Real use backpack to buy

The advantages of the backpack, free hands, balanced load, and large load. The shortcomings of the backpack: convenient access, anti-theft, appearance, etc. are not as good as the shoulder bag, chest bag, waist bag, hand bag, upper arm bag, thigh bag. So, if you choose a commonly used backpack, we temporarily think that the usage scenario is city commuting on weekdays plus short light outdoor on rest days, and city/outdoor travel on holidays.

1. Waterproof (splashing): no water in the rain bag
I have put this on the first one and I am ready to be sprayed. After all, the bags on the market are almost all waterproof. However, after all, the appearance of water-proof, water-repellent, and water-repellent is different. First of all, if you see bags made of nylon, ballistic nylon, cordura (roasted sweet potatoes, Cordura), and polyester fabric on the market, you can consider them to be water repellent. What does this water repellent concept look like? When closed, pour a 500ml bottle of drinking water on the bag, and then shake off the water on the bag. The paper products in the bag will not be wet but may be damp, and no water droplets will be seen in the bag; no umbrella is brought when it rains heavily , Walked to the rain shelter within three minutes under the rain, there will be no drops of water in the bag. When you see clothing fabrics such as cotton and denim, you need to be cautious. These bags are generally good-looking, high-valued, and claim to be waterproof, but untreated such fabrics are either deadly or poorly waterproof. Of course, feelings, The choice between looks and shoulders is still a very personal topic.

2. Notebook cabin/water bag cabin (also has bonus points, but unfortunately I have never seen it before): the guy who eats is placed alone

When the Swiss Army Knife series of backpacks became popular, the notebook compartment became the basic configuration of the backpack. At present, almost all the backpacks on the market and the business word have such a notebook compartment, which is generally close to the back. Outdoor backpacks, basically all equipped with a water bag compartment that can be used on the countertop. Moreover, as a person with a pit in my head, I sometimes like to climb mountains with my laptop on my back, so I wanted to find a backpack with both a laptop compartment and a water bag. This attempt naturally failed. The solution is the water bag compartment of the outdoor bag and the optional notebook liner bag. In order to emphasize the importance, I repeat it again. Notebooks are productivity tools and water is life-saving, so these two compartments are very important.

3. Carrying: wide strap foundation, back diversion bonus points, adjustable waist seal and inner frame back diversion ideal
Putting it aside 25 years ago, carrying? A backpack would be great; I put it on my back 20 years ago? A wide strap would be nice. So, how did you memorize such heavy books and workbooks when you were in school? Cure all diseases: a strategy for purchasing a backpack with (nan) (kan) Wide straps are the basis for carrying. The wider the straps, the lower the pressure on the shoulders, and the more comfortable the carrying. Wearing it for a long time makes the back sweat prone, so the back diversion system, or I call it a life-and-death can not fully stick to the back, must have a passing wind, which can be a little more comfortable, but under the 38 degree sun, sweating is inevitable. For outdoor bags, during the carrying process, the gluteus maximus muscles bear most of the weight of the backpack, which comes from the function of the waist seal and has a miraculous effect on reducing the burden on the shoulders. However, the pure business bag seems to have never seen a girdle. The following pictures show the width of the shoulder straps of a few backpacks that I have good condition and not used frequently, for your reference.

4. Separation: detailed, practical and easy to find
When it comes to separation, the Swiss Army Knife is really inevitable. When choosing a package, about the separation, just ask yourself: What do you have, what do you want, can you have what you want, can you put it in that bag, and can you find it after you put it in that bag? After putting it in the bag, what space is left in the bag. By the way, I knelt on the washboard twice recently because I put the social security card in the bag, then the washing machine, and once I put the supermarket card in the trouser pocket, and then the trousers were put in the washing machine to cure all diseases: Real (nan) use (kan) backpack purchase strategy.

What does the separation look like? What I like is: the main cabin and the auxiliary cabin, the notebook digital tablet cabin, and it is best to have the external side pockets for the cups and water bottles.

5. The shape of the main cabin: more squares are installed
This one was carried out separately because the shape of the main cabin obviously affects how much it can fit. This is quite obvious when moving the cubicle, shopping in the supermarket, or giving snacks to girls on short trips outdoors. The shape of the main cabin is related to the stitching of the fabric and the position of the zipper. Personally, I would recommend the square main cabin, although it looks like it`s carrying a few bricks on its back. It is common in the market to have a closed design on the top of the main cabin, which is beautiful in appearance and may save fabric.

6. 180-degree opening and closing of the notebook compartment: the notebook cannot be shipped out after the security check;
Friends who have gone through the airport security check should be impressed by this scene. Of course, whether you need to add such a thing to your backpack, different people have different opinions.

7. The capacity can be expanded: the supermarket tool;
It`s best to have a bag that can hold things when you move, but no one will carry a large 85L rucksack for daily commuting and prepare a lot of things for temporary needs. At this time, the capacity can be expanded to show its usefulness, and one more shopping bag can be installed out of thin air. However, if you install more out of thin air, the loss of the bag is not small. The bag that I can expand the capacity on hand has been used for four or five holes. Of course, if there is no such function, there is no problem. After all, we have folding bags to choose from, such as the following. The name of C2 is getting worse and worse.

8. Horizontal and vertical double handles: do not mop the floor by hand;
We can't rule out the situation where we can't bear it, that is, when we need to carry it by hand. The shoulder strap adjustment strap may mopping the floor when carrying the top of the backpack and walking. We will not talk about hygiene and aesthetics here. The mopping backpack strap may be stuck in the gap of the escalator, tripping pedestrians or even yourself before and after. It is a safety issue. The decisive way is to tighten the adjustment belt. However, this thing has only been seen in outdoor bags (I am lonely, welcome to list the brand models to face). So the other way is to carry it sideways, that is, multiple handles.

9. The hole that can be set in the trolley case: the gratitude for the achievement of shoulders and necks;
There are too many bags on my back, sometimes I really want to be able to carry it without carrying it, especially when waiting for transportation at the airport station. Therefore, it is a very happy time to be able to fit with the trolley case. Xiaomi called him a rear cart strap.
