Other than multidensity foam back pads in both my jackets.... nothing.
Been thinking about it, but haven't pulled the trigger.
The thought of being paraplegic after an accident is not a pretty one. I can't think of a single hobby I have cultivated that I could continue to pursue in that condition. Maybe have to take up stamp collecting
Always. I've got a 4-panel back protector for my Vanson and one for my Aerostich jacket. The one for my Vanson is pretty big and makes it less comfortable to wear off the bike. On the other hand, I got used to it pretty fast and now when riding I feel positively naked without it.
Your call, but in my opinion there aren't big downsides to back protection and there are huge upsides.
Most of my jackets some type of back protector, but I think I'm going to purchase a Bohn w/ in the next few days. You probably won't realize what its actually worth until you actually put one into use (hopefully you'll never find out), but you'll be and feel safer just by having one. check out
i got the dainese hard pack, which has a built in removeable back protector. the pack is pretty well made, just small. i take the protector off and use it by itself for longer rides when not commuting.
I just got some one piece leathers with a hard spine protector and speed hump that will actually help keep your head from whipping back and forth (It also looks kinda cool). When I commute I have a hard armoured jacket with about 3/4" of dense foam in the back.
If you do serious fast riding I really think full leathers are the way to go. Some people have a hard time getting over the price but that wont matter after a bad fall.
