There are many types of outdoor sports backpacks, and the commonly used ones are mountaineering bags, travel bags, bicycle bags, backpacks, etc. How can we make the right choice for a backpack with so many varieties and features?

1. Choose according to the type of outdoor sports backpack: travel bag. A large travel bag is similar to a hiking bag but has a different shape.

The front of the duffle bag can be opened with a zipper, making it easy to access your belongings. Unlike a hiking bag, items are usually placed in the bag from the top cover of the bag. There are many types of small travel bags.

You have to choose a comfortable back and not just focus on the looks.

2. It can be divided into hanging bag type and backpack type. The bag can be carried on the back of the bike or hung on the front or rear rack of the bike. The backpack type is mainly used for bicycle trips that require high-speed riding.

The bike bag is equipped with reflective strips that reflect light and ensure safety when riding at night. The bag consists of a bag body and an external aluminum alloy frame. It is used to carry bulky items that are difficult to fit in a backpack, such as camera cases, fuel tanks, etc.

In addition, many backpacks will often have a sign indicating which sports are suitable for.

3. There are two kinds of hiking bags: one is a large backpack with a volume of 50-80 liters; The other is a small backpack with a volume of 20-35 liters, also known as an "assault bag". Large mountaineering bags are mainly used to transport mountaineering materials during mountaineering, while small mountaineering bags are generally used for high-altitude climbing or peak assault.

Mountaineering backpacks are designed to cope with extreme environments. It is beautifully crafted and unique. In general, the pouch body is thin and long.

The back of the bag is designed according to the natural curve of the human body, so that the body of the bag is close to the back of the human body to reduce the pressure of the shoulder strap on the shoulder. The bags are waterproof and won't leak even in heavy rain. In addition, mountaineering kits are not only used for mountaineering, but are also widely used for other adventure sports (such as rafting, crossing deserts, etc.) and long-distance travel.

4. Choose according to the function of the outdoor backpack: durable, walking on hiking trails, or climbing on rugged rocky ground? Different route environments require different equipment, and the abrasion resistance and durability of the fabric should be considered.

In general, the more durable the fabric, the heavier it will be (or choose a strong, lightweight fabric like X-Pac or Dyneema, but at a higher cost). So, weigh in whether you want to prioritize durability or get rid of those extra weight burdens. Waterproof and non-a** weather, everyone wants to hike in clear weather, but sometimes there are bad weather such as rain and snow.

5. It is necessary to carry a backpack with good waterproof performance. When choosing, pay attention to whether the fabric is highly waterproof, or whether it is equipped with a rain cover and corresponding design features such as roll mouths, waterproof zippers, etc. Obviously, the right post-packaging requires the best equipment.

Excessive capacity adds unnecessary weight and volume. Exterior elastic side pockets, kangaroo cases, and hanging points make it easy to store large items such as coats, water bottles, and quick pick-up items. Make full use of the backpack's outer dividers and suspension points.

The backpack you choose should be looser, and it won't be particularly stiff when hung on the body, and the backpack should have a large capacity, so that you will find it easy to carry such a backpack on your back in outdoor sports.

To choose a waterproof type of backpack, the schoolbag should be equipped with a rain cover, the durability and wear resistance of the fabric should be considered, in order to be in case there must be too many things, so you should buy a large-capacity backpack, you should buy a backpack type, so that it is more convenient to carry.

Suitable for yourself, affordable, loaded with more things, good-looking, in line with your own aesthetics.

It depends on whether you travel more for short distances or carry more weight for long distances. Short-distance is generally about 30L is OK, long-distance weight-bearing, 60-70L, and the carrying system is better.

Short and medium-distance or city trips can choose a 35-40L bag with a backpack system, and the brand is not bad compared to many domestic brands, Polestar Pathfinder. There is no need for big foreign brands.
