Why we made them

The briefs we didn’t want to make.

We held out on briefs for years. You kept asking, so we made a small run and it sold out. Second run: same bamboo viscose, same 3D Comfort Pouch, same classic cut, back in three colours and limited numbers.

In a customer’s words
  1. “I’m so glad they started making men’s briefs, even if they didn’t want to! Consider me a guaranteed customer for new brief styles.” Aubs

The timeless silhouette: all the support, none of the leg. Maximum freedom of movement, all day.

Anatomically designed pouch keeps everything separated and supported, reducing friction and sweating.

Organically grown bamboo viscose that’s incredibly soft, breathable and naturally sweat-wicking.

A super soft waistband that sits flat and doesn’t roll, so nothing needs adjusting.

Questions, answered.

What are Step One Briefs made of?

They are made from high-quality, organically grown bamboo viscose. This material is incredibly soft, breathable and moisture-wicking, keeping you cool and dry all day long.

How do Briefs differ from Boxer Briefs?

Briefs give you the classic cut: all the support with none of the leg length. You get the same bamboo viscose fabric and 3D Comfort Pouch as our Boxer Briefs, in a timeless silhouette with maximum freedom of movement.

What is the 3D Comfort Pouch?

Our 3D Comfort Pouch is anatomically designed to keep everything separated and supported. It reduces skin-on-skin contact, friction and sweating, giving you the support you need without feeling restricted.

How does the First Pair Guarantee work?

We are so confident you’ll love your first pair of Step One underwear that if you don’t, you can keep them and we’ll give you a full refund. No questions asked. This applies to your first single pair purchase.

How should I wash them?

Machine wash cold with like colours. Tumble dry low or line dry in the shade. Do not bleach, iron or dry clean, to maintain the quality of the bamboo fabric.
