Description

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.

Why Your Head Heats First

Your head sits at the highest point in the sauna - the hottest air hits it first. Your brain tells you to leave before your muscles, joints, and cardiovascular system have had enough time to benefit.

The Rí Sauna Crown insulates your head so your core temperature rises gradually. You stay in longer, go deeper, recover better. Read the full science →

Why Merino Wool

  • Temperature regulation. Insulates without overheating.
  • Moisture-wicking. Pulls sweat away - no soggy hat.
  • Antibacterial. Stays fresh between washes.
  • Breathable. Airflow, not suffocation.
  • Durable. Rated for 80-100°C.

Your Sauna Crown Protocol

  1. Wear it in. Place the Crown on before entering. Cover your ears for extra insulation, or wear it higher for a lighter feel.
  2. Stay longer. Start with your usual duration and add 2-5 minutes as you adapt.
  3. Combine with cold exposure. Keep the Crown on during sauna rounds, remove it during cold plunges.
  4. Rehydrate. Longer sessions mean more sweat. Drink water before, during, and after.

Size & Fit

One size. Fits 54-62cm head circumference.

Merino wool has natural stretch and memory - the crown moulds to your head over the first few sessions. If you're between sizes, size down for a closer fit.

Measure: wrap a soft tape around your head, just above the ears and eyebrows, where a hat would sit.

FAQ

Why merino wool and not traditional felt?
Merino insulates without absorbing steam. Felt gets heavy, develops odour, and can't be machine washed. Full breakdown here.

Can I machine wash it?
Yes - cold, gentle cycle, wool setting. Reshape and lay flat to dry. Never tumble dry.

Will it shrink?
Not if you follow the care instructions. Hot water and tumble drying will shrink any wool.

How hot can it handle?
Merino tolerates Finnish sauna temperatures (80-100°C) without damage. We've tested it well beyond.

Does it smell?
Merino is naturally antibacterial and resists odour far longer than cotton or synthetic hats.

Where is it made?
Designed in Ireland. Australian merino wool.

The Science

Merino wool is the only material that wins on insulation, moisture management, odour resistance, and washability. Research in the Textile Research Journal has shown wool fibres can absorb up to 30% of their own weight in moisture before feeling damp - no synthetic or plant fibre comes close.
