Many big fish anglers, especially those on shorter sessions involving long walks or regular moves between swims, still prefer a back pack style tackle carriage solution to a larger carryall bag. Shimano have recognised this with the provision of 25 and 55 litre capacity Tribal Extreme Back Packs in the new 2009 range. Equipped with waterproof bases, generously padded twin shoulder straps, rigid zippered side pockets plus front pocket with clear fast access panel, all zips and straps are built to last.
