What makes Step Ones special?

Ultraglyde™ panels

These friction resistant panels come with anti-chafe technology, so they prevent leg ride up and stop those awkward moments of re-adjusting in public!

3D comfort pouch

There’s a hidden piece of elastic around the pouch to surround you and your boys perfectly, keeping everything neatly in place!

Super soft bamboo viscose

This organic material, produced in a close-loop system, wicks away sweat and moisture and allows you to breathe all day long!
