Using innovative technologies to reduce our impact on the environment, EDWIN USA is shaping the future of sustainable denim manufacturing.


EDWIN USA is responsibly manufactured at Saitex. Based in Vietnam, Saitex is the first B Corp-certified factory in Asia and the only large-scale denim manufacturer to meet the standards set forth by B LAB. Committed to creating a circular economy to not only reduce impact but also bring real benefit to the environment and communities, Saitex has also received bluesign, LEED and Fair Trade certifications, among others. As a Fair Trade-certified factory, Saitex upholds internationally recognized labor standards, providing its employees with living wages, ensuring ethical, respectful working conditions and employing sustainable production methods. In the winter of 2020, Saitex will open an additional factory in Los Angeles, where EDWIN USA will also be produced, helping us create jobs for local workers and further reduce our carbon emissions.

EDWIN USA jeans are made with just 1.5 liters of water, compared to the industry standard of 80 liters


Saitex is a zero-discharge facility, recycling 98% of the water it uses (the remaining 2% is evaporated), which means that EDWIN USA jeans are made with just 1.5 liters of water, compared to the industry standard of 80 liters. This filtration method is called reverse osmosis, and filters all indigo and fiber residue out of the water. The result is purified water that is cleaner than your average drinking water. This closed-water system saves 450-million liters of water per year, which is the equivalent of the annual water consumption of 432,000 people.


By conserving energy, Saitex saves 13-million kWh per year


Our jeans are made with clean alternative energy sources: 40% of the electricity Saitex uses comes from solar and hydropower, and 100% of the heat it uses comes from biomass generators that burn wood shavings and coconut husks instead of fossil fuels. This means that 5,844,575 kilograms of fossil fuel use was avoided in 2019. Our jeans are then air-dried in an aerial drying system, which is a simple conveyor: garments hang in the upper area of the factory for up to three hours to dry. This process reduces the dryer time from 105 minutes to just 25. By conserving energy, Saitex saves 13-million kWh per year and has reduced is C02 emissions by nearly 80%. To further offset its footprint, Saitex has planted 6,000 trees in the industrial area, and plans to be carbon neutral by 2023.

EDWIN USA jeans are made with innovative manufacturing techniques, such as lasers that etch natural wear marks on denim. Laser transforms a 20- to 30-minute manual process to just 90 seconds, and replaces the conventional use of sandpaper and the chemical potassium permanganate to create a worn-in effects on jeans. This laser process helps to create consistency in the work, minimizes difficult manual labor and reduces chemical usage.


Saitex utilizes robots and automation to mechanize sustainability and consistency in production. Automation replaces unpleasant work done by humans, reduces their contact with chemicals and exacts efficiency of the applied effects, reducing both time and waste.


E-Flow technology is used in many of our EDWIN USA wash processes. E-flow takes the air from the atmosphere and transforms it into nano-bubbles. Saitex then applies resins, enzymes and other chemicals during the denim wash process to break up the surface of a garment and to achieve soft hand-feel. By using E-flow technology instead of the traditional washing methods, 98% of water is saved and energy consumption drops by 47%.


We at EDWIN USA use an ozone air (natural gas) finish on many of our washes. Ozone technology acts as a mild bleaching agent as well as a sterilizing agent. It uses the natural bleaching capabilities of ozone gas to give a desired wash effect with substantially reduced environment impact. The process: oxygen (O2) is converted to ozone gas (O3), jeans can be dry or dampened with water, exposed to the ozone, and rinsed; the ozone is reconverted to ordinary oxygen before being released into the environment. Chemical bleaching or stone washing can take up to six washes and rinses cycles, while ozone finish can reduce the wash cycle to as little as two to three washes.   Ozone technology does not eliminate water usage, however, it does substantially reduce the consumption of water as well as energy, chemicals, enzymes and stones.

At EDWIN USA, we believe in the power of innovation.


To further embrace circularity and tackle waste by giving new life to garment offcuts and deadstock, Saitex is building an upcycling facility in Thailand called STELAPOP (an acronym for Save Trees, Eliminate Landfills and Protect Our Planet). Using a proprietary binder, STELAPOP transforms discarded denim into multipurpose panels that can be used in the place of wood to build furniture. STELAPOP will have the capacity of upcycling 12,000 garments per month, which will help fight deforestation and reduce landfill waste for a regenerated future.


SAITEX donates 0.1% of its revenue to social impact, which helps to support 603 children and adults at three orphanages and one disabilities center in Vietnam. In addition, SAITEX founded Rekut, a social entrepreneurship project that provides fair pay and respectful working conditions to differently abled people. The Rekut production line currently has 35 fulltime employees with different abilities, both physical and developmental. Each received five months of training, and are now fully independent on the production line, from sewing and embroidering to packing, making products such as apparel, furnishings and face masks.

For a limited time, EDWIN USA is offering a complimentary face mask as a gift with every purchase. To create these masks EDWIN USA is partnering with The Rekut Production Line, a one-of-a-kind production space created to give individuals who are differently abled the opportunity to receive training and work a sustainable job with equal pay and dignity. In addition to helping create a safe space for the differently abled to work and thrive, Rekut is committed to using upcycled materials and products to help tackle the problem of waste and pollution commonly created by the garment and PPE (personal protective equipment) industries.

Constructed using durable dual layer antimicrobial stretch fabric and elastic straps to provide a comfortable form fitting layer of protection. Rekut has helped to craft these masks using excess fabric and eco-friendly dye to minimize environmental impact. Cloth masks are not medical grade protective equipment but are recommended by the CDC in conjunction with other safety steps such as handwashing and social distancing to stop the spread of disease.

In its continuous mission to create positive social impact, the factory also created Saitex Farms, a non-GMO, zero pesticides farm in three on-site containers and one greenhouse. The farm produces six tons of clean fruits and vegetables per year, providing 5,300 people with access to clean and healthier food.
