Women's organic cotton activewear, made in our own Los Angeles facility. Every fitted piece in this collection uses our PureFlex fabric: 92% GOTS-certified organic cotton with 8% spandex for stretch and shape recovery. We had the fabric independently tested for PFAS and we publish the result, and every garment is knit, cut, sewn, and dyed in Los Angeles. No synthetic shells, no chemical performance coatings, no black-box supply chain.

Find Your Piece by Activity

Yoga and Pilates

High-waist leggings stay put through inversions and long holds, and the racerback sports bra keeps straps off your shoulder blades. Cotton's breathability matters most in slow, warm practices where synthetics turn clammy.

Strength training

The high-waist and pocket leggings use a thicker knit with a waistband that doesn't roll under a bar. Choose your true size: sizing down adds tension and can reduce opacity in a deep squat. Pair with the high neck racerback bra for more coverage under movement.

Walking, errands, and everyday

Mid-rise and bootcut leggings wear like your favorite pants, and the pocket styles carry a phone properly. The Reversible Pivot Top is the fitted match, with two looks in one because it reverses.

Warm weather

High-waist shorts and the cami crop top keep the same 92/8 fabric in less coverage. Cotton absorbs sweat instead of smearing it around, which is exactly what you want in heat.

Why PureFlex Instead of Polyester

Most activewear is polyester or nylon with chemical finishes. PureFlex takes the opposite approach: organic cotton as 92% of the fabric, just enough spandex for recovery, and no coatings at all. Cotton breathes, softens with washing, and doesn't hold the odor that makes synthetic gym clothes smell again the moment you warm up. The honest trade-off: for long, high-sweat endurance sessions in the rain, fast-drying synthetics still have a place. For everything else, cotton is the more comfortable choice, and we compare the two in detail in our cotton versus synthetic workout clothes guide.

Claims You Can Check

The fabric is GOTS-certified organic cotton, grown in Texas, Turkey, and India. On PFAS we publish the test result rather than a blanket claim: in October 2024, Applied Technical Services, an independent testing laboratory, screened our organic cotton leggings fabric and found no PFAS detected, measuring total fluorine at below 2 parts per million against a current industry threshold of 100 ppm. Read the full lab report. We design, cut, sew, and finish every garment in our own Los Angeles building, and we are a licensed California garment manufacturer, registration GA-LR-1001309619; Los Angeles partners handle the knitting and garment dyeing. PuraKai is a father-and-daughter founded business, independent since 2012, with no venture capital and no private equity.

Frequently Asked Questions

Is cotton activewear good for sweaty workouts?

Cotton handles most gym sessions well: it absorbs sweat rather than pushing it around, so it feels dry against the skin through a typical workout. For long, high-sweat endurance sessions it takes longer to dry than synthetics, which is the honest limit. Our cotton gym clothes guide maps it activity by activity.

What is the fabric in this collection?

Fitted pieces are PureFlex: 92% GOTS-certified organic cotton and 8% spandex. The spandex provides the stretch and shape recovery a fitted garment needs; the cotton provides everything else. Nothing in the collection uses stain-resistant, water-repellent, or antimicrobial chemical finishes.

Where is PuraKai activewear made?

In Los Angeles, California. Design, cutting, sewing, and finishing happen in our own facility; knitting and garment dyeing are done by Los Angeles partners. The organic cotton is grown in Texas, Turkey, and India.

How should I care for organic cotton activewear?

Cold wash, air dry, and skip fabric softener, which coats stretch fibers. Cared for this way, the fabric softens with age instead of pilling.
