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.

Repels liquids like magic.

Less stains, less odors, less need to wash. Thanks to industry-leading nanotechnology, liquids roll off the xSuit 4.0 without leaving a trace.

Wash from home.

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

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.

Never worry about rips or tears.

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.

    Great for travel or everyday wear

    Needed a new suit for travel, a wedding and a Bat Mitzvah. Couldn't be happier with the fit, quality and comfort of the XSuit. Runs true to size and can be worn all day doing anything and feels great. Packed in my suitcase for international travel and could be worn without ironing.
