BROS by WACOAL MEN and CITEN Collaborate for New Unisex Pants

On November 5, 2025, BROS by WACOAL MEN, the men's underwear brand developed by Wacoal Corporation in Kyoto, will launch its first collaboration with the fashion brand CITEN, operated by United Arrows in Tokyo. This exciting partnership brings to market a unique, unisex pant design catered for men and women alike.

BROS by WACOAL MEN has built its reputation around the idea of comfort that men have yet to discover, focusing deeply on the materials, design, and technology that go into their underwear. The latest collaboration seeks to combine the comfort of BROS with the cutting-edge fashion sense of CITEN, a brand that has quickly gained popularity, particularly among younger consumers, thanks to its focus on e-commerce.

The Unique Features of the New Collaboration

The highlight of this collaboration is the launch of the boxer shorts, dubbed "Pantaholic," which accommodate sizes S to LL in a single design, making it an excellent choice for a wide range of body types. The pants boast an incredibly comfortable fit that envelops the body in softness. The collaboration is also unique as it features BROS by WACOAL MEN's first unisex version, providing style without sacrificing comfort.

What sets the Pantaholic apart is the striking bold inclusion of the CITEN logo on the waistband, aligning perfectly with current fashion trends emphasizing branded underwear. These stylish pants not only provide comfort but also ensure that wearers can showcase a fashionable statement in their everyday attire.

There are four attractive color options available: black, white, grey, and a vibrant yellow-green, each designed to meet diverse style preferences. The collaborative pants capture the essence of both brands—CITEN’s sharp aesthetics infused into BROS' unparalleled comfort. They fit snugly without being overly tight, utilizing a seamless construction and highly elastic material that discourages discomfort or bunching.
