What does a good backpack look like?
There are thousands of shoulder bags on the market, but those that can really accompany you for a long time often have these characteristics:
Comfortable carrying system
This is the “soul” of the backpack. A good shoulder strap should be widened and thickened, which can effectively disperse the pressure; the back should have a breathable mesh surface, which will not be stuffy and sweaty in summer; if you often carry heavy objects, the design of mountaineering bag with chest buckle and waist buckle will be a better choice.
Try to recite tips: load a few books in, walk around the store twice. Feel whether the shoulder strap is stuck in the neck, whether the back is breathable, and whether the bag body is close to the back.
Reasonable zoning design
A good backpack should be like a competent packer:
Separate computer compartment: With shockproof cotton to protect your productivity tools
Quick access to the front pocket: put paper towels, headphones, traffic cards, and take them with you.
Concealed back pocket: mobile phone, passport, anti-theft and convenient
Side pocket: water cup or umbrella, ready to use
Durable material
Backpacks are “consumables” that are used every day, and the material determines how long they can stay with you.
Nylon: Lightweight, wear-resistant, waterproof, is the first choice for commuting
Canvas: Retro texture, but afraid of water and dirt
PU leather/genuine leather: high appearance, but heavy weight, suitable for light travel
Ballistic Nylon: Military grade, extremely wear-resistant, ten years is not a problem
Just the right capacity
Capacity is not the bigger the better. If the bag is too big, you will unconsciously stuff things into it, and finally you can’t carry it on your back.
Under 15 L: Mini bag, suitable for going out with only mobile phone wallet
15-20 L: Gold capacity for daily commuting, able to hold 13-inch computer + personal belongings
20-30L: Short trip or scene with a lot of documents to memorize
More than 30L: special for outdoor hiking and long-distance travel
