I often use a backpack and feel my shoulder hurts. What is better for a bag with soft shoulder straps?

Considering more comfort, the shoulder bag of 4alike black is recommended, because the shoulder width is also ergonomically designed, and the overall shape has a sense of design.

The leather bag is actually good, but it must not be pressed, otherwise the strap will crack easily. And consider it in combination with the weight of the heavy things you usually carry. If you want to carry books with you or have a lot of electronic products, I suggest you don't use leather bags, because leather bags are more decorative, belts are generally delicate, and heavy things will hurt.
