Made for anywhere
Cotton is a natural fiber that is commonly used for its breathability and softness. Using organic cotton instead of regular cotton has the potential to build soil health, as it is grown without the use of synthetic fertilizers.
At Delta Textile Shamal el Saeed, they have obtained the Global Organic Textile Standard (GOTS) and Global Recycled Standard (GRS) certifications. They are also certified by WRAP and OEKO-TEX® STANDARD 100, for social and chemical compliance respectively.

"Extremely comfortable! Would love it if they came out with a lower rise version. I do order a size down from the size guide as they run a little big"
"Soft and very thin, which makes them breathable and not hot. Unlike other thin-fabric underwear, these feel sturdy and the seams are well constructed, so I'm hopeful they will last. Fit more like hipsters than organic basics "hipsters", imo. But I like that."
"Very comfy and stretchy, could even be a bit more stretchy for me Nice colours Not very visible under pants Negative: itchy tags inside underwear"
"Good fit. 100% organic cotton feels good. Love the color."
"While the briefs are comfortable, I followed the washing instructions and the waist band deteriorated after two washes. They are still wearable, just a lot less visually appealing. I’m disappointed that they are now occupying the same space in my drawer as my much older undies."
"My new favorite pair of underwear. Really good shape. Not too tight or loose, medium fit. Comfortable and soft fabric. Would def recommend!"
"I‘ve been looking for new underwear for a while now and have found pairs here and there that were fine…. but never something that quite fit the bill. Either not cotton or too snug around the legs or ride funny at the waist. I knew I ultimately wanted cotton but couldn’t seem to find any that would not cause panty lines. I saw an ad for Organic Cotton, read reviews and decided to give them a shot. Man, these didn’t feel like I was wearing anything! But would they still be this good after washing? I did follow the instructions and washed in cold water, low dry but a couple of pairs have slipped into a higher dryer temp and been just fine. These are soo soft, thin yet sturdy seams, nice colors. I only wish I could get them in 6 packs! I’ve already told my friend about them who has been on the quest as well. Will be stocking up!"
"I love these briefs. Medium fit me perfectly, very soft, I am in love with organic basics to be honest, I have started taking my underwear more seriously alongside all my clothes in terms of quality and aesthetic and organic basics fits into that. Simple design, I especially like the colour choices."
"As an organic farmer who cares about what goes in her body, I love knowing that I'm wearing organic cotton underwear right next to a sensitive part of my body."
"I’m obsessed with how comfy these are. I love that it’s cotton. It’s good coverage too."
