Two Major Features! There are two major features for anglers. One is that the length can be changed in two stages. The other is that it can be carried straight on your back with both shoulders. Length changes! It is designed to change the length using a retractable extension inner bag. Lengths from 100 to 130cm, and from 140 to 180cm. With two-stage lengths and multiple color variations, you can store fishing rods. Especially recommended for those who have several types of rods, those who want to "run and gun," and those who want to attack multiple points! Carry straight on your back with both shoulders! We have designed a special PU synthetic leather shoulder strap to enable easy point-to-point movement and carrying on both shoulders. With both hands free, you might be able to go to that breakwater or rocky shore point that you couldn't go to before!? Easy and safe for motorcycle or bicycle travel because it doesn't stick out to the sides! You can store 2-4 reels of size 4000 with the reels attached to the rods. The rod for the reel can store rods up to 34cm from the bottom of the rod to the reel seat (reel mounting part). Attention to detail! The main body is filled with cushioning material to protect the rods! Furthermore, there is one Velcro fastener in the front and two on the reel side, so you can store fishing rods of different sizes smartly. Reel storage, pockets too! Weight 530g and 630g. Rinse, dry, and fold for storage at home!
