Engineered to Optimise.

  • Biological Climate Control

    Natural fibres actively manage heat and moisture. Optimal temperature regulation protects performance and fertility.

  • Zero-Friction Support

    Contoured fits and ultra-soft materials engineered to eliminate ride-up and chafing, from the squat rack to the 12-hour workday.

  • The Natural Advantage

    Ditch the synthetics. We use high-quality, durable bamboo and modal materials that perform without compromise.

The Performance Game is Rigged.

We didn't just build a better base layer, we built a necessary one. The industry sells you heat-trapping polyester rebranded as "performance." We built BSCO to challenge that lie. 

Your health and fertility are non-negotiable assets. We use the best natural materials to deliver constant airflow, superior support, and zero friction, so you can focus on hitting your next goal, not managing discomfort.

We protect the foundation of your performance.
