Recently opened up your panty drawer to find a pile of worn-out and washed-out undies that need to be replaced?

You’ve positively worn your briefs to death – and we applaud you for that!

But now seems like the perfect time to restock your inventory of intimates with the help of the best organic cotton underwear brands.

Let’s face it. Nothing can beat organic cotton’s breathability, durability, and comfort. So it’s safe to say that it is definitely worth the investment!

It’s important to understand that not all underwear are made the same. 

We want our flirty thongs and seamless briefs to meet our own aesthetic demands, however, sustainability and durability should also be non-negotiable. 

That’s exactly where investment-worthy organic cotton underwear made in USA and Europe comes in! 

Free from most chemicals, fertilizers, and pesticides, this natural material uses less water, preserves soil quality, and limits soil erosion. On top of that, it’s softer and safer for the skin –especially when it’s destined for the most sensitive skin regions. Moreover, our curated list of the best organic cotton underwear brands women absolutely swear by includes only ethically-made styles.

So whether you prefer 100 percent cotton underwear that leans towards the simplistic vibe that jives well with your personal sensibilities or bralettes with a bit of personality, there is something special for you, ahead. 

Is 100% cotton underwear the best?

When it comes to breathability, comfort, and durability, organic cotton underwear is by far the best choice. It’s no secret that synthetic materials help all kinds of infections thrive. Organic cotton, however, can absorb any extra moisture which is a great way to significantly reduce your chances of developing an infection. 

But aside from being moisture-wicking, the best 100 percent cotton underwear can also remove the build-up of heat from your vagina to prevent odor. Also, the farming process of organic cotton uses less energy, releases fewer greenhouse gases, and due to the lack of chemicals, it is ideal for super sensitive skin –even babies’.

Which type of underwear is best for women's health?

When it comes to underwear, natural fabrics like cotton and hemp are the best type for women’s health. In fact, organic cotton can prevent UTIs. That’s one of the reasons why athletes opt for naturally smooth and stretchy materials (like the best 100 cotton underwear below) that are quick-drying and will wick away sweat. 

Is organic cotton underwear worth the cost?

Granted, the best organic cotton underwear brands may seem a bit expensive at first compared to the $5 polyester options, however, they are totally worth it. 

By choosing organic fibers, you help limit your body’s exposure to harmful chemicals found in man-made textiles like polyester or even regular cotton (which requires GMOs and pesticides to grow). 

For people with skin sensitivities, in particular, organic cotton underwear is the number one choice as it does not have any chemicals and successfully wicks away moisture. Also, let’s not forget that sustainable underwear brands thrive on creating intimates in safe and ethical factories where workers are getting paid fairly whereas. This, combined with the many certifications they have, is something that can drive up the price of organic cotton undies.
