The Rí Sauna Crown is built for athletes who treat recovery as seriously as training. Designed in Ireland from 100% Australian merino wool, the Sauna Crown regulates head temperature during sauna sessions - so you can stay in longer and get more from every session.Free worldwide shipping. 30-day returns.Why Your Head Heats FirstYour head sits at the highest point in the sauna - where the air is hottest - while your body is still warming up. The result: your brain tells you to leave before your muscles, joints, and cardiovascular system have had enough time to benefit. You cut the session short. Not because your body couldn't handle more, but because your head couldn't.A sauna hat changes that equation. By insulating the head, the Rí Sauna Crown lets your core temperature rise gradually and evenly, so you stay in longer, go deeper, and get more from every session. Read the full science →Why Merino WoolNot all sauna hats are equal. Cheap felt hats trap moisture and hold heat against your scalp. The Rí Sauna Crown is made from 100% Australian merino wool - a natural performance fibre trusted in endurance sport, mountaineering, and extreme-weather gear. Temperature regulation. Merino insulates without overheating. It buffers your head from the most extreme air temperature while allowing gradual, controlled warming. Moisture-wicking. Merino pulls sweat away from the skin and releases it as vapour. No soggy hat, no dripping forehead. Naturally antibacterial. Merino resists odour-causing bacteria, so the Crown stays fresh between washes. Breathable. Unlike synthetic or dense felt, merino allows airflow. Protection without suffocation. Durable at high heat. Rated for 80-100°C - traditional saunas, infrared cabins, and steam rooms. Your Sauna Crown Protocol Place the Crown on your head before entering the sauna. Pull it down to cover your ears if you prefer extra insulation, or wear it higher for a lighter feel. Stay longer. With your head insulated, you can comfortably extend your sessions. Start with your usual duration and add 2-5 minutes as you adapt. Combine with cold exposure. Many athletes alternate sauna rounds with cold plunges. Keep the Crown on during sauna rounds and remove it during cold exposure for maximum contrast. Rehydrate. Longer sessions mean more sweat. Drink water before, during, and after. One size fits all. Merino wool naturally conforms to your head shape after 1-2 sessions.Care: Hand wash in cool water, reshape, lay flat to dry. Never tumble dry.Download the free Rí Sauna Optimiser - 6 research-backed protocols →Shipping & Returns Free worldwide shipping on every order. No minimums.
