Interesting Facts About Wool & A Chance to Win a Merino Wool Face Mask


Before 2016, I didn’t realize how import natural fibers are to health and wellness. I never thought about toxins in synthetic fabrics. I knew nothing about petrochemicals in clothing.

After 2016, my life was turned upside down due to toxins in my airline uniform. That’s when I began focusing less on designer names and more on tags hidden somewhere inside an article of clothing. For me, fabric is more important than the designer. Whenever I find something made out of 100% cotton, silk, linen, or wool, it feels like I’ve discovered a pot of gold, even when I’m shopping for second hand clothing at Goodwill.

If you had told me a year ago I’d feel grateful to own a wool face mask, I would have laughed, but here we are at the end of 2020 in the middle of a pandemic and I love my Under Cover Sheep Merino wool face mask so much that I panic when I can’t find it and have to resort to wearing my old favorite mask. I won’t name the brand. I like my Under Cover Sheep Merino wool face mask so much I reached out to the company to see if they’d like to work with me, and they said YES!

I’m excited to announce I’m giving away Under Cover Sheep Merino wool face masks to a few lucky readers. To be eligible to win you must reside in the U.S. and leave a comment, any comment, preferably one about how much you love natural fibers or maybe a funny story about a mask or something you learned about yourself during the pandemic. Keep it positive and you’ll be entered to win. I’ll announce the winners names on my blog on Thursday, December 24, 2020 at 5 P.M. Pacific Time.

Now for a few interesting facts about Merino wool.

  • In contrast to synthetics, Merino wool can absorb moisture vapour which means less sweat on your body. Merino wool even absorbs the odour molecules from sweat, which are only released upon washing.
  • In contrast to synthetics, Merino wool is an active fibre that reacts to changes in body temperature. So it helps you stay warm when the weather is cold, and cool when the weather is hot.
  • Merino wool fibres are extremely fine, enabling them to bend far more than traditional, coarser wool fibres. This makes Merino wool feel soft and luxuriously gentle next to your skin.
  • Natural elasticity helps Merino wool garments stretch with you, yet return to their original shape. So Merino wool clothing is ideal to wear when exercising.
  • Most Merino wool garments can be machine-washed and tumble dried, providing a simple solution to the common question of ‘How to wash wool?’
  • Merino wool fibres have a natural protective outer layer that helps prevent stains from being absorbed. And because Merino wool tends not to generate static, it attracts less dust and lint.
  • When a wool fibre is disposed of, it will naturally decompose in soil in a matter of years, slowly releasing valuable nutrients back into the earth.
  • Merino wool is one of the most breathable fibres. Wool fibres can absorb large quantities of moisture vapour then move it away to evaporate into the air.

  1. Thank you, Heather, for sharing. I knew merino wool was finer than other wools, which makes it ideal for base-layer/undergarments. However, I did not know the science explaining why and how merino wool is so light, luxurious and exceptional. Keep up the great work that you do…!

    1. I live in Tucson, where for much of the year it is obviously very hot. Many masks make my face feel even hotter, so I’d love to try one of these Merino wool masks.

  2. I love how wool helps you stay warm when the weather is cold, and cool when the weather is hot. Would love try try these Merino wool masks!

  3. I’m a very healthy person, always have been but wearing some masks leave me feeling lethargic and with mild headaches. I’m looking for something to change that and if you stand by a wool mask then I’m in.

  4. Those look comfortable, and thank you for the reminder that wool doesn’t equal winter, since it’s something I tend to forget. Thank you for sharing such a great option since masks aren’t going anywhere

  5. Thank you so much for sharing this important information. I was a Flight Attendant for over 20 years, and had no idea about toxins in fabrics. I am a three time cancer survivor, and am always worried about breathing toxins in the air as well. Again, many thanks.

  6. I love wool, I was born on a farm in Ohio and I worked with sheep for a very long time. It brings a smile to my face to see wool to help stop the spread of COVID 19.

  7. I already bought 5 of the Under cover sheep when I read your last post about them. I gotta tell ya- they are so much better than any other face mask I’ve worn. And it doesn’t give me a headache after a long duty day at work like the other ones did. Mainly the disposable China made ones that I would wear. Thank so much for informing us about these mask.

  8. Wool’s inherent breathability and moisture-wicking properties help regulate my body temperature, keeping me cool in the summer and warm in the winter. My last TWA flight attendant uniforms were made of a year-round weight wool and proved this assertion to me during the four years we wore those uniforms.

    Wool naturally has a stretch to it. Even after a full day of wear, wool fabric easily snaps back into shape, despite continuous wear and cleaning. Years later, I’ve made two quilts with fabric from those Ralph Lauren-designed TWA uniforms!

    Two years ago while visiting on the east coast I found a treasure I’m sleeping under every night. While thrift store shopping, I was drawn to a wool blanket, found in its original wrapping. It was a beautiful lilac heather color and tightly woven. As a lifelong fine textile enthusiast, I wanted this blanket. The quality workpersonship was evident. At ten dollars, it was a bargain for this twin size blanket.

    At home I discovered the label which lead me to the website for Bartlett Yarns, a woolen mill operating in Harmony, Maine since 1821. All the wool is sourced in the USA too! Visit here:

    As I explored the Bartlett Yarns website, I discovered wool dryer balls. If clothes are not dried outside, these little wool balls absorb moisture from clothing in the dryer, maintaining a more humid environment, thus helping get rid of static cling. In addition to reducing static, they also reduce drying time and fluff clothes.

  9. If 2020 wasn’t enough, I discovered I had lung cancer after never smoking. It made me think about the toxins we breathe & what may have brought this on. In the thick of the pandemic I had the Stage 3 tumor removed successfully along with part of my lung. Yay me! Now more than ever, I’m looking for breathable, natural fabrics to use in the future.p & if Heather stands behind it, I know it’s good after her extensive research & experience.

  10. Thank you for this, Heather! I’ve used natural fiber clothes and products since 1980 after being diagnosed with MCS by Dr. Theron Randolph (sometimes called the father of clinical ecology/environmental medicine and an amazing human and kind doctor!). I’ve searched for safe masks but hadn’t seen wool ones— I’m so grateful to you! I’d love to try one of these merino masks.

    Also, my mother’s family name is Poole— I wonder if we’re connected in some way?!

  11. I didn’t even realize that masks made of wool were available but now that I am I’ll be checking out “Under Cover Sheep”. What a great idea, there are so many advantages to this. I esp like that it will absorb moisture. I only wear natural fibers because my body doesn’t tolerate synthetics. I am aware that wool makes a great natural insulator which is why we’ve decided to use wool insulation if we build a home. Kuddos to “Under Cover Sheep”.

  12. Thank you so much for all this wonderful information. Now I want to be more conscious about more organic fabrics and clothing.
