The 5 Best Organic Underwear

Whether you’re dealing with sensitive skin or just prefer ethical brands, the best organic underwear provide comfort and peace of mind. In this roundup, you'll find a wide selection of organic undies. Whatever cut you prefer, there’s a healthy underwear pick to meet your needs.

The two common materials used for organic underwear are cotton and bamboo. Since cotton’s a soft, natural, and breathable fiber, it's one of the best fabrics for sensitive skin, but since it's non-wicking, bamboo undies are better for exercising and hotter days.

Organic undies come in a variety of cuts from bikinis to briefs to hipsters to thongs. However, it's important to understand what labels and certifications guarantee your pick is truly organic.

Important Certifications

  • Ecocert: Ecocert is an organic certification organization that conducts inspections in over 80 countries.
  • GOTS-Certified: The Global Organic Textile Standard (GOTS) is the worldwide leading textile processing standard for organic fibers.
  • Organic Content 100 Standard-Certified: The Organic Content Standard (OCS) applies to any non-food product containing 95-100% organic material, tracking raw materials from their source to the final product.
  • STANDARD 100 by OEKO-TEX: STANDARD 100 by OEKO-TEX doesn't guarantee a product is organic, but it's one of the best-known labels for textiles tested for 100 potentially harmful substances.

Pact and Boody are highly respected, ethical organic brands, so several picks below are from those companies. Take a look at the best organic underwear available on Amazon.

1. The Best Organic Bikini

Boody Body's classic bikini organic underwear contains 80% rayon made from organic bamboo, 13% nylon, and 7% spandex.

4. The Best Organic Hipster

What fans are saying: “Hands down the best underwear I've ever owned. I have very sensitive skin and always buy cotton underwear, and sometimes even 100% cotton irritates my skin. I later discovered that this is because some companies ‘treat’ their underwear in formaldehyde. [...] I am slowly throwing away all my old pairs and replacing them with PACT. I would recommend these to anyone!”

  • Available Sizes: X-Small - X-Large
  • Available Colors: Black, Charcoal Heather/Redwood, Teal/Mist, and Plum/Lilac.

5. The Best Organic Brief With Plus Size Options

  • Cut: Briefs

These briefs by Hesta are made from 95% organic cotton and 5% spandex. Since briefs provide ample back and front coverage, they’re one of the most comfortable cuts around; but these still offer a little cheekiness, if that appeals to you. Additionally, Hesta is a GOTS-certified and Organic Content 100 Standard-certified company.

They’re even available in plus sizes and boast 4.1 stars and hundreds of reviews.

What fans are saying: “I am always nervous ordering clothes online, but I need not have worried. I love these! They are cut perfectly. (I have a rounded bottom, so it's nice to have panties that fit!) The cotton is so soft I enjoy wearing them, and they are so comfortable. They are also made very well. They hold up in the wash, and still look pretty and new. I recommend them highly.”

  • Available Sizes: XS - 4XL
  • Available Colors: White, Black, and Tan.
