So, let’s have a look at the choices of the best fabric for men’s underwear. From organic cotton to bamboo, wool and eucalyptus fibers to recycled polyester, they are all comfortable and breathable.

Organic Cotton

Cotton is the most popular underwear material because it is breathable and absorbent. But conventional cotton is one of the dirtiest crops, grown using chemicals and genetically modified seeds.

So it is very important to choose organic cotton.

Organic cotton is one of the best material men underwear can be made from

Organic cotton is grown from seeds and plants that have not been genetically modified. No harmful and toxic chemicals are used during the growing and production processes.

Organic cotton is softer than conventionally grown cotton. Because of the absence of harmful chemicals, it is far better for your skin and health, and perfect for hypoallergenic underwear for men.

Cotton is soft, hypoallergenic, breathable, absorbs moisture and sweat. It keeps you ventilated and air circulating to keep you comfortable. The sweat and moisture wicking qualities, make organic cotton a perfect choice for everyday wear.

The biggest benefit of organic cotton is that you are not exposing the delicate parts of your body to any chemicals. Read more about the production and benefits of organic cotton in this post on What is organic cotton clothing?

Although cotton is most common and perfect for everyday wear, it’s not the best for heavy workouts. As cotton is absorbent, it will absorb all your sweat. This is great, but it will make your undies heavy and uncomfortable.


Bamboo has strong anti-bacterial and anti fungal properties, to help to keep your body healthy and hygienic. Moisture wicking, prevents rashes and itching.

Bamboo is lighter and softer than cotton. Bamboo is perfect for hypoallergenic underwear for menThe anti-bacterial properties of bamboo sets it apart if you are looking for hypoallergenic underwear for men.

There are many advantages and benefits of choosing bamboo for your clothing, bedding and other household products.

  • Bamboo is naturally hypoallergenic and the fabric is as soft as silk. The fibers undergo no chemical treatments so they are naturally round and smooth. This hypoallergenic quality means that it doesn’t cause allergic reactions. So it is kind to sensitive skin and fabulous for allergy sufferers.
  • Bamboo is naturally anti-bacterial and anti-fungal. This inherent quality of bamboo allows it to grow naturally in the wild without having to treat the bamboo crop with pesticides, fertilizers or chemicals.
  • Bamboo is extremely breathable. The hollow structure of a bamboo fiber promotes moisture absorption and evaporation making it more breathable than cotton.
  • Bamboo is highly sweat absorbent and pulls moisture away from the skin for evaporation. It therefore keeps you dry and let the body breathe naturally.
  • Bamboo is powerfully insulating. The hollow fiber has unusual breathing capabilities, which keeps you cooler in the summer and warmer in the winter.
  • Bamboo products are 100% biodegradable making it the most renewable resource on the planet. It is naturally grown, making it kind to the environment.

Merino wool

Merino wool is breathable, temperature regulating and moisture wicking. Fibers are very soft and smooth with no itchiness whatsoever.

Merino wool is 20% the diameter of human hair, so it is super fine. It is very absorbent, so not ideal for hot summer’s day, but perfect for cold weather.

If you are allergic to lanolin, then organic cotton or bamboo might be better for you.

Tencel Lyocell

Lyocell has become the generic name for cellulose fiber, obtained from trees. It is made with a closed loop organic solvent-spinning process. Lyocell is known in the USA under the brand name Tencel.

Men’s eco friendly underwear will be made from eco friendly eucalyptus wood pulp. It doesn’t give the best support, but is good for sleeping.

Recycled Polyester and Nylon

Although nylon and polyester are used for underwear, it is NOT an eco friendly fabric, unless recycled plastic is used.

Polyester and nylon can trap heat and moisture, which is not ideal for everyday wear. Also, the chemicals could wreak havoc with the sensitive skin of your private parts.

  • Polyester is thin and breathable, but doesn’t have the moisture wicking advantages of natural fibers. Because it doesn’t absorb moisture, avoid wearing during warm months.
  • Nylon: Microfibers of nylon will keep you dry during a workout when comfort is the key. Nylon is good for the gym, but if you care about the environment, you will avoid it, unless it is recycled.
  • Mesh fabric is very popular for sportswear and can be made from polyester, nylon or other structured material. It does have a huge negative impact on the environment.

Recycling converts waste materials into new products and materials. Natural resources are saved, as well as energy. This is because the recycling process reduces the amount of energy input that is required.

Recycling reduces ocean plastic waste, it prevents products from ending up in landfill, and has a much smaller carbon footprint, than virgin materials.

So if you buy underwear for gym or workouts, make sure it is made from recycled materials. PrAna and Organic Basics fit the bit for that and you will find them below. .


Moisture wicking properties of hemp make underwear breathable and comfortable. Also, resistant to mold and UV light and has very good color retention.

Hemp is anti-bacterial, anti-microbial and has anti-odor properties. It is not that common to find hemp underwear yet.


Silk is incredibly breathable and light, but not widely used for an eco friendly underwear men range. The reason for this is that the fabric is delicate, and thus wears out quickly.

Silk is soft, smooth and absorbent and best for special romantic evenings.

  1. Hello, Line’

    Thank you for writing such a fascinating and informative article.
    I agree with you; I like to use eco-friendly materials like cotton, bamboo, or viscose whenever possible.
    The majority of my wardrobe is made up of these types of fabrics. 

    Also, as more options and real knowledge about eco-friendly clothing options become available, an increasing number of individuals are able to select the best clothing choices for themselves. I’ll be back to your Organics Basics to make further shopping.


  2. Thanks for sharing this article. The one new thing I learnt today is finding out from this piece that under wears are produced from bambo.  I am also happy to know about eco friendly underwear. For me I would always go for natural ones. Some synthetic-made underwears cause skin irritation either because they are too silky or because they are non absorbent. 

    • Eco friendly underwear is made from a variety of fabrics, including bamboo, organic cotton and responsible wool. Synthetic fibers can cause skin irritations because of the chemicals used. Natural fibers are often best for underwear to wear all day long. 

  3. I really like this eco friendly underwear, seems to be a really good idea to wear this eco friendly underwear specially because all the healthy fabric they used. I can use this type of underwear for me feel a little bit tight. Do you have any recommendation for boxer underwear that is eco friendly like this one’s? Let me know.

    Thank for this sharing this great post very well explained.

    God Bless You 

    • These brands all produce eco friendly boxer underwear. If your underwear feels too tight, I suggest you order a larger size that won’t be too tight. I hope it helps. 

  4. Thanks for sharing this review on the 5 best men’s underwear brands. I have always supported  eco friendly products as a believer of saving the environment. I am a strong believer in buying underwear for men made from organic cotton as it absorbs sweat very well and are chemical free and would not cause irritation to skin is a plus. My nephew bought some bamboo underwear recently and he said it feels comfortable. So I know that our are onto something good. 

    • Underwear that can absorb sweat is the best as you do not want sweat or moisture sitting on your skin. Bamboo underwear is awesome, as is organic cotton. It wicks away any sweat to make you feel comfortable under all circumstances. Underwear with wool is perfect if you are heading towards colder climates and underwear for working out, has different prerequisites. eco friendly underwear has something for everybody.

  5. It’s so important to have comfy underwear and having two boys and a husband, I’m often shopping for boxer shorts (the fitted types that you show in your article) as these suit them all and fit well.

    I never knew how many different types of brands there were or the added benefit of choosing ones with certain material.

    My youngest hates anything that scratches and is always cutting out the labels from most of his clothes and his underwear is no exception!

    I love the fact that you have listed the different types of materials that are available and never really thought of allergies and skin sensitivity before for underwear so your article has been very informative and given me some great tips on what to buy.

    Thanks for sharing.

    • My 2 boys also hate anything that scratches and would cut labels out of everything. Today the one always wears bamboo, whereas the younger one swears by organic cotton. Awesome that there are so many choices of eco friendly materials to suit all individual preferences. 

  6. Have always bought 100% cotton underwear for my husband and now after reading your review am going to have to check out Bamboo material. There are more benefits to Bamboo than cotton especially the breathable feature, as the husband comes about not being comfortable. I will be sharing your review with my social media followers. 

    • Bamboo is indeed a very comfortable fabric to wear and my sons love it. I am sure your husband will find it comfortable as well. All the best, Liné

  7. I really enjoyed this post. It has made me want to replace all my underwear with organic products. I particularly liked the Organic Basics range. I wear tank bras in bed, and theirs look so comfy! It is only recently in the grand scheme of things that people are starting to think about eco-friendly clothing. It is a pity that we ever started making clothes from man-made fibers using lots of chemicals in the first place. 

    I think most of us have a wardrobe full of synthetically made clothes, and it would take time to replace everything, but it is certainly possible if every time we need a new item, we buy an environmentally friendly version.

    Thanks for a great article and the easy links for finding these innovative products. I was able to click on them to find women’s products as well as look for items for my husband.  For me, comfort is one of the main considerations when it comes to underwear, and these products all look so snug and comfy. 

    • I agree with you that the way to start an eco friendly wardrobe, is to buy an eco conscious version when you need to replace anything. I am sure you and your husband will enjoy wearing organic underwear. All the best, Liné

  8. My son-in-law has MS, so he and my daughter are very careful what they put in and on their bodies. I will have to tell them about these underwear. I love that they are made from an eco-friendly cotton and bamboo and are safe for sensitive skin. It’s an added bonus that these underwear absorb sweat so well. 

    • Hi there, the best material men underwear can be made from, are organic and natural fibers. They are far safer and healthier than petroleum based synthetics. I hope your son-in-law and daughter will find the selection of hypoallergenic underwear for men helpful. All the best, Liné

  9. My wife will love looking at this information. She usually does the shopping and when the time comes for me to buy underwear I usually say “Just get whatever looks good.”

    Now I know what to tell her. I think the bamboo or cotton would be the best for me. Sometimes I have to change my underwear three times during the day because it just gets too moist. I know from prior experience that can lead to a terrible rash so I am now quite tuned in to keeping things dry.

    I have a bamboo pillow and just love it. I will try these bamboo underwear.

    Thank you for this information. I would not normally look up something like this but it can be very important to ones hygiene.


    • Hi Myron, it sounds to me as if you need to change the fabric of your underwear and have the best material men underwear can be made from. For daily wear, I would recommend organic cotton or bamboo, or if you live in a cold climate, then the wool and eucalyptus blend from Allbirds. 

      If you like bamboo, then I recommend the bamboo underwear from Thought. I hope this helps you, Liné 

  10. This is especially helpful for someone who is buying underwear for someone else and doesn’t wear men’s underwear themselves. Shopping for men’s underwear can already be pretty challenging under normal circumstances, but it’s even more so when you want to support an eco-friendly brand that will be good for the planet. Thanks for these options to consider. The bamboo options seem great!

    • Bamboo is indeed a great choice for men’s eco friendly underwear, specially if you are looking for hypoallergenic underwear for men. The best material men underwear can be made from, are organic and natural fibers. All the best, Liné

  11. Hey there,

    Thank you for this great article and introducing me to the 5 best men’s eco friendly underwear brands. I honestly would never know where to look if it were not for this post. I fortunately do not have sensitive skin but I am bog on saving the environment. The Allbirds and Organic basics sound like good brands and might give them a try. I regularly change my underwear and I am a boxer briefs guy.

    Regards, Lawrence

    • Hi Lawrence, these brands all produce awesome men’s eco friendly underwear and I am sure your body and the environment will benefit from supporting these brands. All the best, Liné

  12. Wow, what a great website and so comprehensive!  I love the footwear section since I have a thing about shoes.  Allbirds wins!  I had no idea.  Thanks for sharing this information.

    I also loved reading about the sewing machine reviews, the handicrafts, and the recycling sections.  Of course, the baby and kids section had me right away, being a new grandma.  I will send your website link to my daughter as she is all about sustainability and protecting our environment.  You have a gold mine here.  Beautiful website!

    I applaud you for making a difference for our environment by providing excellent resources for sustainability.  You have outdone yourself.

    Best of luck to you,


  13. Thanks for this article! Although I am not male, I can most definitely get behind comfortable underwear! Despite the obvious differences, I can see relatable material to both men and women underwear.

    Bamboo is a very popular material, and my bed sheets are entirely made of it. The antifungal and anti bacteria aspect really sets the win for me. What is the most popular material on the market right now? I’d be curious to know.

    I look forward to hearing from you!


    • The anti bacterial and anti fungal properties of bamboo indeed sets it apart and makes it perfect for hypoallergenic underwear for men and women. Cotton is very popular for underwear, but it is mostly conventional cotton, not organic cotton. 

      The material that is the most popular, is not always the best for you or the planet. Synthetic fabrics are cheap to produce, but the chemicals are harmful and toxic, so bad for your health and the environment. 

      I would rather wear clothing that is not harming me, or the planet. 

  14. I think it is great that they are making eco friendly underwear. My teenage boys lovs to wear those. They say it feels more Comfortable. It is great for climate as these will destruct themselves pretty fast if they are 100% Ecofriendly. I think the Bamboo one is a great choice.

    • Hi Hilde, bamboo is a great choice for underwear and my boys love it, as well as organic cotton. These are the best material men underwear can be made from, specially if you are looking for hypoallergenic underwear for men. Liné

  15. Thanks for a great article on eco friendly men’s underwear!  I enjoyed reading this for both its coverage of the health benefits this type of underwear can bring and also the review of top five brands retailing  these products.

    Natural fibers and organic cottons make sense in a world that is suffering from near ecological collapse.  When these items are sourced under Fair Trade agreements there are a lot of winners all round. I would certainly buy these for the men in my life!

    • Organic cotton and natural fibers are just so much better for your health, as well as for the environment. So it is indeed great to get men’s eco friendly underwear. The men in my life are benefiting from wearing these.

  16. Although there’s a lot of concern about dangerous chemicals in our food, and organic food is becoming increasingly popular as a result, there isn’t enough concern about the fabrics we use having been treated with unhealthy chemicals. It’s worth considering buying garments made out of organic cotton as well as the other healthy fabrics listed. Although hemp garments aren’t that widespread, I’ve heard that hemp is an unusually durable fabric.

    • Hemp is indeed a very eco friendly and sustainable fabric, although it is not that common to find men’s eco friendly underwear made from hemp. Chemical in fabrics can cause skin rashes and allergies, so it is important to wear hypoallergenic for men if you suffer from eczema, or other allergies.
