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.

Best suit I've ever purchased!
It is now one of my favorite suits in my closet. Solid built, comfortable to the touch. Perfect for business travel with all of the pockets and durability.
Worth every dollar
Great customer experience. Amazing suit. I can’t believe a suit I bought off the internet can fit so well. Comfort and stretchiness were not oversold. I’m a huge fan.
This suit is by far the most comfortable and best fitting I’ve ever owned. It almost feels like I’m wearing a tracksuit. I truly recommend it.
