Feel great, all-day

A great day starts with your underwear

Debriefs are made with MicroModal - a moisture-wicking, breathable fabric that works naturally to keep you feeling fresh and comfortable. It's sustainably sourced and superscedes all the natural benefits of cotton.

How underwear should be

Supportive & practical

Every pair features an anatomically correct pouch that gently cradles and supports the twins throughout the day. Reinforced leg hems also prevent ride-up, so no more chafing. And a horizontal fly makes it super easy to free willy when nature calls.

A supreme cotton alternative

MicroModal™ vs Bamboo

Both are natural fibres and feel similar in texture and softness. However, MicroModal is stronger and more absorbent meaning it's more durable, and better at wicking moisture away from your skin.

We source our MicroModal from Lenzing in Austria, and the undies are produced in our GOTS certified factory in Turkey.
