How to choose your size

Most styles run true to size. PureFlex and Pure are garment dyed and pre-shrunk, so choose the size you normally wear.

Between sizes? Take the larger one. Sizing down puts more tension across the seat, which reduces opacity in a deep squat.

Need a different length? Change the inseam, not the size. Leggings come in three inseams and shorts in two, so a shorter inseam at your true size will fit better than a smaller size.

Shorts: check the measurements at your hip rather than the size you usually wear in shorts.

Bras and tops: your usual size for a secure fit, or size up if you prefer less compression.

Pure Lightweight Joggers: these fit closer than the name suggests. If you want a relaxed fit, size up.

Texas-Grown and EcoLuxe styles: use the measurements on the chart above.

Initially, I was concerned that maybe these leggings would slide down. They stay in place and are very comfortable! The feel is very soft and I can move easily with everything staying in place. Great quality and customer service!

I'm 5 feet tall and weigh 112lbs. These leggings aren't too long and don't look weird when I hike up the fabric a bit. I love the Tidal Teal color!

I bought these as a layer of warmth beneath ski pants. They hug nice and tight and are breathable. The 2x fits my 5-foot-6, 200 lb frame.

Tested and Trusted

We had our bestselling leggings independently tested for PFAS by Applied Technical Services. Total fluorine, the limiting marker for the entire PFAS class, came back none detected at below 2 parts per million.

The report covers the main fabric of our organic cotton leggings, tested in October 2024, against a current industry threshold of 100 ppm. We publish the result rather than a blanket claim.

Why go the extra mile? PFAS are synthetic chemicals used to make fabrics stain and water-resistant, but they’re also known as “forever chemicals” because they persist in the environment and accumulate in our bodies. With PFAS linked to health risks, we made it our goal to guarantee skin-friendly comfort that eases your body and mind.

I love these leggings! They are so comfortable and much cooler than my synthetic ones! I don't even want to wear those anymore! Would love to see more colors!

PureFlex Organic Cotton High Waist Leggings

I love these leggings. They have good stretch and are comfortable. I got a small but would probably go for an XS next time. They have some extra space.

PureFlex Organic Cotton High Waist Leggings

Plenty big for me (M) (I’m 5’4” 126lb) not sure if they shrink though. Wiped a spot off with wet washcloth and black dye came off on the cloth! I’ll be sure to wash with like colors. Very comfortable, balanced compression throughout garment. Nap was malleable as in you can make a design in the surface and it stays until you smooth it out. Assume that element may wash out. I’ll wait for final assessment after laundering.

PureFlex Organic Cotton High Waist Leggings

I always feel it’s risky to buy clothing online. But I took a chance with these and I’m so glad I did. These are beautiful. The material is wonderful. It’s mostly cotton with a little spandex. They stay up great and I can’t say enough good things about it. This will become my standard legging and I will order more pairs pretty soon. Buy with confidence these are high-quality.

PureFlex Organic Cotton High Waist Leggings

Fabric is wonderful, cotton but still form fitting. It's a bit too high waisted for me but I like the seamless waste and so I can easily just fold it a little. Perfect mix between 100% cotton leggings and typical plastic leggings.

Customer video review of PureFlex Organic Cotton High Waist Leggings

These are absolutely incredible!!! They compress just enough, they breathe luxuriously, and Yoga in these leggings is a transcendental experience. Thank you for making such an incredible product!

PureFlex Organic Cotton High Waist Leggings

I love these leggings so much. They are so soft, supportive and stretchy. I am a size 25 in AGOLDE and 26 in Mother denim and a 34" hip and got a size small. Mahalo for your intentional works of art.

Customer video review of PureFlex Organic Cotton High Waist Leggings

I loved is super comf and stretchy very well, the best part is organic cotton good for my body and super stylish. Is amazing pants and top.

PureFlex Organic Cotton High Waist Leggings

I'm 5' tall and weigh 112lbs. These leggings aren't too long and don't look weird when I hike up the fabric a bit. I love the Tidal Teal color and look forward to them offering more colors in the future!

PureFlex Organic Cotton High Waist Leggings

I like the fact that the leggings are 98% cotton and they feel so good. And healthy. Better for the body. Im try=illed to have mine.

PureFlex Organic Cotton High Waist Leggings

Initially, I was concerned that maybe these leggings would slide down (I should note that leggings are not my favorite piece of clothing, but I needed them for a specific gym class). They stay in place and are very comfortable! The feel is very soft and I can move easily with everything staying in place. Great quality and customer service!

PureFlex Organic Cotton High Waist Leggings

I bought these as a layer of warmth beneath ski pants. They hug nice and tight and are breathable. The 2x fits my 5’6 200 lb frame.

PureFlex Organic Cotton High Waist Leggings

I’ve tried many organic cotton leggings and I feel like these are my favorite and the ones I pick first. They’re comfortable, they wash well and I love the way they look on!

PureFlex Organic Cotton High Waist Leggings

I love these and will eventually get more. They are soft, not too tight, especially around my waist, and don't slide down. With another brand of the same size, they are way more compressive but also slide down, so I feel like I have to keep pulling them up and adjusting them constantly. These will be my go-to now. They are not shiny and attract more stuff than synthetics, but I don't care about that. It's nothing obvious or crazy. For reference, I am 5'2", about 115lbs and ordered a size small. Fits great!

PureFlex Organic Cotton High Waist Leggings

I have three pairs of leggings from Purakai and this pair was by the far the best. First two pairs were thicker than the third pair. The length is good for the summer. 5’4 and they’re a few inches above my ankle.

PureFlex Organic Cotton High Waist Leggings

These are the best yoga leggings I've ever owned! The material is so buttery soft and such a bonus it's organic cotton. The fit is amazing. The stretch is so comfy. I am 5ft 1", 115 lbs. and I ordered a medium in ankle length (which fits me like normal length.)

PureFlex Organic Cotton High Waist Leggings

First off, these are some of the comfiest leggings I’ve ever worn. They’re super soft and stretchy, but they don’t stretch out and lose their shape then start to look weird around the crotch area. That’s the usual problem I’ve run into with natural fiber leggings in the past. I bought these in a size up from my usual because I’m pregnant and want to wear them throughout pregnancy and early days of postpartum and I think they’ll work perfectly as my belly grows more! The waist/belly band is quite high and very supportive. It also stays in place during workouts! I’m 5’4” and the shorter length looks great, a tiny bit cropped which I like. They took a bit longer to arrive than I thought, but I emailed them and they replied promptly with the new expected shipping date and the leggings arrived shortly after that. I’m very content with the customer service I received, especially seeing as it’s a family run small business. All in all, I’ve had a great experience with this product and this company. These are fantastic leggings that I’ll be buying more pairs of!
