The modern angler needs functional and robust bags which are developed for special uses. So all the required equipment can be stored and transported easily. Bags which have a bottom made of rubber have the advantage of not getting wet. The bottom of some bags can be opened and so you can store there an additional box or cooling elements.
Pockets on the side are especially convenient for big bags and rucksacks. So you do not have to unpack the whole bag if you want something from the bottom. Parts which are seperated with a zip arrange the bag clearly.
Bags for particular purpose have the advantage that you can add special boxes to the bag. No matter if you fish for carp or catfish, the boxes and the bags are adjusted to each other and so all the neccessary accessories can be stored.
