The most common misunderstanding of many newcomers about mountaineering backpacks is that they are equivalent to ordinary travel bags, and it is just right to "pack them inside" when packing - the result is either not enough or inconvenient to use.

When you are walking, you need to use the solar panel to charge, how can you balance it? When hiking, if you encounter a water source and want to remove the cup to draw water at any time, where should the cup be placed? These problems can be easily solved with the header Slotted Loop.
Hang solar panels, cups, etc. - There are four inconspicuous small Slotted Loops on the top of the head bag of many outdoor backpacks. Use quick hooks to fix the solar panels on these four small loops, and then carry the backpack, Shanyou. They can recharge while walking. In this way, the solar panel is firmly hung, the direct sunlight surface is large, and the body of the bag can be avoided as much as possible, which affects the holding of things.
When mountain friends are climbing, the water bag is usually put into the backpack, and the long water bag tube extends from the backpack and hangs on the chest, which is convenient for drinking water in time, but the dangling of the water bag tube is very annoying. The hydration tube on the upper shoulder strap is Slotted Loop.
Control the hydration tube - If you look closely above the shoulder straps of the pack, you will find a small device in the form of a webbing, plastic clip or plastic loop, here is the hydration tube Slotted Loop.
