It is soft and comfortable
The upper body of the strap is very effective, but I personally feel that the stretchability is not very strong, there is no particularly strong sense of restraint, it is the elasticity of a small rubber band, after all, it is an invisible model, and it will not stretch the back very much. It is suitable for daily wear without too much burden. The material of the shoulder strap is very comfortable, without the burden of tightening, it is soft and comfortable.
