Re: [panavision] Back-Protection
I appologize if this is a duplicate post. The previous reply didn't seem to make it through.
My brother and I both jump with Dainese Shuttle Pro suits. A couple of months ago, he had a tailgate hang-up on a 165' span. He covered the distance to the ice in 5 seconds, roughly equivalent to jumping backward off a 15-foot platform. His tailbone and head took most of the force of impact. It looked bad, but he got up and did two more jumps that day. Without the armour, I'm sure he would have broken his back.
Dainese armour isn't cheap, but I think the quality is far superior to the cheaper Bohn armour.
The Shuttle Pro doesn't restrict your movement at all, and is very comfortable. In fact, I've done several jumps in a day without removing the armour just because it's that comfortable. With my old Bauer elbow/knee pads, I'd take them off right after I landed, because they weren't so comfortable.
If you're not looking for a full suit, I think the Safety Jacket mentioned by another poster is basically the top half of the Shuttle Pro.
The Shuttle Pro also has a sort of "cumberbund" that holds the lower part of the back plate in place. It also provides some abdominal pressure which I suspect stabilizes the low back.
