I’ve tried a bunch of nontoxic underwear over the last five years, and I’m sharing my absolute faves. The best underwear is made with 100% GOTS certified organic fabrics and without harmful chemicals like PFAS, formaldehyde, microplastics and petrochemicals. It should be comfortable, breathable and safe for sensitive skin.

Typical underwear can contain BPA, PFAS, formaldehyde and heavy metals from dyes and chemical finishes. There was a recent study done that showed that underwear made from synthetic fibers like polyester and polyamide had high levels of BPA.

Since we’re wearing panties ALL day and night, 365 days a year (I don’t even wear my bras that long!), and it directly touches the most intimate and absorbent area of our body, it’s important to make the switch. Plus once you experience natural fiber undies, I doubt you’ll want to go back to the icky plastic-y feeling of synthetic.

Types of Non Toxic Underwear

Material: Organic cotton (the healthiest!), hemp, linen, bamboo, Tencel lyocell, merino wool, modal

• Organic cotton: safest and healthiest option, especially GOTS certified
• Modal: made from the pulp of beech trees and is considered semi-synthetic
• Bamboo: super soft fabric that’s safe when made in a closed loop process
• Tencel lyocell: made from eucalyptus trees and safe when made in a closed loop process.
• Merino wool: soft and moisture wicking but watch out for brands that use a chemical coating called “superwash”

Style: Bikini, Thong, Brief, Boy Short, Hipster, Boxers, Maternity

I tried Kent Organic Supima Cotton Bikini (Andrea’s fave!)

Kent’s 100% Organic Supima Cotton Bikini underwear is my top pick and stood out from the crowd for me. This is hands down THE most breathable and soft cotton panty my booty has experienced. It also happens to be on the pricier end, but if you want the best of the best, Kent beats all the other brands hands down. These are truly non-toxic and made of 100% natural fibers without any synthetics, petrochemicals, microplastics, and BPA. And yet it performs like traditional underwear and feels even better. They’re soft, durable and do not feel flimsy at all. The medium size is a true medium on the generous side for me. I continuously update with new items I test and it amazes me how far all natural underwear has come.

I tried Organic Basics Flex Hipster

Organic Basics makes one of the most affordable certified organic underwear on the market. They’re made of 91% GOTS organic cotton and feel soft and stretchy. These do feel a little bit more durable than Pact’s so between the two I would go for Organic Basics. The medium feels true to size for me but I wouldn’t mind a little more room. These aren’t the most luxurious panties but I feel they’re a solid budget-friendly option in the organic underwear space. I try to always go for black underwear so it lasts as long as possible but they have a wide variety of 10 colors.

Price: $17
Material: Body: 91% Organic Cotton, 9% Elastane – Gusset: 95% Organic Cotton, 5% Elastan
Fit: True to size

I tried Q for Quinn Classic Brief

I first tried Q for Quinn Classic Brief three years ago when I was on the hunt for 100% organic underwear, and they have held up well. This is a really substantial panty, is how I would put it. They’re hefty and run warm for me, so I only gravitate towards this during the colder months. During the warmer months I definitely want to wear something more breathable. Q for Quinn is one of the few brands that makes truly 100% organic cotton underwear without any synthetic materials. They actually offer both 95% organic cotton and 100% organic cotton options in either undyed or azo-free plant dyes to suit everyone’s needs. There’s also a ton of styles to choose from, including boxers and maternity. I would just recommend washing the 100% organic cotton ones in a mesh bag on cold or by hand to protect the fabric from pilling. Because the fibers are all natural and untreated with chemical finishes they’re more delicate.

Price: $25
Material: 100% organic cotton
Fit: True to size with a loose feel
Breathability: 3/5 thick fabric that runs warm
Size range: XS to XXXL
Colors: Black, Lilac and Creme Brulee
Styles: Thong, Bikini, Classic Brief, High Waist Brief, Boxers, Maternity

I tried Subset Organic Cotton Mid Rise Brief

Subset’s undies feel a little more premium than Pact and Organic Basics thanks to the higher organic cotton content and nicer bands. Their undies are made with 95% Certified Organic Cotton and 5% elastane and have wider lining all along the edges. They feel just a tiny bit softer than the big brands, but it’s honestly hard to tell a major difference when worn. I think their bras (bralette style) are top of the line, so if you’re looking for a new one it makes sense to get the undies too. They offer a ton of colors and have the most inclusive sizing out of all the brands I tried.

Price: $20
Material: 95% Certified Organic Cotton and 5% elastane
Fit: True to size
Breathability: 4/5
Size range: XXS to XXXXL
Colors: 10
Styles: Thong, Bikini, Brief, Boy Short, Hipster, Maternity

I tried Negative French Whipped Cotton Brief (luxe!)

Negative underwear is by far the most luxurious (and expensive) panties I own. They’re made of 91% micro modal with a 100% cotton gusset lining. They may not be as pure as ones with GOTS Organic Cotton, but Negative’s undies are OEKO-TEX certified non toxic – and they’re incredibly silky soft and breathable. Their Whipped collection wins for breathability and I would rate it a 6/5. Most organic underwear needs to be machine washed cold, but these can handle a warm cycle. There’s at least an inch of size difference between their Boy Short and Brief styles. The medium Boy Short feels like a large to me so I would size down in this particular style. Their medium French Whipped Cut Brief in Medium fits true to size.

Price: $45
Material: 91% Micro Modal 9% Lycra and 100% Cotton gusset lining
Fit: loose fit
Breathability: 5/5
Size range: XS to XXL
Style: Bikini, Thong, Brief, Boxer, Boyshorts, High Rise

I tried Pact Everyday Organic High Rise Brief

Pact was one of the first organic cotton panties I tried and they remain one of the best value for money options today. This is the lowest priced certified organic cotton underwear in my list. I find their underwear soft, stretchy and pleasant to wear but I wouldn’t consider them the highest quality or the most durable.

Price: $16
Materials: 95% Organic Cotton 5% Elastane Body and 100% organic cotton gusset
Fit: True to size

I tried Period Co Period Underwear

If you’re wondering what my favorite organic period underwear is…I’ve tried different non toxic period underwear brands over the years, and my favorite is Period Co’s. These are made with 95% organic cotton and are third party tested to be PFAS-free. The absorbent layer inside where the fabric needs to actually absorb your period is polyester which is understandable. I love that I never experience leaks with this particular brand like I have with others. The underwear has four layers to actually absorb everything and they offer different types depending on how heavy your flow is. Plus, they’re so affordable at around 10 bucks!
