    8-way stretch technology

    More comfortable than your tracksuit.

    It's why Forbes calls xSuit “the most comfortable, everyday, and everywhere suit.” Our proprietary fabric is much more expensive to produce than other stretch fabrics—because it maximizes stretch, shape retention, and breathability.

    Advanced nanotechnology

    Stain-resistant.

    Thanks to industry-leading nanotechnology, liquids roll off the xSuit 4 without leaving a trace. Machine-washability also makes the xSuit 4 quick and easy to maintain—without ever needing to pay a dry-cleaning bill.

    Durable fabric construction

    Machine-washable.

    Toss the xSuit 4.0 into your washing machine and call it a day. Never waste money or time on dry cleaning again.

    Packable, wrinkle-resistant fabric

    The ultimate travel suit.

    Throw the xSuit 4 into a suitcase, gym bag, or backpack without a second thought. No iron, steamer, or suit bag required. Our revolutionary fabric technology releases wrinkles and retains shape—for sharp and defined structure, always.

    Thermo-fused, reinforced seams

    Lasts 5x longer.

    We fuse our seams together in a rare process that takes four times longer than regular stitching. The result: seams that remain flat and smooth, and a durable suit that maintains its shape and lasts five times longer.

    Yarns Composition & Knit Constructions

    Made for Motion.

    Our fabrics are made with specialized Japanese yarns blends and innovatives knit. We select the best yarns that offer stretch, breathability and softnesss properties to prioritize comfort above all - Rayon/Viscose, Spandex/Elastane, Nylon/Polyamide. Yarns are then knitted together by Ponte Warp Knit to provide the perfect balance of structure.

    Premiums Testing

    Durability & Performance.

    Our products are engineered to perform, and are built to last. We achieve this through rigorously testing our products both in the real world and the lab - Color fastness, Shrinkage, Repellency, Abrasion, Tensile strenght, Pilling, Tear strenght, Breathability, Crease recovery.

      Great pants

      Lovely pants. Great stretch fabric, feels like pajamas. Little things like the inner pocket make so much difference.

      Best pants ever!

      These are hands down the most comfortable, light weight, soft, fresh and stretchy pants I have used in my entire life for a suit. Too bad they are gone now, the 5.0 is wool, so they are hot and itchy; I will miss the 4.0 pants and they will probably be my last purchase.

      Thinning out my closet

      It just goes with a lot of shirts and ties so I can make less, more.

      Exceptional Quality and Style

      I recently purchased the xPant 4.0 Dark Blue suit, and I must say, it exceeded all my expectations. The craftsmanship is impeccable, showcasing a perfect blend of modern style and timeless elegance. The dark blue color is rich and versatile, making it suitable for both formal events and more relaxed occasions.

      The fit is spot on, offering a tailored look right off the rack. The fabric feels luxurious and comfortable, allowing for ease of movement without compromising on style. Every detail, from the stitching to the buttons, speaks to the high quality of this suit.

      Given that this was a final sale, I couldn't be happier with my purchase. The xPant 4.0 has quickly become my go-to suit, and I have received numerous compliments every time I wear it. If you're looking for a standout suit that combines sophistication with comfort, I highly recommend the xPant 4.0 Dark Blue. It's truly amazing!
