Their description of the company states:
"Launched in June 2010, Zumo men's water polo swimsuits quickly gained an enthusiastic following. USC, Cal, UCLA, and UC-Davis all wear Zumo custom-designed suits. Tony Azevedo, Olympian and USA National Team player, represents and endorses the Zumo brand. Players in the USA, Europe, and New Zealand buy Zumo products and refer their friends.
Zumo is very grateful, and here are a few reasons why water polo players chose Zumo. Located just south of San Francisco, California, Zumo is a boutique water polo apparel manufacturing company that makes all of its water polo swimsuits by hand in the USA. Zumo suits stand out because in addition to being durable, they are made with vivid color, unique and stylish graphic designs, and luxurious fabric.
Zumo - made in California, worn by everyone."
