1. The specialized box call pocket. On my vest, it's on the 'wrong' side for my comfort since I'm a lefty. It's useless to me and too deep & narrow to be much use for anything else.

2. No clip for drinking end of the water bladder hose. There's one on the shoulder, but the end kinda stuck out and got in my way. As a result, I took the whole bladder & hose out.
