YJ crafts high-performance men’s underwear tailored to your brand’s needs. Our wide range of custom men’s underwear isn’t just stylish and high-functioning, they’re built to inspire your clients to feel comfortable and confident in daily wear and special scenarios.
Everyday & Sports Men’s Underwear
We offer a premium collection of men’s underwear for daily and sports use, covering everything from breathable briefs to moisture-wicking boxers. Our products are perfect for all-day wear, gym sessions, and outdoor activities—keeping skin dry and free from friction.
Skin-Friendly Fitted Men’s Underwear
YJ extends versatile slim-fit briefs, soft loose boxers, and contouring trunks for men seeking all-around comfort. We use skin-friendly fabrics (such as combed cotton, modal, and elastic fibers) that hug the body gently, maximizing breathability and reducing tightness.
Plus-Size Men’s Underwear
Our range is designed to flatter and support men of all body types. We deliver the perfect blend of comfort and confidence with our stylish plus-size men’s underwear collection—featuring widened waistbands, stretchable fabrics, and non-restrictive cuts that move with the body.
