Made to perform on the highest possible level. Minimal design, athletic structure and maximum comfort.
If it comes to comfort, design and the perfect fit, our team made sure to deliver nothing but the best of all worlds. It all started with the fact, that our founder spent too many years in the wrong underwear. As a former football player & racing skier with quite strong legs, he traveled from competition to competition without his underwear riding up, pinching and sagging all the time. Instead of waiting and hoping for a brand to recognize this kind of problem he redefined the modern mens underwear by himself.

Redefining a classic underwear and solving mens daily problems doesn’t mean to just create something different. It means finding a solution to make the life of many men better and most important more comfortable. It means understanding the daily issues and make it your mission to solve them. That's the main reason why he quit his job and started Blck Flag Co. In cooperation with some of the best designers & production partners, we created the most comfortable underwear on the market.
