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.

We use no DWR coatings and no fluorinated finishes anywhere in our line.

Love these leggings ! So soft and comfy ! They are the kind that you don’t want to take off ! Really really worth it ! I can’t wait to buy another pair !!

PureFlex Organic Cotton High Waist Leggings

As a personal trainer, I wear leggings every day, and I hate knowing that I’m spending hours working and sweating in fabrics that may contain unwanted chemicals. So, I went on a hunt for cotton leggings that checked all my boxes—and I’m picky! I’ve tried other brands of “non-toxic” leggings and was sadly disappointed. However, Purakai did not disappoint! These leggings fit perfectly, stay in place while I’m working out, are breathable, and aren’t see-through. They check every box for me! I’ll definitely be replacing my other leggings with these. So happy I found these!

Customer video review of PureFlex Organic Cotton High Waist Leggings

Sorry for a blurry messy bathroom video! But these leggings are amazing! This is my second pair. I switched to the 23 inch and they are perfect!!!! . I got them in medium and worried they would be too tight but they are a perfect fit I’m 5 ft 4, 150 pounds. I am going to get them in another color soon!

Customer video review of PureFlex Organic Cotton High Waist Leggings

LOVE LOVE LOVE! I've been looking for stretchy, but nontoxic leggings with GOOD quality forever! These are the ones - I'm obsessed! They're just the right height and feel amazing. They are on the thinner side, but I actually prefer that to wear daily and during workouts. They are NOT see through. Oh, and customer service is absolutely amazing - they take care of you and really work hard to build client relationships! Very happy and can't wait to get more.

PureFlex Organic Cotton High Waist Leggings

I absolutely love that you have embraced and are dedicated to COTTON. I can't stand the synthetics. I am thrilled I have found my "new" leggings go-to! Very well made; perfect soft not-too light, not too heavy fabric. Would love to see some limited edition colors, maybe even tie-dye!

PureFlex Organic Cotton High Waist Leggings

Love them, have tried quite a few organic cotton leggings and these are the only ones that don’t roll down and make me tug at the them the whole time!

PureFlex Organic Cotton High Waist Leggings

These are some of my favorite leggings, I love how they have a length for my height I’m 4ft11in And I love how they are high waisted for tummy control. I just wish they came in more colors.

PureFlex Organic Cotton High Waist Leggings

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.

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!
