ride these days and although you do get used to it, it does feel quite bulky and rigid to me. I wore an air jacket to ride my horse shortly after he was backed and unfortunately he was badly frightened by the noise when I had a fall and it inflated (he is a very anxious sort). When I rode the following day, he bolted in the school as soon as I was in the saddle, causing a second and worse fall!! It did set him back for quite a few weeks. I'm now quite reluctant to ride out with anyone who is wearing an air jacket as I'm not sure how he would react if they came off and he heard the sound of it inflating. All suggestions welcome as I loved my air jacket but the BP is at least quiet!
