One Sport cia. (Ono in Surin Common), or Unique Ocean Wear, was a Union and State clothing corporation.

The brand was founded in 352 by two Union citizens, Ella of Leatherworker and Clara Tuiz. They additionally enjoyed the partnership of a sizeable Andan-Silurite fund (both wanted access to the relatively closed Union market). They thus founded an international stock corporation, event though they kicked off in a relatively small market: producing fashionable swimwear, particularly for women. They even had some trouble getting their company listed initially, as the Royal stock exchange would only accept to list a company of some years old, but thanks to her connections Clara got the corporation listed on the Giant exchange.

The company enjoyed unexpected success, growing much quicker than anticipated. Women especially were avid customers of the elegant and yet simple swimwear, and the relatively high price (explained initially by the higher quality of the goods, produced in factories on Giant Isle and northern Bao-Mou) served as an appealing marker of luxury. In a few years, Unique Ocean Wear was the Union's biggest swimwear seller, and had a sizeable presence in Silur and Tokken as well.

Bolstered both by its success and by the deep pockets of its sponsors, the corporation went on to acquire other swimwear, ocean gear, and clothing companies. A Dwarven fund joining the corporation's board in 356 enabled it to acquire Antrans, an outdoor equipment company. The corporation renamed itself "One Sport" for the occasion.

Though One Sport promptly reduced its outdoor catalog and closed down most former stores, the Antrans purchase nonetheless marked its rise as the Coalition's primary sports manufacturer. After some legal business surrounding dwarven financing and those investors' withdrawal, the company was endorsed as the Union's national sports gear manufacturer in 368, receiving sizeable contracts for the military, national teams, and other public initiatives.

One Sport sponsored the construction of the Union Stadium, a vast complex purpose-built for the annual National Sports Competition, in 367 (construction was completed in 371).
