First of it's Kind Design

We believe in a slow and steady mindset when it comes to design, perfecting fit and making sure our quality is up to par which is why Smooth Duo® achieves the smooth look and feel we set out to create. The built-in underwear layer of Smooth Duo Leggings comes in full coverage and thong styles and is intentionally fit and shaped for optimal comfort and ease of motion. We make sure we're using panty and legging fabric that keep you comfortable, can flex, and keep lines hidden away.

Take me to the leggings!

Supportive Legging Meet Silky Smooth Underwear

Combining our supportive and well-fit leggings with our next to weightless panty layer that's been shaped, fit and tested with care makes for this ideal duo. We were tired of wearing underwear with leggings that felt uncomfortable and and rode up so we decided to engineer a combo that would stay and move together. When no great solutions existed (and going commando wasn't always ideal!) we got to work designing Smooth Duo® Leggings and Bike Shorts with Built-in Underwear™ and manufacturing them in the USA.

Ok I'm sold. Let's shop!

Made in New York City with the Highest Standards

So many leggings are made in oversees factories at the lowest possible cost. This means quality is often sacrificed for profit (we won't name names but you know who they are 😉). We believe in creating higher quality products locally while still offering a fair price point. We believe the personal relationship we have with our vendors and the support we give one another translates into the products we offer. As a small business ourselves we want to support our local garment center in NYC and the factories and other small businesses there.

Where has this been all my life?!?!

Good news - Your leggings and underwear are already a match. Forgetting to pack workout panties in your gym bag is no longer a problem. Neither are surprise camel toes because going commando seemed like the best option. Smooth Duo® Leggings and Bike Shorts offer the best of both worlds.


Shaped not to interfere with how your body moves, our panty layer is there to offer another layer where comfort is key. We always make sure there is no bunching or riding up. Next to weightless underwear fabric stays smooth on your body.

Team THong or full coverage?

We offer a "classic fit" underwear style for full back coverage in addition to thong styles. Both fits stay incognito and are without side seams or vertical back seams giving you a smooth fit all the way through.
