Keep it long, treasure it long.

Silky smooth texture

A dependable pair of boxer briefs designed for those who want to feel comfortable and true to themselves—even in the seasons when sweat can make freshness feel out of reach.

What sets this piece apart is its use of innovative materials that naturally neutralize unpleasant odors. From sweat-induced smells like ammonia and acetic acid to age-related body odor (nonenal), these boxer briefs tackle them all. What’s more, the deodorizing properties are reactivated with every wash—so the more you wear and launder them, the more you’ll experience their impressive functionality. Crafted with a gentle touch against the skin, this is a technical garment that’s mindful of both your comfort and the environment.

Key Features

The fabric features NEUTRALWORKS’ signature "FINE DRY" material—a blend of silky-smooth rayon and high-performance deodorizing fiber, Maxi Fresh. This combination strikes the perfect balance between functionality and softness. Thanks to the microfiber composition, these briefs offer exceptional smoothness and stretch, ensuring ease of movement and long-lasting comfort throughout the day. They also excel in moisture-wicking and quick-drying, keeping you dry and fresh no matter what the day brings.

Perfect as a thoughtful gift or a personal upgrade—this understated yet premium piece suits anyone who values care even in the details others can't see.

Connecting Activity with Everyday Life

From the moment you get dressed in the morning to commuting, working, squeezing in a workout at the gym, and winding down at home—NEUTRALWORKS creates items designed to seamlessly connect the active and the everyday.
The concept is reflected in its clean, minimalist, and unisex design. By stripping away unnecessary embellishments, the brand makes it easy for anyone—regardless of age, gender, or lifestyle—to live authentically and comfortably.

Shaping the Future

Brought to life by Goldwin, a company with a deep legacy in sports apparel, NEUTRALWORKS is built on the concept of helping people "maintain physical and mental balance through a sports lifestyle, 24/7." The brand revolves around four key themes: MOVE, WORK, SLEEP, and NSKIN—offering functional, sustainable products made with care for both people and the planet.

MOVE: Activewear equipped with features like quick-dry and odor control

WORK: Smart, comfortable clothing for productive work hours

SLEEP: Recovery-focused sleepwear developed with medical doctor Kiyonaga Shimizu

NSKIN: Apparel that shields the body from UV rays, temperature extremes, and friction

The brand inherits its technology from MXP, a pioneer in deodorizing performance wear, and officially merged with NEUTRALWORKS in 2022. With Dr. Shimizu—a medical doctor and professor emeritus at Osaka Prefecture University—overseeing product development, each item is built on both scientific data and real-world feedback, ensuring unmatched quality.

Ultimately, NEUTRALWORKS is about more than clothing. It’s about supporting a lifestyle where you can go where you want, when you want, and be your best self—by staying physically and mentally optimized. That’s why the brand aims not just to sell garments, but to enhance the in-between spaces—between people, objects, society, and the environment.
