Disclosure: this site is operated by the team behind DIVELUX, so we make one of the two hats in this comparison. Everything below about Halsa comes from Halsa's own product pages and its Amazon listing; where Halsa is the better choice, we say so.
DIVELUX and Halsa are the two wool sauna hat brands American shoppers compare most often. Both sell 100% wool felt hats, both cost about $20 for the basic model, and both fit heads up to 24 inches. The real differences are felt thickness, shape, range of designs and who you're buying from. Here they are side by side.

Where Halsa is the better choice
- Design range. Halsa sells far more styles: checkered, floral, pink scalloped, a captain hat, a Viking hat, a mushroom hat, beanies and a merino model. If you want a fun gift or a hat that stands out in a group sauna, Halsa has more to choose from.
- Merino option. Halsa offers a 100% merino wool hat. Merino is finer and softer, which matters if regular wool feels scratchy on your skin. DIVELUX doesn't make a merino hat.
- A lighter hat. At 2 mm, Halsa's bucket hat is lighter and packs flatter, which some people prefer for the gym bag or for milder, shorter sessions.
- More ratings on the bucket model. Halsa's bucket hat has 345 Amazon ratings against 206 for DIVELUX.
Where DIVELUX is the better choice
- Thicker felt. About 4–5 mm against 2 mm. Felt thickness is what decides how long your head stays comfortable on the top bench of a hot Finnish sauna or a banya. More on why in Felt Thickness: The Millimeters That Decide How Good a Sauna Hat Is.
- The classic banya bell. The bell shape covers the ears and the back of the neck and dries on its loop. Halsa's comparable everyday hat is a bucket.
- Most bought on Amazon. DIVELUX is the #1 Best Seller in Sauna Accessories on Amazon and has Amazon's Choice; Halsa's bucket hat ranks #7 in the same category.
- Same price for more felt. Both cost about $20; with DIVELUX the money buys thicker felt. In the DIVELUX store, any 3 hats are 15% off.
Which one should you buy?
- You sauna hot and long (190°F+, 15–20 minute rounds, banya): DIVELUX, for the thicker felt.
- You want the traditional bell shape: DIVELUX.
- You want a playful design or a novelty gift: Halsa.
- Your skin is sensitive to wool: Halsa's merino hat, or read our guide to wool sensitivity first.
- You want a light bucket hat for short gym sessions: either works; Halsa's is lighter.
Both are real wool, both fit up to 24 inches, and both have free US shipping and 30-day returns on their own stores, so neither is a risky purchase.
