When it comes to protection and sweat prevention, I think talking is better than nothing.
First of all, China people's wrists are not as thick as old black and white, so they can't be tied up, so you will feel loose.
Old black, they still have some effect with this.
1, because they can dunk, their wrists will touch the basket when dunking, and sometimes there will be scratches, so this directly plays a certain protective role.
2. Because the wrist is thick and tight, the sweat will not flow directly to the palm along the arm, but will be "cut off" by the rubber ring. This can reduce palm sweating to a certain extent, which is beneficial to ball control.
We bring it, it's just in the way.
If it looks good, it's not bad
