Live Pure. Wear Pure. Move Pure.
Pure 100% Organic Cotton Basics - PureFlex Organic Cotton Activewear, 92% Organic Cotton, 8% Spandex. Third-party PFAS-tested. Made in USA
Cotton leggings that actually perform. Every pair of PuraKai leggings is made from our PureFlex fabric: 92% GOTS-certified organic cotton and 8% spandex, so natural fiber sits against your skin while the stretch keeps up with squats, yoga, and errands. We had the fabric independently tested for PFAS, and every pair is knit, cut, sewn, and dyed in Los Angeles, California.
Why cotton instead of polyester? Cotton breathes, doesn't trap odor the way synthetics do, and skips the plastic microfibers that shed from polyester leggings in every wash. If you're switching away from synthetic activewear, start here.
Choose from high-waist, high-waist with pockets, mid-rise, bootcut, and capri cuts, true to size and built for years of wear, with sizes XS to XXL depending on style.
Organic cotton leggings FAQ
Are these 100% cotton leggings?
They're 92% certified organic cotton and 8% spandex. We blend in just enough spandex for stretch and recovery; 100% cotton leggings bag out at the knees and lose shape. The fiber against your skin is organic cotton.
Have these been tested for PFAS?
Yes, and we publish the result rather than a blanket claim. In October 2024 an independent testing laboratory, Applied Technical Services, screened our organic cotton leggings fabric for total fluorine, the limiting marker for the entire PFAS class. The result was none detected, below 2 parts per million, against a current industry threshold of 100 ppm. Read the lab report. The fabric is also GOTS-certified, which restricts harmful processing chemistry, and we use no DWR coatings or fluorinated finishes.
Where are they made?
Every pair is knit, cut, sewn, and dyed in Los Angeles, California. PuraKai is a licensed California garment manufacturer, registration GA-LR-1001309619. Our organic cotton is grown in Texas, Turkey, and India.
Do any styles have pockets?
Yes. The PureFlex High-Waist Pocket Leggings have deep side pockets that hold a phone securely through a full workout.
How do they fit and how should I care for them?
True to size with a soft, close feel rather than rigid compression. Choose your true size: sizing down adds tension and can reduce opacity in a deep squat. Machine wash cold, hang or tumble dry low. Organic cotton gets softer with every wash and our fabric is pre-shrunk.
Are cotton leggings good for working out?
Yes. Cotton breathes better than polyester and holds dramatically less odor. For hot yoga or very heavy-sweat sessions, cotton absorbs moisture rather than moving it, so it can feel damper than a synthetic wicking fabric.
