Anyone have any recommendations on a loose fitting vest with rear pockets?

I have a Sugoi Monitor vest from years back that I still wear quite a bit. I haven't been able to find anything like it. It has a generous fit, but also is a reasonable length.

I'm not too big, around 150lbs 5'8". I've tried getting vests in one size larger so it's a bit looser, but then the length also extends which leaves things in my pockets down towards my buns.

Any recommendations?
