I like the Gappay vests but can't justify it. I already wear jackets with big side pockets (I'm always cold) and even then, I usually just have the ball in my left hand or in an armpit. I feel like if I bought one now, I'd have to re-train myself to actually use it. However, I really only use a ball for a reward so I don't need more than one hand, armpit, or pocket.
