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.

Fits like a glove

Super comfortable, not too tight, and doesn't give that boxy look. I've worn it to work and out to dinner, and it doesn't feel out of place in either setting.

Love wearing this

Was surprised at the quality. This isn’t athleisure stuff. This looks and fits better than my more expensive suits. It just looks and feels good from the start.

Perfect for travel

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.

    Thinning out my closet

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