Wool Felt

The classic #1 choice for sauna hats. Thick felted sheep's wool provides excellent thermal insulation and can withstand very high sauna heat. Wool can soak up ~30% of its weight in water vapor while still insulating. Naturally antibacterial and odor-resistant.

Pros

  • +Excellent insulation
  • +Durable
  • +Natural antibacterial properties
  • +Holds shape well

Cons

  • May feel warm initially
  • Some people sensitive to wool

Alpaca

A premium material prized for being lighter yet equally insulating than sheep's wool. Alpaca fibers are partially hollow, trapping more air for top-notch heat protection with less weight.

Pros

  • +Hypoallergenic (no lanolin)
  • +Ultra-soft
  • +Lightweight
  • +Excellent insulation

Cons

  • Higher price
  • Less elastic than wool

Linen

Made from flax plant fibers, linen hats are breathable and lightweight. Best for moderate-temperature saunas or for people who find wool too warm.

Pros

  • +Very breathable
  • +Quick drying
  • +Gets softer with washing
  • +Vegan-friendly

Cons

  • Less insulating
  • Not ideal for high-heat saunas

Cotton

Cotton saturates quickly with sweat and loses all insulation when wet. A soaking wet cotton hat can trap heat and make your head feel even hotter.

Pros

  • +Soft
  • +Affordable
  • +Easy to wash

Cons

  • Poor insulation when wet
  • Loses shape
  • Not effective for sauna use

Our choice: All Aura Sauna hats are made from wool felt—the material that's worked for hundreds of years in Finnish and Russian saunas.
