I like a vest that hugs close to the body. The newer vests all seem to have great bulging pockets that protrude out from the body over an inch. That inhibits movement and taken to extreme can unbalance the vest itself and you too.
Think about the purpose of the vest. For me it is to hold objects and materials I will need securely and out of the way emphasis on out of the way. I'm one of those guys that hates things that poke protrude or in any way cause me to deviate from natural movement. l don't even like sandals that fit between your toes. Aaaccckkkk.
The number of pockets is irrelevant since you only need to fill the ones that fit your needs. My vest has like 24 pockets or something,. [I've never counted them] but I only use about six.
Think about the material the vest is made of. Ones that have netting around the shoulders or back will be cooler on hot days. Here in Colorado staying cool is not much of an issue for me, it's usually the opposite.
I like having the tab on the top middle of the back to attach a net to.
I don't think spending a hundred bucks or more on a vest is necessary either. l'm definitely a function above fashion guy. I'll spend the money saved on other fishing stuff that actually gets used.
Here's me in my cheap vest. LOL I didn't need a hundred dollar vest the catch this brown.
Bottom line. Laugh all you want. I got my vest from Wal Mart for $20 bucks. It's lasted a full season and has yet to fail in any way. It serves my purpose and that is after all what it is supposed to do.
