This item can be attached to a sweat and rucksack to prevent your back from getting stuffy. Carry your daypack comfortably.
Have you ever had a rucksack on your back when you are climbing, hiking, walking or biking cycling? When you wear the "Sweat and Ru Kun" on the knapsack you can create a gap between your back and the daypack for better ventilation. When sweat evaporates, it steals vaporization heat and lowers body temperature for a pleasant experience. Easy to dry even if you sweat.

Lightweight and slim, so you can wear it without worrying about it.

■ Instruction manual 【For comfortable use】
How to attach to the di-pack: Press the stopper convex part of the rope on the top of the main unit with your finger, and pull out the two ropes. Loosen the rope through both the shoulder strap and the top handle. Press the convex of the stopper again to tighten the two ropes. Connect 3 other ropes to the Zack belt as well.
·If there is any discomfort in contact with your back depending on your body shape and shape of the zipper, you can adjust it by pressing down the stopper, extending the rope and lowering the "body" by about 2.0 inches (5 cm). It may be better to tie the rope loosely than firmly fixed.
