About materials
The materials of trekking poles are mainly iron, aluminum alloy, aviation carbon fiber, etc. Of course, there are more advanced materials, but the price is much higher.
Iron materials are not recommended, generally very heavy, followed by aluminum alloy, which is relatively cheap and has very good strength, comparable to carbon fiber, but the weight of aluminum alloy is often several hundred grams heavier than aviation carbon fiber. If you don't care about weight, then aluminum alloy is good. If you care about weight, then aviation carbon fiber is the best choice.
About handle type and material
Currently, young people use straight grip handles for trekking poles, and T-shaped handles are rarely popular among young people. About materials, there are foam, rubber, cork, EVA, etc. Although the cork handle is durable, Dong Ge doesn't like it very much, because it is very uncomfortable after the palm sweats. I am using the EVA handle now, which is not only non-slip, but also sweat-absorbent, and the use experience is also very good.
Cane holder
Cane holders are also called mud guards and snow guards. In fact, they are mainly used in mud and snow. The principle is to increase the ground contact area. At present, the cane holders of mid-to-high-end trekking poles on the market are all detachable.
So how to choose a trekking pole?
There are many factors in choosing a trekking pole, such as price, material, experience, evaluation, use environment, personal situation, etc.
