The development of backpacks is originally due to the need to carry luggage. How to carry weight for a long time and achieve a comfortable balance, the selection of backpacks is nothing more than liters, weight, material, function, and carrying system.
Size and purpose of capacity
The recommended capacity is 35-40L, which is the most suitable. It can almost meet most activities in the future, and it should not be less than 25L.
Why is this capacity the most suitable:
When going up the mountain in autumn, which is the most suitable for mountain climbing, the temperature in the city at night is about 15-11 degrees, and after going up the mountain, it is about 10 degrees lower, and the temperature is about 11-15 degrees. It will be directly spread in the sun. Generally, long-sleeved sweat-wicking clothes and an outer windproof jacket are enough during the journey. If you continue to walk, you will not feel cold. What you need to prepare in the backpack are warm clothes when you are still resting. (fleece, down jacket, fur hat), jackets (film clothing such as Gore-tex) when the weather is bad, drinking water, simple food.
A single-day trip can carry a lot of equipment less because the accommodation tent and food are omitted.
Water Bottle/Bag System
The water bag system is highly recommended for mountaineering trips. Water is replenished through straws during travel. Because of the mountain road conditions, and not all road sections are suitable for stopping to take a water bottle to drink water, and the placement is designed to be close to the back, the inner side of the backpack, for backpacks The center of gravity configuration is excellent, because water is indispensable and incompressible in luggage, and it is a one-to-one existence. Traditional kettles need to succumb to the convenience of containers and access, and their locations are in inappropriate places. Backpack packing tips, the heavier the thing, the closer to the back, the hydration system solves this problem (the only disadvantage is probably that it is not easy to know how much water is left).
If the water supply is insufficient in a low-temperature environment, the probability of dehydration leading to loss of temperature will increase a lot. Water is the most important substance for human health. Even without food, as long as they are hydrated, they can sustain life for many hours and improve their chances of being searched and rescued. For a one-day alpine trip, it is recommended to carry at least 1~1.5 liters of water, especially if there is no water supply in the middle.
Piggyback System
Mountaineering backpacks exist to carry things. One of the most important missions is to achieve comfortable carrying. Comfortable carrying is much more important than the weight of the backpack. The backpack is just like clothes. There are different sizes, if you wear it too small If the clothes are too small, there must be something wrong with your body, so the actual back test is very important. Professional stores will provide sandbags to simulate the load, and backpacks must be tested on the back.
There are often people looking for a backpack who only wants to take the lightest weight, such as a top bag. This type of backpack is only a few hundred grams. There are only two shoulder straps in the natural structure, and the back is also thin and foam. It is only suitable for short-distance carrying. Loading too much weight can be a burden on the body for long distances.
