I also use a vest more than my chest pack. I just like to carry to much stuff with me. It always seems like I left something behind when I use the chest pack.
I just don’t feel right unless my back and neck ache after about ten minutes with my vest on. That thing must weight 20lbs its mainly filled with snacks, cigars, drinks, matches , extra matches, back up cigar, more drinks and snacks. Sometimes I put some fishing stuff in it. 😀
