Frameless packs will mold perfectly to your back but generally dont allow you to add any serious weight without putting a lot of stress on your shoulders and on the pack itself

If you're on a bit more of a budget then the Basic Tackle Box is well worth a look, as although it isn't quite as versatile with removable dividers and has traditional latches rather than magnetic fasteners, it is still a great tackle box

(Please note that the power bank is not included in this USB laptop backpack.) The headphone interface is easily accessible for easy earphone usage

Two will help keep the waggler and stops in place

I wouldnt go any bigger than that though
