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.
Frequently Asked Questions
PuraKai aims to create eco-friendly, sustainable clothing that is both stylish and comfortable, using only natural fabrics that begin and end in the soil, avoiding the shedding of microplastics. We also actively support environmental initiatives and ocean conservation.
PuraKai garments are designed, cut, sewn, and finished in our own Los Angeles facility, with knitting and garment dyeing handled by Los Angeles partners. Our Texas-Grown All American line follows its own documented route: organic cotton grown in Texas, spun in North Carolina, knitted in South Carolina, and sewn in Georgia.
We primarily use organic cotton, hemp, merino wool, and lyocell. We started with cotton grown in California and have since expanded to using GOTS organic cotton from India and other natural fibers.
Our All American Project uses Texas-Grown organic cotton made in North Carolina, South Carolina and Georgia, all within a 1,350 mile supply chain from seed to clothing.
To mitigate the environmental impact of microfiber shedding, PuraKai has committed to using only natural fibers that are biodegradable and integrate back into the soil at the end of their lifecycle, except for our activewear, which requires a small amount of spandex.
We have donated a portion of sales to environmental and ocean nonprofits every year since 2012, including organizations working on plastic pollution such as 5 Gyres.
We currently do not offer international shipping.
We recommend following the care instructions provided on the label of each garment to ensure the longevity and maintain the quality of your PuraKai clothing.

Nice material, great fit!
Quality fabric!!
Fit perfectly and was comfortable
Comfortable! My go to sports bra is usually Lululemon, Like a Cloud (size 8 or 10). I usually wear it for pilates. This sports bra. This held up just as well! I ordered a medium and it fit well, slightly snug but still comfortable. I truly appreciate knowing I've made a healthier choice for my body by choosing Purakai!
Love these - purchased in 3 colors. I'm 5'1 and 110lbs w/ a wider ribcage. Ideally, I'm probably a size between S and M, but ended up going w/ the S instead of hoping the M would shrink enough. I hang dry and it's still perfect after a few washes. Feels so much nicer than synthetic material. Would definitely recommend.
Finally found a great sports bra that supports but doesn’t squish my boobs and the cut is just right. I love the fabric and how the bottom elastic is nice and snug and supports my lactating breast while the body provides support but also doesn’t squish. I tried mate the label ones and the cut was just bad. These aren’t too low and have a nice wide underarm area. I’ll definitely buy a few more. For reference, I am 5’2” and 115lbs about a 34C. I ordered a size S.
Very comfortable and supportive. True to size.
I am a yoga instructor and wear yoga clothes every day. I loved the sports bra I received. It fits well and is super soft and comfortable.
Finally a supportive sports bra that's mostly cotton! Love it!!!
I’m usually inbetween a L or XL in most sports bras so I went with XL and the elastic around the waist felt a little uncomfortable after wearing for a few hours. Great to wear for a workout but I wouldn’t want to wear it all day. The feel of the fabric is very comfortable though!
Nice material. Seems very durable.
Great material and I wanted to love it. I got an XS because I'm very small, but it was too tight and rode up too high under my arms to be comfortable. A size S might have worked but they were sold out, so I returned the XS.
Love the fabric and the structure. Unfortunately this bra is not made for anyone over a b cup- there simply isn’t enough material to cover or hold larger breasts. Thus my search for an organic cotton sports bra continues as most brands offering organic cotton clothing are not size inclusive.
Bra was too high into my armpit. Uncomfortably. Liked the feel Of the material but did not work for me.
Bra is too tight and not supportive enough.
It is much too thick and too big of a profile
The proportions were off. It was too wide in the straps yet tight at the bust. Just not a fit for my petite frame.
