Merino wool is a game-changer for people with sensitive or allergy-prone skin. Unlike traditional wool, its ultra-fine fibers (15–19 microns) are soft and gentle, reducing irritation. Studies show superfine merino wool can help manage eczema and other skin conditions, thanks to its moisture-wicking and breathable properties. It absorbs up to 30% of its weight in moisture without feeling damp, keeping skin dry and comfortable. Plus, it's low in lanolin, making allergic reactions rare.
Key Benefits:
- Soft Texture: Fine fibers bend easily, preventing itchiness.
- Moisture Management: Wicks sweat effectively, keeping skin dry.
- Hypoallergenic: Rarely triggers allergic reactions.
- Therapeutic for Eczema: Shown to reduce symptoms like redness and dryness.
For activities like sauna use, merino wool excels due to its ability to handle heat and humidity. Products like Schvitzin's handcrafted sauna hats ($120.00) offer comfort and protection, showcasing merino wool's unique skin-friendly qualities.
What You Need to Know About Wool Allergies
Common Myths About Wool Allergies
Despite its reputation, wool is rarely the cause of true allergic reactions. In fact, research spanning over a century has found no evidence that wool itself is an allergen. Interestingly, consumer surveys show that while 43% of people avoid wool due to its perceived itchiness, only 9% cite self-diagnosed wool allergies as the reason.
What many assume to be a wool allergy is often just skin irritation caused by coarse fibers. This irritation isn't specific to wool - it can happen with any coarse material, whether it's synthetic or natural. When genuine wool allergies do occur, they are usually linked to lanolin, the natural oil in wool, rather than the fibers themselves. Even then, lanolin allergies are uncommon; a study of over 24,000 individuals identified as high-risk found that only 1.7% had reactions to lanolin.
The distinction between sensitivity and allergy is key. Wool sensitivity results in surface-level irritation that disappears once the irritant is removed. A wool allergy, on the other hand, is a genetic condition where the body treats wool as a harmful invader, triggering a specific immune response.
Angus Ireland from The Woolmark Company highlights the need to address these misconceptions:
"Research is showing superfine wool base-layer garments to be beneficial to people with sensitive skin, such as eczema sufferers, so it's important to address misperceptions that wool is an allergen or that all wool is itchy when worn directly against the skin"
Clearing up these myths paves the way for understanding why merino wool stands out as a skin-friendly option.
What Makes Merino Wool Different
The difference between traditional wool and merino wool lies in the fiber's diameter. Traditional wool fibers often exceed 25 microns, which can create a scratchy sensation. In contrast, merino wool fibers measure between 15 and 19 microns - so fine that they're softer than cotton or even silk. Studies show that irritation typically occurs with fibers measuring 30–32 microns or larger. Because merino wool falls well below this range, it’s far less likely to cause discomfort. Additionally, merino wool features smoother surface textures, further reducing skin irritation.
Medical researcher Michaela Zallmann and her team emphasize this in their findings:
"Current evidence does not suggest that wool-fibre is a cutaneous allergen. Furthermore, contact allergy from lanolin, chromium and formaldehyde is highly unlikely with modern wool garments. Cutaneous irritation from wool relates to high fibre diameters (≥ 30–32 µm). Superfine and ultrafine Merino wool do not activate sufficient c-fibres to cause itch, are well tolerated and may benefit eczema management"
The quality of superfine merino wool is so distinct that it is officially recognized as asthma and allergy friendly. Allergy Standards Limited supports this, noting:
"There is a growing body of evidence to suggest that high quality, fine Merino wool is non-irritant and of low risk to those with sensitive skin"
For individuals with sensitive skin, especially those who enjoy activities like saunas, merino wool offers a perfect solution. Its fine fibers and smooth texture create a comfortable, non-irritating barrier, even in the high heat and humidity of sauna environments.
Wool is good for the skin
Why Merino Wool Works Well for Sensitive Skin
Merino wool stands out as a fantastic option for those with sensitive skin, thanks to its unique properties that ensure comfort and minimize irritation. Let’s take a closer look at how it achieves this.
Ultra-Fine Fibers for a Softer Feel
One of the reasons merino wool is so gentle on sensitive skin is its ultra-fine fibers. These fibers are incredibly soft and flexible, bending easily on contact to reduce irritation. Unlike coarser materials like acrylic or nylon, which can feel prickly, merino wool fibers have smaller and more numerous scales. This design reduces friction points and enhances comfort - some even compare its softness to cashmere. Research supports this, showing that the sensation of prickle increases as fiber diameter grows. Beyond its softness, merino wool also excels in managing moisture, a key factor in skin comfort.
Moisture Control and Breathability
Merino wool is exceptional at keeping skin dry and comfortable. Its fibers absorb moisture while allowing air to circulate, creating a breathable environment that prevents dampness - a common cause of irritation. Whether you're sweating during a workout or dealing with humid conditions, merino wool wicks sweat away from the skin and releases it into the air. This moisture management not only keeps the skin dry but also helps regulate body temperature, reducing discomfort and irritation. Combined with its natural breathability, this makes merino wool a great choice for people with sensitive skin.
Minimal Risk of Allergic Reactions
Merino wool also has a low likelihood of triggering allergic reactions. This is partly because it contains very little lanolin, the natural oil sometimes associated with skin sensitivities. Even when lanolin allergies occur, they are rare - one review of over 24,000 high-risk individuals found that only 1.7% showed a reaction to lanolin. Additionally, merino wool's natural antimicrobial properties help prevent bacteria buildup on the fabric, reducing the chances of skin breakouts or rashes. Interestingly, medical studies have found that superfine merino wool garments (with fibers ≤17.5 microns) may even offer therapeutic benefits for conditions like eczema.
With its soft fibers, excellent moisture control, and low allergen risk, merino wool is an excellent choice for anyone with sensitive skin, offering both comfort and performance in various conditions.

Research and Real-World Proof That Merino Wool Works
Scientific studies and practical applications highlight how superfine merino wool can help alleviate sensitive skin issues.
Medical Studies on Merino Wool
Research from respected institutions confirms that merino wool is not only safe for sensitive skin but may also improve certain skin conditions. For instance, a study led by Associate Professor John Su at the Murdoch Children's Research Institute in Melbourne, published in the British Journal of Dermatology, found that superfine merino wool clothing reduced the severity of mild to moderate atopic dermatitis in children compared to cotton clothing. Similarly, research headed by Dr. Lynda Spelman at the Queensland Institute of Dermatology in Brisbane, published in the Journal of Scientific & Technical Research, demonstrated that wearing superfine merino wool directly against the skin helped ease eczema symptoms in both adolescents and adults. Another study by Professor Joe Fowler from the Division of Dermatology at the University of Louisville, published in Dermatitis, revealed that fine-diameter merino wool not only reduced the severity of atopic dermatitis but also improved patients' overall quality of life.
These findings are especially relevant given that eczema affects up to 28% of children. Furthermore, the Asthma and Allergy Foundation of America has recognized merino wool as asthma and allergy-friendly. A review of a century’s worth of research also found no evidence suggesting wool is an allergen. These insights help explain why merino wool is so effective at providing comfort, even in high-heat environments.

How to Care for Merino Wool Products
Taking proper care of merino wool helps maintain its gentle, skin-friendly properties. It's surprisingly easy to clean and keep in great condition.
How to Clean Merino Wool Properly
Always start by checking the care label for specific instructions.
For hand washing, use cool water and a detergent made specifically for wool, or a mild soap with a neutral pH. Let the item soak for 3–5 minutes, then gently move it around in the water - avoid twisting or wringing it out.
If you prefer machine washing, select the wool or delicate cycle and use cool or warm water. Turn garments inside out, wash similar colors together, and use a low spin setting to protect the fibers. Remove items promptly after the cycle ends to avoid wrinkles.
Skip fabric softeners and bleach - these can coat the fibers, reducing merino wool’s natural moisture-wicking abilities, which are key to keeping the fabric gentle on your skin.
For stains, act fast. Rinse the area with cold water and dab it gently with a soft cloth. Avoid rubbing, as this can push the stain deeper into the fibers.
When it comes to drying, always lay your merino wool flat on a clean towel or drying rack. To remove excess water, you can roll the item in a towel before laying it flat. Keep it away from direct sunlight and heat sources like radiators or dryers, as these can damage the fabric. Never hang wet merino wool - it can stretch and lose its shape due to the weight of the water.
"Merino wool is like the self-cleaning oven of the fabric world. Its fibres have a natural ability to repel dirt and odours, thanks to the unique structure and lanolin content, which is a type of wool grease with antimicrobial properties." – Sheep Inc
Thanks to this natural self-cleaning quality, merino wool doesn’t need frequent washing, which helps preserve its hypoallergenic nature over time.
Proper cleaning is just the first step - storing your merino wool correctly is just as important.
Making Your Merino Wool Last Longer
Storing merino wool the right way helps it stay in top condition and maintain its soft, skin-friendly feel. Always ensure items are clean and completely dry before putting them away.
- Fold knitted items to prevent stretching, and hang woven shirts on padded hangers to maintain their shape.
- Opt for breathable storage like cotton garment bags instead of plastic, which can trap moisture and lead to mildew. Calico garment bags offer an extra layer of protection.
- Use natural moth repellents, such as cedarwood blocks, lavender sachets, or whole cloves, to keep pests away without using harsh chemicals.
Store your merino wool in a cool, dry place, away from direct sunlight, attics, or damp basements. Fluctuating temperatures and humidity can damage the fibers over time.
To keep pests at bay, air out stored items periodically and vacuum storage areas. Since heat can permanently shrink merino wool, always wash with cool water and dry flat to ensure your garments remain soft and well-fitting for years.
