Mister B Leather FXXXer Jeans All Black

Premium leather jeans with a pouch that pops

Step into the Mister B Leather FXXXer Jeans Black, and get ready to put your package front and centre. Designed with a fixed, ultra-visible pouch, these low-rise leather trousers accentuate your bulge, frame your backside, and contour to your thighs in all the right ways. With contrast piping across the pouch, seams, ass saddle and pockets, they give you that hyper-masculine, dominant silhouette every leatherman dreams of.

These jeans are handcrafted in Mister B’s own European leather workshop from 100% aniline full grain cow leather (1.0–1.1 mm thick). The leather is strong, yet softens over time, making them a perfect fit after just a few wears.

Built to show off, designed to last

The Leather FXXXer Jeans feature bold, decorative piping that runs along the front pouch, leg seams, pockets and ass panel, giving structure and drawing attention to every curve. With 2 zippered front and back pockets, double-stitched belt loops (fits belts up to 5 cm), and that signature tight fit, these jeans aren’t just about the look—they’re about the lifestyle.

Choose from Black leather with piping in Black, White, Grey, Blue or Red—or opt for Grey leather with Black piping. For full customisation, including alternative leathers, piping colours and stitching options, visit our Mister B brandstores in Amsterdam, Berlin or Antwerp, or head to our concept stores in Oslo, Copenhagen, Dortmund, Cologne, Frankfurt or Melbourne.

Leather that moulds to your body

Leather is a living, breathing material, and Mister B treats it with the respect it deserves. Your new FXXXer Jeans will feel snug on first wear—intentionally so. After 2–3 uses, the leather starts to mould to your body, giving you a tailored fit that’s yours and yours alone.

These jeans follow standard jeans sizing from 29–38 inches, but the leather means they fit tighter than denim. If you're between sizes or prefer a looser fit, we recommend sizing up. For the best fit, visit one of our stores for a personal fitting. We also offer complimentary leg finishing in-store (not available online).
