I have two vests that I use, one for trout and one for salt. Plus I have a shoulder bag that's just for smallmouth fishing and 3 boat bags. One warm water, one salt, and one trout.
Some days I'm dressed up like a Orvis ad (Cabala's really
) and other times it's just a lanyard, a tippet spool, and a fly box.
Like all things fly fishing, "it depends"
