I have a super katana that is still not broken in yet that I bought early winter. Every time I train in it the shirt cuts into my right arm so badly that it bleeds (slightly). The left arm doesn't do this at all. Last Monday I benched in the shirt and have a long scab going from under my elbow all the way up to my shoulder on the under-side of my arm, down the middle of my tricep the shape and length of the stitching on the shirt. Since the left sleeve doesn't do this at all I'm wondering if something is defective about the shirt. Other than extreme pain when I'm near touching the shirt feels okay and isn't tight I don't think. I'm trying to stretch the sleeves out a big because my arms are too big for the shirt the way it came. I took a ball and inflated in the sleeves and left overnight. I will use the shirt again tonight so hoping it doesn't cut me as badly.
