Proven pima purity
from our farms to your family.

It takes the world’s purest American Pima Cotton to make the world’s finest Pima Cotton products. Only PimaCott upholds that purity every step of the way. Our revolutionary DNA tracking system helps ensure purity from farm to shelf. So that the American Pima we grow is the Pima you get. For quality beyond compare. And purity you can’t find anywhere else. Pimacott is the new standard in Pima purity.


Why purity matters

The beauty of American Pima Cotton lies in its extra-long fibers. The purer they stay, the softer and stronger the fabric grows. That's why PimaCott insists on the purity of our Pima. We verify that it's never blended or contaminated. So you know you're getting nothing but the purest Pima possible.
For products that look great, feel great, and stay great.

the look

Pure American Pima Cotton holds color better, fades less, pills less and shrinks less than other cottons. The result is a product that looks newer longer.

the feel

American Pima's ultrafine fibers make ultrafine fabric that can only be described as smooth, luxurious, and amazingly soft.

the strength

American Pima's extra-long strands make for an extra-strong weave. That means Pima products are longer-lasting and less prone to pulling & tearing.

Meet our farmers

Purity starts at the source - the farms of California's San Joaquin Valley, to be exact. Meet a few of the farmers growing our Pima cotton with pure dedication, pure integrity, and pure pride.

A fifth-generation farming family, the Hansen Ranches is headquartered in Corcoran, CA. Phil and his brother Erik oversee the farm where they grow cotton, almonds, pistachios, pomegranates and a variety of field crops.

The Hansen family emigrated from Denmark to California in the early 1900’s. Today Phillip Hansen and his brother Erik manage the day-to-day operations, overseeing 20,000 acres of farmland and over 60 employees.

Phil and his brother Erik started working on the family farm during at the young age of 12 and 13. Their father insisted they try their hands at a variety of jobs to ensure both boys had a full understanding of what it takes to operate a farm. Phil went onto graduate with Bachelors degree in Agricultural Business Management from Cal poly San Luis Obispo in 1989 while Erik graduated with his Bachelors degree from Utah. They both returned to Corcoran following college to work full time on the farm.

Today Phil is President Hansen Ranches, still working closely with his brother Erik who is the GM of Farming Operations and Water Conservation along with their cousin Nis Hansen who oversees the all the farms equipment. Phil and Erik both serve on numerous boards including: Tulare Lake Water storage district, Supima, Superior Almond Hulling, Horizon Nut and the Corcoran Community Foundation. In addition to their board appointments, Phil is also the Current Chairman of California Cotton Growers association, while Erik donates a good majority of his time to Agricultural Education through the EAT foundation.

J&J Farms is a third generation family farm that has been in operating in the San Jaquin Valley since 1949 where they farm 7,300 acres of Pima cotton, pomegranates, processing tomatoes, wine grapes, and other commodities.

The farm was founded by CW “Bill” Jones and his wife Cora Visman Jones, both World War II veterans and UC Davis graduates. CW was instrumental in the creation of the Delta Mendota Water Authority, that overseas the Central Valley Project that transmits water to millions of acres of farm land and cities such as Los Angeles and San Diego. The Jones Pumping plant in Tracy, CA that moves the water South was dedicated to him for his years of service in 2007.

In 1987, his son, William Leon Jones as a member of the California State Assembly authored the bill that brought Pima Cotton to California. Prior to that time, California operated under the “One Variety Law” that gave California growers a small premium for their crop. Today, California grows nearly all of the US grown Pima thanks to his efforts.

Today Bill manages the family farm where Pima is the only cotton they grow. With the help of his brother, Ron Jones and his nephew, Darcy Villere, the family looks forward to many more years of providing Pima to the world.

A sixth-generation farmer, Cannon Michael is president of Bowles Farming Company headquartered in Los Banos, Calif. There, he oversees an 11,000-acre farm where the company grows cotton, fresh market and processing tomatoes, field crops, and other commodities.

Michael’s great-great-great-grandfather was Henry Miller, a German immigrant whose partnership with Charles Lux became known as Miller & Lux and resulted in the build-up of landholdings in the San Joaquin Valley to more than 1 million acres.

Michael began working on his family’s farm at age 13 during the summer months. After college, he worked in commercial real estate in Atlanta. He returned to California in 1998 to become the shop foreman at Bowles Farming Company under his uncle, Philip Bowles, and rose to vice president of business operations in 2002. Bowles retired at the end of 2013, when Cannon became president.

Michael serves as a director San Luis Canal Company, and as president of the San Luis Resource Conservation District. In addition, he is a director for the California Tomato Research Institute, the chairman of the California Cotton Growers Association.

He earned a bachelor’s degree in English from University of California, Berkeley, and graduated from the California Agricultural Leadership Foundation program in 2010.

Established in 1988 in Los Banos, CA, A-Bar Ag Enterprises is family owend and operated by Arnold Barcellos and his two sons, Aaron and Aric. Today the Barcello’s farm has grown to 7,000 acres where they grow Almonds, Asparagus, Cotton, Pistachios, Pomegranates, Tomatoes and other commodities.

Giving back to the communities in which we live and industries that support our business is a belief long held by Arnold. He is a graduate of one of the first classes of the California Agricultural Leadership Foundation, Board Member of Yosemite Farm Credit for more than 30 years, former President of the Western United Dairymen's Association and he has spent over 20 years as a director on the Resource Conservation Board.

Aaron has followed in his father's footsteps. He's also a graduate of the California Agricultural Leadership Foundation, current Chairman of the Cotton Board, Vice Chairman of the California Tomato Growers Association, President of the Pacheco Water District and past President of the Los Banos Unified School Board.

Some of the organizations A-Bar Ag Enterprises is proud to support include: Community Food Bank, National Alliance on Mental Illness, American Cancer Society, Future Farmers of America, California Farm Bureau, along with several additional local charities and organizations.

The Britz family is now entering its third generation. Founders Albert and Helen Britz began the operation as Fertilizer distributors in the early 1950s at Five Points, California. There they raised their three children David, Linda and Martin at a home inside of the Fertilizer Plant. The farm has expanded to include other Fertilizer locations and farming properties on both the West and East side of the San Joaquin Valley. Linda, David and Martin all remain active owners and operators of the business.

The family was joined by Linda’s husband Robert in 1978. The three families have run the businesses since then growing all of their business operations. The Fertilizer Company sales grew 10 fold between the 1980s until its sale to J.R. Simplot in 2008. The farming operations grew to include up to 15 different commodities from then until now. The family grows, processes, and market directly Onions, Stone Fruit and Citrus products. They grow and market almonds and raisins through Coops as well as wine grapes marketed though Gallo for over 50 years and other wineries.

Cotton has always been one of the major commodities grown by the family. The original Britz Upland Gin was built by the family in 1979. The current Britz Mt. Whitney Gin was acquired in the early 2000’s to facilitate the production of Pima cotton. The family has always welcomed friends and Fertilizer clients to gin with them.

A 3rd-generation farmer, Kirk Gilkey is president of Gilkey Farm Inc. located in Corcoran, Calif. Kirk’s grandparents came to Corcoran in 1922 to start custom farming. Today Gilkey Farms is one of the largest cotton farms in the San Joaquin Valley.

Kirk’s father, Don Gilkey, was a star football player at the University of California, Berkeley, who passed up a promising pro career to return to run his family’s farm in Corcoran instead. Don was honored as King County’s Agriculturalist of the Year in 2005.

Following in his Dad’s footsteps, Kirk serves as President of the California Cotton Ginners Association where he served as chairman in 1996. He is also the manager and partner of Cross Creek Ginning Co., a modern saw/roller combo gin in Corcoran. He was named California’s “Ginner of the Year” in 2000.

Pure by nature.
Proven by science.

We start with the best Pima Cotton in the world, cultivated in the perfect conditions in the San Joaquin Valley, California. We then tag our cotton, using a revolutionary DNA tracking technology which allows us to trace it from the source to finished product. Only PimaCott can guarantee that you’re getting the pure Pima cotton you’re paying for.

We’ve got purity down pat!

Anyone can tell you how Pima Cotton is processed. What they won’t tell you is how it can bediluted with inferior cotton along the way. Only PimaCott ensures that your American Pima stays pure from start to finish. We do it proudly with the help of nature, nurture and the revolutionary science of SigNature T DNA.

Farm the Cotton

The cotton is grown and picked in pristine California farmland, family owned and operated for generations. After harvesting, the Pima seed-cotton modules are transported to a nearby cotton gin.

Gin the Cotton

Once the Pima Cotton arrives at the gin, seeds (and other impurities) are separated from the cotton fiber.

Tag/Spray With SigNature® T

At the end of this process, SigNature® T DNA, a botanical-based marker is applied through a fine misting process. This marker permanently attaches to the fiber at a cotton-to-marker ratio of 1:1 billion. The tenacity of marker ensures a reliable, secure tracking system throughout the entire manufacturing process, beginning in the U.S., and through the spinning, weaving and sewing stage overseas.

Bale Cotton

Harvested, ginned and tagged, the Pima Cotton is then compacted into 500-pound bales that are barcoded and tracked by PimaCott to prevent product tampering.

Test Fiber

The first check of the pima cotton fibers happens at the gin. PimaCott submits the bales for testing, looking for the unique SigNature® T DNA marker. The merchant then receives the bales from the ginner together with test result, the bale ID numbers, and USDA grading certification.


The bales of PimaCott start their journey overseas for the next stage of product manufacturing.

Spin Into Yarn

Spinners receive and separately store the PimaCott bales and then spin the raw cotton fibers into yarn on dedicated lines.

Test Yarn

After spinning fiber into yarn, PimaCott once again tests the yarns for the SigNature® T marker, to ensure that no cotton blending has taken place. These tests are done before the yarns are permitted to move to the weavers.

Weave or Knit Into Fabric

The pure PimaCott yarns finally takes shape and is woven or knitted into fabric to be used in various textile or apparel products

Test Fabric

Guaranteeing purity, the freshly woven fabric is once again tested by PimaCott for the SigNature® T marker to verify that the fabrics contain only the tagged Pima Cotton.

Cut & Sew

After passing the purity test, the PimaCott fabric is then cut and sewn into the finished home textile or apparel products.

Test Finished Product

PimaCott does a final test of the finished products prior to the product being shipped back to the United States. Specifically, PimaCott looks for the SigNature® T DNA markers that have remained detectable, even after many complex manufacturing processes.


Having passed the final purity test, the finished, pure PimaCott products are shipped and tracked with a pedigree document back to the United States.


The finished goods, labeled with the PimaCott trademark, arrive at retail where consumers, driven by a desire for a quality and purity, can be assured of the integrity of their purchase.


The customer enjoys the finished, PimaCott product, where it's purity has resulted in a product with noticeable improvement in softness, wearability and longevity.
