Why choose Step Ones?

Step One's are life changing underwear. Why you must ask? Here are 3 reasons why you need a pair of Step One underwear in your life:

1. Ultraglyde™ panels - these stop chafing in an instant. These panels are placed between your legs which allow your thighs to glyyyyyde with ease.

2. 3D elastic comfort pouch - the carefully constructed elastic pouch ensures all eggs are separated from the leg and don't stick, no matter the shape, or size.

3. Viscose made from bamboo material - the dreaded 'swamp ass' can finally be eradicated with the super breathable and super soft material.

Once we refined and perfected the men's range, we took some of the best features and produced our new women's range.
