In summer I use a fishing shirt. I can put a box in one pocket and camera and snack crackers in the other. tippet in the tippet pockets and hang gink and forceps off a pocket flap. Nippers and my Jeep key on a small lanyard tucked inside my shirt. I will attach an empty small filter water bottle to my belt if heading out from the Jeep for a longer distance. I really try to minimize or I spend too much time fiddlin' and not enough fishing.
In winter, I use the chest pockets on my waders and/or rain jacket.
