One of the 34 popular items, "Usage Mizukumi Bakkan". Such a water-based backpack has been upgraded and is now available! Various useful functions have been added even more than the previous version II. The biggest feature is the clear material on the front. If you put in the fish you caught, you can see it swimming. It is easier to see the fish by not clearing the back. It is also easy to fold because it has diagonal lines on all sides. In addition, a rod stand is included. This rod stand is removable and does not get in the way when drawing water. And since we have received customer feedback that "the handle part where the rope is wound gets in the way", the function that can be hooked with a carabiner is also a plus. Because it is a water-pumping bag that is indispensable for fishing, easy-to-use devices are directly linked to the comfort of fishing. Please enjoy aging with the evolved water-pumping backpack.
