Because your crown deserves proper care.
Your ETERNA sauna hat is crafted from 100% Australian merino wool, a natural performance fiber traditionally used in Nordic saunas to protect the head from extreme heat.
Merino wool is naturally:
• Antibacterial
• Odor resistant
• Moisture wicking
• Temperature regulating
Because of these natural properties, your sauna hat rarely needs washing. Most of the time, simply airing it out is all it needs.
After Each Sauna Session
- Air Dry
After use, hang or place your hat in a well ventilated space and allow it to dry completely. - Avoid Enclosed Spaces
Do not leave the hat in a gym bag, locker, or sealed container while damp. - Let the Wool Reset
Merino fibers naturally release moisture and odors when exposed to fresh air.
When to Wash
Your hat only needs washing occasionally.
General guideline:
• Every 10 to 20 sauna sessions
• Or when visibly soiled
Frequent washing is unnecessary and can shorten the life of the wool.
How to Wash Your Sauna Hat
- Hand Wash Only
Use cool or lukewarm water
(max 30°C / 86°F) - Use Mild Detergent
A gentle wool or delicate detergent works best.
Avoid bleach or harsh cleaners. - Do Not Scrub or Twist
Gently press the hat in the water rather than rubbing or wringing. - Rinse Thoroughly
Rinse with clean water until soap is removed. - Press With a Towel
Place the hat in a towel and press gently to remove excess moisture. - Lay Flat to Dry
Allow the hat to dry naturally in the shade.
Avoid dryers or direct heat sources.
Storage Tips
• Store fully dry
• Keep in a cool, ventilated space
• Avoid compressing the hat for long periods
