Pure 100% organic cotton basics, made in our own Los Angeles facility. This is the collection for people who want all cotton workout clothes and everyday staples with zero synthetic fiber in the body fabric: tees, joggers, and layers knit from 100% GOTS-certified organic cotton, grown from seed to shirt and independently lab-tested PFAS-free.

Every Piece Here Is 100% Organic Cotton

We label fiber content exactly, because "all cotton" should mean all cotton. Everything in this collection, from the Classic Fit Tee and All-Day Crop Tee to the Lightweight and Fleece Joggers and the Texas-Grown pieces, is 100% organic cotton in the body fabric. No spandex, no polyester, no blends. Each product page confirms it.

All-Cotton Workout Clothes, Honestly

For low-impact movement, warm-ups, stretching, walking, and recovery days, 100% organic cotton works beautifully: the relaxed cuts carry the fit, so no stretch fiber is needed. For fitted training pieces like leggings and bras, a small amount of spandex is what keeps them from bagging out, which is why our fitted activewear lives in the PureFlex activewear collection at 92% organic cotton and 8% spandex. Our guide to whether leggings can be 100% cotton explains that trade-off plainly.

Claims You Can Check

The cotton is GOTS-certified and grown in Texas, Turkey, and India. Our fabric is independently lab-tested PFAS-free by Applied Technical Services, an ISO/IEC 17025 accredited lab, and we publish the full lab report. Every piece is designed, cut, sewn, and finished in our own Los Angeles building, with knitting and garment dyeing by Los Angeles partners. PuraKai is a father-and-daughter founded business, independent since 2012.

Frequently Asked Questions

Are these workout clothes 100% cotton?

Yes. Every piece in this collection is 100% organic cotton in the body fabric, and it suits low-impact movement, warm-ups, and everyday wear. For fitted training pieces that need stretch recovery, see our 92/8 PureFlex activewear, labeled exactly on every product page.

Do 100% cotton pieces shrink?

Cotton can shrink with heat. Wash cold and air dry, and the fit holds. Each product page carries the care details for that piece.

Why choose 100% organic cotton basics?

Zero synthetic fiber in the body fabric means nothing to shed in the wash and a garment that begins and ends its life in the earth. The cotton takes eight months to grow; the tee is built to last years beyond that.
