Our revolutionary Jon dress pant will change your life. Made from a premium 14-ounce stretch fabric, it feels and looks refined enough for the boardroom but has the flexibility of an athletic pant.

The Jon is more than stretchy enough to wear to the gym and will be your new best friend next time you’re sprinting to catch the subway. We designed the Jon to fit you perfectly off the rack; a clean silhouette with a sharp taper down the leg to look great with sleek dress shoes.  

Pair it with our white stretch dress shirt for an outfit as relaxing as your vacation days!


Runs slimmer than our other pants. Our recommendation: For thin builds, order your normal waist size. For average or athletic builds, size up one waist size. If you are brawny, size up two waist sizes.

It’s so great to find pants that fit without having to go to the tailor. These are very comfortable, I often wear them when I travel and have no complaints.

Simply the best pants. Ever.

These pants are not only ultra comfortable and feather-like light weight stretch, they also are machine wash and don’t get creased when I fall asleep ***** af in them! That’s right, I’m still looking crisp the next day at the corporate round table closing every deal even after sleeping in these bad boys. Thanks Under510!!
