Pockets are great and useful when being mobile, but they do have their downsides.
- The biggest issue we used to have were tools accidentally being taken home.
- Its one less place to look, when something is missing.
- Aluminum shavings have a way of ending up in the pockets.
I realize pockets are useful on home construction projects. But in the shop, I never use my pockets. Not even for a pen.
Everything stays on the table. I group the tools on one side, the robot and actively used parts on the other side and backup parts in a box. It makes it easy to find stuff when everything is visible.
For those in hot environments maybe something like a fisherman's or cameraman's mesh vest would work. Breathability and pockets in one garment.
