Your head overheats before your body does - it's why most people quit the sauna early. The Crown regulates head temperature so your body decides when to stop, not your head. The result: longer sessions, deeper adaptation, more benefit.

Our Mission
Temperature is the last untapped frontier in sports performance.
Strength has been measured and tracked for a century. Skill has been filmed, analysed, and rebuilt from the ground up. Nutrition has been debated into a science, and recovery is now a calendar appointment. The one variable that sits underneath all of it, the one every culture from Finland to Ireland has intuited for a thousand years, is the one sport has barely started to think about: temperature.
A body in full effort works like an engine. It rarely quits because it runs out of fuel, or because the legs stop turning over. It quits because it overheats. The head sits at the top of the system and heats first. The body registers the signal, protects itself, and the session is over before the work is actually done.
Rí is a series of products built to optimise for temperature, one chapter at a time.
Chapter One
The Sauna Crown
A merino wool tool that keeps the head cool so the body can stay in the heat long enough for real adaptation to happen. Chapter Two is already in the works.
