No friction. No chafing. No bunching.

Underwear Designed for Cycling

Shop Cycling Underwear

Cycling in regular underwear?
Don't let chafing and sweat hold you back.

❌ Painful Chafing

Cotton traps moisture and creates friction with every movement. The result? Red, raw skin that makes cycling painful.

❌ Constant Bunching

Regular underwear rides up during rides, forcing you to adjust constantly. It's distracting, uncomfortable, and ruins your rhythm.

❌ Sweat Build-Up

Cotton absorbs sweat and holds it against your skin. Heavy, wet, uncomfortable - it's the opposite of what you need on long ride.

❌ Odor Issues

Trapped moisture in cotton fabrics creates the perfect environment for bacteria. That post-exercise smell? It doesn't have to be that way.
Enjoy the ride without worrying about your underwear.

Great undies and great customer…

Great undies and great customer service. I ordered women’s full briefs in the size recommended by the size guide but they were too big. I got in touch with customer services and they were excellent; clear, quick and friendly communication and a quick exchange. The pants are excellent. I have a physical job and active hobbies like running and cycling. A lot of pants take this as an invitation to go off on adventures of their own, which is vexing. Step Ones stay put and are incredibly comfortable.

Just fantastic

Just fantastic. For someone with big legs that is always on the move, walking the dog, running around at work, out with the kids, or cycling/running for fun/charity, I’ve really struggled to find underwear that doesn’t fall apart quickly, chafe or leave me constantly rearranging. I switched to step one a couple of years ago and haven’t looked back. Highly recommend.

No jingle bells here.

Can’t praise these enough. I have tried so many different brands of underwear. Some coming close. But these just feel so comfortable either walking, running, cycling or being a lazy ass.
