Ice where it counts

A custom reusable cold pack slides into a hidden pocket. Published research supports scrotal cooling for healthy sperm production and quality. We made it wearable.

Sauna fabric
THE FABRIC PROBLEM

Cotton traps what your body is trying to release

In a sauna, your skin is pushing out toxins through sweat. Cotton absorbs that sweat and holds it against you. TENCEL fibers do the opposite. It wicks moisture away from the body and releases it.

THERMAL ENGINEERING

Built to breathe, not trap

Most boxer briefs create a heat pocket against the body. Ours use an open-knit TENCEL construction that allows airflow where it matters most. You'll feel the difference in the first hour.
