About us

Founded in 2008, Siven Sport Ltd began as a passion project—creating high-performance kits for local orienteering teams. But our roots go even deeper. Our founders were the first producers of orienteering sportswear in Bulgaria, pioneering the way for specialized athletic gear in the country.

Today, under our brand name Bryzos, we continue to push the boundaries of performance-driven, custom sportswear. Over the years, we’ve grown from a small initiative into a trusted name, collaborating with event organizers, sports federations, non-profits, and team representatives to deliver high-quality apparel tailored to the demands of both elite competitors and enthusiast teams.

Our mission remains the same: to create durable, high-performance sportswear that empowers athletes, strengthens team spirit, and withstands the toughest conditions.

Built for athletes. Designed for teams. We are Bryzos.
