8 of the best organic underwear brands that are certified to be safe

I struggled with vaginal thrush throughout my teenage and young adult life, mostly because I didn’t know better. I chose style over comfort, going for lacy polyester underwear that didn’t breath and on hind-sight, was full of harmful chemicals.

It wasn’t until I started wearing organic cotton underwear that my embarrassing thrush issue went away. And no wonder, my groin could breath at last!

But why organic? Wouldn’t plain ole cotton do? Well, your groin area is the sweatiest, warmest part of your body. When you wear non-organic underwear, they are full of toxic chemicals. The warm humidity of your groin increases absorption of these chemicals by your sensitive skin.

With so many affordable organic underwear brands on the market, why put yourself at risk? Plus, wearing organic is better for the planet and for the people who are involved in making your clothes.

But beware. Some underwear brands might use organic fabric but dye their products with toxic dyes. Make sure your organic underwear is OEKO-TEX or GOTS-certified to contain no harmful chemicals.

These are my favorite organic underwear brands that are certified to be safe from toxins:

Majamas Earth

Check Majamas out on Amazon

Majamas Earth is a really cool Chicago-based fashion brand who make their eco-friendly clothing in the United States. They are one of the few sustainable companies around who also make clothing in bold, daring prints. It’s refreshing after all the neutrals associated with eco-friendliness.
