WHAT CONSUMERS ARE SAYING:
KEEPS YOU DRY.
Designed to repel moisture, STORM COTTON™ technology is
a durable water repellent (DWR) finish for any cotton
garment that can outlast other standard finishes. Whether
you’re exploring your favorite hiking trails or canoeing down
a river, STORM COTTON™ technology will keep you
comfortable, cool and dry. You shouldn’t have to worry
about your clothes performing so get outside and play –
cotton can handle your favorite adventures, rain or shine.
WATER REPELLENT TECHNOLOGY
BREATHES BETTER THAN
• Repels moisture from the surface
of the fabric
• Maintains the natural comfort and
breathability of cotton
• Dries faster than untreated cotton
• Lasts the life of the garment
• Meets supply chain needs with
clean chemistry options
PROTECTION THAT’S PROVEN
WHAT IS STORM COTTON™ TECHNOLOGY?
STORM COTTON™ technology is a water repellent finish for
cotton that offers protection from rain and snow while
maintaining the natural comfort and breathability of cotton.
The STORM COTTON™ finish gives improved performance
over other durable water repellent treatments by maintaining
excellent repellency performance throughout the life of the
garment. The STORM COTTON™ finish can be applied in
fabric or garment form to knits and wovens, including denim.

as measured by ASTM D737
NO REDUCTION IN
STORM COTTON™ technology is durable throughout the life of the garment, unlike
competing DWR finishes. The spray repellency test measures the resistance of fabrics to
wetting by water. Even after 30 home launderings, the STORM COTTON™ finish remains on
the fabric unlike other DWR finishes. Many water repellent treatments inhibit a fabric’s
ability to breathe and transfer moisture vapor effectively. That’s what is so great about
cotton. STORM COTTON™ technology does not affect the natural ability of cotton fabrics
breathe and keep you cool. Although it repels liquids, the finish still allows moisture vapor
to pass through the fabric where it -can dissipate into the environment, naturally keeping you
more comfortable. Don’t take our word for it. Standardized test methods prove the point.
STORM COTTON™ technology can be applied in both fabric form and garment form. The
fabric application process is done by padding the finish onto the fabric, drying the fabric,
and curing with the necessary time and temperature to achieve the highest level of
performance. In garment form, the finish is applied through garment dipping or
spray application in a garment machine. The garments are then cured at the necessary
time and temperature. The finish is versatile and can be applied to best meet the needs of
your supply chain with suppliers all around the world.

JEANS FOR EVERY ADVENTURE.
STORM COTTON TECHNOLOGY + DENIM
The STORM COTTON™ technology recipe and finishing steps can
be tailored specifically for denim to achieve optimal performance.
Denim is more prevalent than ever – from hiking, casual wear,
skating, biking, traveling to working on the jobsite, consumers are
wearing their favorite pair of jeans anywhere and everywhere.
Savvy consumers expect more from their denim and the STORM
COTTON™ technology elevates performance while keeping the look
and feel that consumers love about their jeans. With STORM
COTTON™ technology, there’s no limit to what your favorite jeans

The STORM COTTON™ finish is primarily applied in garment form. The finish can be
applied to open width fabric, but the most common application is either through
garment dipping or metered spray application. This allows for greater flexibility to apply
various garment finishing techniques to achieve the desired styling and appearance of
the finished product. The garments are cured after the finish has been applied in order
to help set the finish into the fabric.
The STORM COTTON™ technology outperforms a standard DWR
finish when tested for spray repellency and is proven to last the life
of the garment. The spray repellency test measures the resistance
of fabrics to wetting by water.

Proven performance doesn’t have to harm the environment.
Consumers already know cotton is the best fiber choice for the
environment – 91% of consumers consider cotton to be the
safest compared to 45% of consumers who believe polyester is
With the ever-growing challenge of microplastic pollution, your
clothing shouldn’t pose a threat to our earth or our oceans.
Cotton fiber biodegrades in soil and wastewater at a much
faster rate than polyester.
Cotton is known for its quality and
durability, but in the laundry and at the end-of-life, you can feel
better about that cotton garment and its effects on the
environment. Your clothes should love the great outdoors as
much as you do.

Many water repellent chemistries contain fluorinated
compounds to repel moisture and the finish formulas contain
perfluorooctanoic acid, or PFOA. The U.S. Environmental
Protection Agency (EPA) has investigated issues concerning
PFOA and fluorochemicals and there has been interest in finding
alternatives to PFOA.
The standard perfluorinated molecules
contain an 8-carbon chain structure (C8) that does not break
down quickly in the environment.
The STORM COTTON™ technology provides an alternative to the
C8 chemistry: a shorter carbon chain structure (C6) finish and
fluorocarbon-free finish. Performance is not sacrificed and spray
repellency ratings are still able to be met, while providing a
sustainable industry solution for a durable water repellency
WE CAN ENGINEER A SOLUTION FOR YOU.
