Nanairo Monkey Bikini Brief are a vibrant tribute to pride, individuality, and inclusivity, crafted as part of Hero Colors’ exclusive limited-edition collection. These low-rise bikini briefs elevate the classic rainbow flag’s six colors with a sneaky "plus-one" shade—a premium color symbolizing love and sexuality, subtly tucked into the design with a heart motif. More than just multi-colored undies, they’re a bold yet understated statement for anyone who values self-expression and equality, day or night.

Offered in two captivating styles:

• Prism Monkey: Reflecting a prism’s ability to reveal a spectrum within light, this variant dazzles with rainbow hues and a revived "lovely" shade missing from today’s pride flags. Its playful monkey print whispers affection, making it an ageless delight for all—freeing your spirit with quirky, multi-color charm. Perfect for those who stay bold and bright at any age.


• Planet Monkey: Inspired by the universe’s boundless colors, this design sprinkles rainbow shades across a black-and-white starry expanse, like a cosmic monkey nebula. The striking pink—once a sexuality marker in the original rainbow flag—pops against the dark, mixing girly flair with masculine appeal. Cute, dreamy, and subtly erotic, it’s a cool, unique twist on pride that deepens your "under-space" vibe.

These bikini briefs marry retro-pop friendliness with functional flair. The 3D hero pouch snugly wraps everything in a single-layer front, delivering a clean silhouette and comfy hold without a front opening. Tailored for Japanese builds, the moderate low-rise cut ensures a wide range of motion and flexible support—great for active moments or relaxed days. Simple yet versatile, they’re a daily essential with color options that spark your heroic mood.

Made in Japan at Renown Inx’s Wakayama factory, these briefs showcase impeccable craftsmanship. The 95% cotton, 5% polyurethane bare jersey fabric is soft, lightweight, and stretchy, hugging your body without stress while wicking moisture for year-round freshness. The super-soft waistband (70% nylon, 25% polyester, 5% polyurethane) features brushed lining for a gentle, irritation-free fit, even after long wear. Passing Japan’s strict tests for colorfastness, shrinkage, and durability, these non-formalin briefs guarantee lasting vibrancy and safety.

Sized S to XL (waist 68–104 cm), Nanairo Monkey Bikini Brief invite everyone to wear their colors proudly. Slip into these meaningful, multi-hued undies and let your inner hero shine effortlessly!
