With hundreds of sauna hat options available, experts recommend considering four key factors:

1. Material: Wool felt vs. linen vs. cotton
2. Fit: Adjustable bands vs. fixed sizes
3. Purpose: Home use vs. professional spa
4. Care requirements: Machine-washable vs. hand-wash only

“Your sauna hat should feel like a second skin,” advises spa consultant Laura Bennett. “For first-time buyers, we recommend starting with a medium-weight wool felt sauna hat – it offers the best balance of protection and breathability.”
