Anyone out there using back protection while riding? I took a spill on Wednesday and rammed my back into the nub of a branch that was cut off, it was mostly flush but had a bit of a point. Knocked the father, son and holy ghost out of me!! Put a hole in me too. I'm riding a Camelback LR these days (was using Camelback MULE for 25+ years) and I got hit just above the main pack. Maybe I'm just getting wussier in my advancing age but it gave me pause of "what could have happened"
