The one thing that should be considered in going down the vest path of kit building is whether or not the vest will become invisible.

I think that some multi-pocket models just do not fit the look needed to blend into the workplace. My wool vest in the Pacific NW works great in a casual workplace. I have worn this one or a nearly identical one since the first day I started my job here. If I take it off people ask about it....no one asks about it otherwise. So my tools are both contained and covered and secure in my "uniform". Starting to wear a solidly stuffed vest...expecially every day will cause comments, so it is best to look for one that will blend best into whatever work environment you have. This may be a silk vest, Filson vest, camo vest, photo vest whatever, but blending is needed and time to make this concept work.

It is almost like looking for the ultimate tin.....just a cloth one.
