Introducing Poten & Rostersox

Introducing Poten & Rostersox

Iguchi Hironobu, the man behind Poten and Rostersox, is a baseball fan.

A really, really big baseball fan. After growing up playing baseball as a child in Japan, he went on to play baseball in college, and then as a professional in the Japanese minor leagues. He is also the proud owner of one of Japan’s largest collections of baseball cards. The guy loves baseball.

Hiro translated this love of baseball into fashion industry success, founding his company Gwynn in 2012 (we couldn’t confirm, but we think the company name is probably a reference to San Diego Padres legend Tony Gwynn). Under the Gwynn umbrella, Hiro has several apparel and accessory brands, as well as the store Tamaniwa in Tokyo’s Ebisu district. Preeminent in the Gwynn universe are Poten and Rostersox, two brands responsible for some of the best accessories we’ve ever laid eyes on.

Poten’s origin story has become something of a cult legend among hat connoisseurs, a testament to Hiro’s love of baseball and sheer determination. It all starts with a factory in Japan. This factory is the official producer of baseball caps for Japan’s major league, Nippon Professional Baseball (NPB), and they make caps for no one else. Many brands have tried and failed to make caps at this factory, but Hiro refused to take no for an answer. Every three months for three years straight, he would visit the factory and attempt to convince them. Presumably exasperated and impressed by Hiro’s relentlessness, the factory eventually agreed to produce Hiro’s baseball caps.

The hard work paid off, because Poten’s baseball caps are undoubtedly the best in the biz.

The build quality is unbelievable and the vintage-inspired silhouette is endlessly wearable. The brims are wide and subtly curved, while the leather headband, leather strap, and medium depth crown ensures a perfect fit on all head shapes and sizes. Arguably the best part is the fabrics, ranging from technical water repellent nylons to rich corduroys and velour.

Rostersox is a similar beast, treating socks with the same respect that Poten treats baseball caps.

Each pair is made in Japan and they often reference collegiate style, Americana, and of course, baseball. The colours are playful, the materials excellent, and they’re just straight up the most comfortable socks we’ve ever worn. In our opinion, Poten and Rostersox stand alone at the top of the accessory game. They’ve quite literally got you covered from top to bottom.
