I know what you mean Don, the bulky clothing is a pain. I was out yesterday hunting and temp was 28 when I headed out, lotsa layering and the wool coat to top it off makes a puffy forearm. I put on a long leather arm guard and still have to adjust my shooting style to my more bent arm hunting style of shooting.
I've gotten used to shooting like this over the years so not a problem, still dislike all the bulk though.
