For those few who actually wear armor, do you have any trouble with the sode rotating behind the shoulders, leaving the shoulder exposed? I have thought of adding a cloth strap so that it holds to the arm. This is a replica suit of armor from Iron Mountain Armory so don't worry about me ruining an original antique set of armor! I will say that part of the problem may be that I have NOT been tieing the armor tight to my waist, and the shoulder straps are bearing all the weight. I have been using the yoroi obi on the exterior. I realize I need this on the inside of the do, with a sarashi obi on the outside. Maybe getting the shoulder straps off of my shoulder may help the problem, but I'm not sure this is THE fix.
Help is appreciated,
Dan
