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.

Ultra comfortable

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.

    Better than the 3.0 suit

    The dark blue looks very professional, fits true to size, and shoulder pads are placed more naturally so it doesn't look like a stretchy suit.

    Excellent product

    I had an issue with the delivery with the first suit but I reached out to customer service and they seem to get me a new suit shipped within a couple of days. Customer service was excellent. And the suit was super comfortable and fit wonderfully. I normally do not wear suits but am able to enjoy wearing this one for the due to the comfort and fit.
