I have this fishing backpack:

Which is fine for carrying to a spot and putting down and on a boat but seems to big to carry all the time while fishing.

When I have it fully loaded it has 5 plano boxes (and I could probably squeeze in a 6th), a spinnerbait box, fishing tool, scale, fish grippers, a ton of soft plastics, extra gaiters and gloves, a snack, water, and probably some stuff I'm forgetting right now.

 

In fact, the problem for me is that with all of that stuff it gets too heavy so I usually don't carry a full load.

 

One mod I am going to make is attach some velcro holders on the back so I can attach a lightweight, folding tripod stool.

As soon as an Amazon gift card I won arrives I'm ordering one.
