The wellness world is divided over what constitutes the ideal sauna hat material. We commissioned an independent lab to test the three main contenders under controlled sauna conditions:

Wool Felt (Traditional Choice)
Pros:

• Superior temperature regulation
• Natural moisture management
• Longest lifespan (8-12 years)
  Cons:
• Higher initial cost
• Requires careful cleaning

Linen (Modern Favorite)
Pros:

• Lightweight and breathable
• Quick-drying
• Naturally antimicrobial
  Cons:
• Less thermal protection
• Wears out faster (3-5 years)

Cotton (Budget Option)
Pros:

• Affordable
• Easy to clean
• Widely available
  Cons:
• Poor heat resistance
• Can overheat scalp

“Material choice depends on your sauna style,” concludes researcher Dr. Emma Lindgren. “Frequent infrared users need wool’s protection, while occasional steam sauna visitors might prefer linen’s breathability.”
