The Best Material for Underwear │ The Ultimate Underwear Guide (2023)

Underwear is the foundation of any outfit, and it’s important to consider your comfort carefully.

Many people don’t pay much attention to what underwear they buy or perhaps wait until Christmas to be gifted some from family and friends.

But what is the best material for underwear? What should you buy? What should you give as a gift? Continue reading, as this guide will break down all the best materials for underwear for you or others in your life.

Choice of Underwear

Regardless of the material, you first need to decide what style of underwear best suits you. There are many kinds of underwear for both men and women, including briefs, boxers, boxer briefs, trunks, thongs, bikinis, and much more.

Do some research into what you think might be most comfortable for you, then move on to choosing the right material for you - taking skin sensitivity into account.

It’s also important to shop from reputable brands like Bawbags, who solely put their efforts into providing quality and comfortable underwear. They offer different underwear styles in men, women, and kids’ sizing.

By doing this, you set yourself up for a comfortable experience knowing that the brand you buy from cares about making quality products.


Cotton is a common choice for underwear because of its breathability, softness, and extreme comfort. However, it comes with pros and cons that are worth paying attention to:


  • Cotton is a natural and renewable resource, making it a great environmental choice.
  • It is a breathable material and absorbs moisture well, helping to keep you cool and dry where it’s needed.
  • Cotton is ultra-soft, making it very comfortable.
  • It is durable, making it last longer even after washes.


  • Cotton is prone to shrinking after washes.
  • Takes a long time to dry.
  • It can wrinkle easily.
  • It is susceptible to fading in colour.
  • Cotton doesn’t provide much stretch.

When it comes to cotton, it can be conventionally grown to use a lot of pesticides and other chemicals, so it is worthwhile looking out for organic cotton underwear when doing your shopping.

In summary, cotton is a great material choice for your underwear. If you are looking for a cosy feeling, pick a comfortable size, as it is not as stretchy as other materials.


Spandex, also known as elastane, is a synthetic elastic material often used in underwear for its stretch and additional support. Some of the pros and cons to paying attention to include the following:


  • Spandex provides great stretch and support, which can help provide a secure fit and flexibility for any growth.
  • It is lightweight and durable, allowing it to withstand multiple washes without losing shape or stretch.
  • It is a quick-drying material making it better for everyday wear and quick washes.
  • Activewear often uses spandex to provide a streamlined fit and better muscle compression.


  • Spandex tends to be less breathable than other materials like cotton, making it uncomfortable during Summer and hot weather. 
  • Due to it being synthetic, some people may find it irritating or have allergic reactions to it, causing rashes and skin irritation.
  • It is not biodegradable and can take a long time to break down.

Spandex is commonly mixed with cotton to provide the best of both worlds, helping to achieve a flexible and comfortable alternative.

Spandex is a good material choice if you prefer a streamlined fit with flexibility for growth.


Polyester is another synthetic fabric made from polymer resins, and it is best known for its durability and moisture-wicking capabilities. Similar to other materials, there are pros and cons:


  • Polyester is durable and can withstand many washes without losing any of its shape or quality.
  • Its moisture-wicking capabilities mean it helps to keep cool and dry during warm weather by pulling sweat away from the skin. 
  • It is quick to dry and deflects wrinkling very well.


  • It is not as soft as natural materials like cotton and can sometimes be abrasive against the skin, especially if allergic reactions occur.
  • Polyester can retain odours and bacteria, so it may require more frequent washing than other materials. 
  • It is not biodegradable, meaning it does not decompose well in the environment.

Like many materials, polyester is blended with cotton to balance comfort and performance.

Polyester-based underwear is great for those looking for underwear that is easy to care for and can withstand regular use.
