I asked an instructor about brands, and he recommended Rival. They seem popular online too, based on some old Reddit threads.

At Rival, the belief is that while other companies are businessmen trying to infiltrate the boxing world, Rival is proud to be boxing people trying to infiltrate the business world.

Everybody that works for Rival is, in one way or another, connected to boxing. As a result, Rival’s product ranges are created from a boxing perspective and the company takes real pride in its designs, technologies and innovations.
