Sauna Hats Are Having a Moment - Here’s Why You’ll Want One (+ Let's Talk About Saunacore)

The Rise of the Sauna Hat

The sauna hat sits at the crossroads of tradition and reinvention, reflecting yet another way wherein sauna culture continues to adapt and evolve over time. While felt hats have long been part of Slavic Banya culture, in Finland they’re a more recent addition embraced for comfort, function, and - let’s be honest -style rather than purely cultural convention.

It’s a clever evolution, a modern nod to craft and care that fits naturally into today’s global sauna movement from Helsinki to the Kootenays in BC Canada.
​
Whimsical at first glance but far from a precious novelty, these hats offer both protection and smart design, proof that sauna culture continues to evolve with us.

Sauna Hats + the Rise of "Saunacore"

We can’t really talk about sauna hats right now without talking about Saunacore.

Saunacore isn't just about an aesthetic; it's visual proof of a cultural renaissance of "slowing down." Our friend + colleague, Linda Helisto calls on entrepreneurs in the wellness world to embrace "ease as the new hustle," and we couldn't agree more. The sauna hat sits right at the center of all this story, equal parts folk tradition and flex, a wool-felt wink to those in the know.

Across fashion feeds and wellness columns, sauna hats are suddenly everywhere - a woolen crown for a post-modern culture rediscovering what it even means (and feels like) to pause. Once a niche nod to Nordic and Slavic bathhouse traditions, the felt sauna hat has become a symbol of modern cool, where design and a little irony seem to coexist.

From Pamela Anderson’s quiet-luxury wellness rebrand to Seth Rogen’s viral Sauna Boss moment, and the Backstreet Boys sweating it out in Kazakhstan, the sauna hat is having its full-blown pop-culture moment. It’s showing up on photo sets, in influencer retreats (no, we've never been to one), and in those blurry 35mm selfies that make you wish you were there.
​
At its core, Saunacore is the cultural current that we're here for, a movement where functionality meets both consciousness and a little humor. Think less spa-day perfection, more real bodies + conscious living. We celebrate all of it - the slowness, the imperfect vulnerabilities, and the courage to laugh at ourselves, event when we're half-naked in public. 

If sauna is the original, ancient reset button, Saunacore is the remix, and a reminder that wellness doesn't (and shouldn't) need to be polished to feel good.

Why wear a sauna hat?

So let's get into the "booksmart-stuff" about sauna hats.

​When you step into the heat of sauna, your head and scalp warm faster than the rest of your body given the way the heat rises in the space. The head and scalp also heat up faster than the rest of the body because of their rich blood supply and direct exposure to hot air in the upper benches. A sauna hat functions as a thermal insulator, helping to slow down that rate of heat transfer and maintain a more even temperature distribution throughout the body.

Benefits of wearing a sauna hat include:
​

• It protects your hair and scalp from too much direct heat, helping prevent dryness and damage;
  
• ​It helps your body stay in better balance by keeping the temperature between your head and body more even; and
  
• It can make the whole sauna experience more comfortable so the heat feels relaxing instead of overwhelming.
  

​A well-made natural wool sauna hat helps regulate the body’s natural thermoregulatory response, improving comfort during prolonged sauna bathing.

Shape, Function + Craft of Design

The distinctive cone or mushroom shape ("Gnomecore" enters the chat) of a sauna hat isn’t just an aesthetic thing for the 'gram; It’s part of the hat’s natural engineering. For example, the air pocket above the scalp creates a natural insulating layer, while the flared brim shields ears and forehead. The denser the felt and the more stable the air gap, the better the insulation.
​

• Cone shape → lets hot air rise away from your head.
• Wide brim → protects sensitive areas from direct heat.
• Dense wool felt → maintains breathability while blocking radiant heat.

Given our Finnish roots and partnerships, we’ve begun collaborating directly with Finnish designers and producers who carry forward the country’s legacy of purposeful design. In Finland, form always follows function, and the beauty lies in how seamlessly the two coexist.

Every curve, seam, and material choice in a quality wool sauna hat is intentional by true craftsfolk wherein hats are crafted to maintain thermal balance, comfort, and longevity, while embodying quiet precision, local skill + minimalism.

From Banya Roots to Nordic + Global Reinventions

The earliest sauna hats originated in Slavic and Baltic steam-bathing traditions, where bathers wore thick felt hats to endure the intense humidity of banyas. These hats protected the head, allowed for longer sessions, and quickly became part of the ritual.

In Finland, the sauna hat entered the scene later. Finnish artisans embraced the idea, crafting hats from locally sourced wool, shaped with minimalist precision and ecological care.

Now, sauna hats, like our handcrafted Keidas Sauna Hat, represent a fusion of heritage and innovation: inspired by neighboring traditions, refined through Nordic craftsmanship, and aligned with the modern sauna lifestyle.

Sustainability Woven In

We only work with producers who share our commitment to authentic materials, ethical production, and enduring design. Our first batch of sauna hats are handcrafted in Finland by a small, family-run textile studio that continues the country’s long tradition of wool craftsmanship.

Their process begins with locally sourced wool, washed and felted using minimal water and biodegradable soaps. These are timeless materials shaped with care, without synthetics nor mass production. 

Handcrafted from wool, a well-made + ethical sauna sauna hat will carry the spirit of slow design that is intentional, enduring, and rooted in respect for nature and craft. Every detail, from felt density to stitching, shows a deep understanding of wool as a living, renewable fiber.

• Natural fibers: 100 % Finnish wool that is renewable, biodegradable, and naturally heat-resistant.
• Ethical production: Each hat is made by hand in small batches, ensuring fair working conditions and traceable sourcing.
• Circular design: Built to last, designed to age beautifully, and capable of returning to Earth at end of life.

​Each hat embodies the same values as sauna itself including simplicity, sustainability, and respect for nature’s rhythm.

 Caring for your (Natural Wool) Sauna Hat

• Air dry after each use; never store it damp. (We always leave our sauna hats directly on our personal sauna bench after feeding the kiuas one last time which dries it out perfectly).
• Gently spot-clean with cool water if needed.
• Avoid harsh soaps or machine washing — natural wool’s lanolin is self-cleaning.
• Store in a breathable bag or on an open shelf away from sunlight.

With a little care, your natural wool sauna hat will last for years, carrying the scent of freshly-cut firewood and the memory of good heat.

Final Thoughts

The sauna hat is a paradox in the best way, where folk tradition meets a little flex. It carries equal parts heritage and humor, embodying everything sauna stands for: humility, heat, and the understanding that we all meet as equals in the steam.

If sauna is the ritual, the hat and that Saunacore spirit are the reminder to slow down, laugh often, and not take wellness, or yourself, too seriously.
