Sustainability & Impact

The first layer. Our journey. We care about the world around us, and we know that you do too. That’s why we want to be as honest as we can be with you about the path we are on as a sustainably-minded brand, both in terms of what we are doing well and what we are seeking to improve.

Sustainable Materials

We work tirelessly to source new and innovative fabrics that will offer our customers the best fit and performance. We also ensure that we select sustainable materials where possible and are committed to continuing our education and innovations in this area as new fabrics and fibers become available. We provide both natural and high tech, lightweight fabrics that you can feel comfortable in everyday.


Silk is one of the strongest natural fibers, which uses less water, chemicals and energy than many other fibers.  Silk also absorbs moisture effectively and is breathable. It stays cool in warm weather and warm in cold weather, making it a perfect material for underwear and camisoles.


We source the majority of our silk in China, which is where silk production originated many thousands of years ago.  The Chinese are masters in working with this luxurious material and it is most efficient and environmentally beneficial for us to utilize a fabric that can be procured near our manufacturers.


While silk is a natural and biodegradable fiber, we recognize that it does have its own environmental impact and comes from the silkworm.  We consistently measure the benefits and costs of each of our material choices .While we are utilizing this renewable resource at the present time, we will continue to review the combination of needs for our product fit and function and sustainable fabrics.. 

Our silk pieces can be hand washed with cold water or machine-washed on the cold cycle and hung to dry to save on energy.


Our Happy Seams collection is made of OEKO-TEX® certified materials, ensuring that the fabric has been tested for harmful substances and is harmless for human health.

Eastman Naia™ 

Naia™  is a sustainable cellulosic fiber made from wood pulp and a sustainably sourced natural fiber cotton-alternative. This innovative, traceable and biobased fiber has a low environmental impact.  Naia™ is created from sustainability managed pine and eucalyptus trees and produced in the United States via a closed-loop process.  Naia™ has received the OEKO-TEX® STANDARD 100 certification as a Class I product and is made with no hazardous chemicals listed on the ZDHC Manufacturing Restricted Substances List.  We use Naia™ in our loungewear and chemise and these pieces can be washed at home.  Naia™ is perfect for these garments as it is breathable, cool to the touch, hypoallergenic and quick drying, and most importantly of all is extremely comfortable.


CiCLO® technology is a patented and scientifically proven solution that allows synthetic textiles to behave more like natural fibers when they end up as pollutants in the environment, without compromising on durability.

Packaging & Production

As with other areas of our business, we continue to innovate our packaging and strive to maintain top quality manufacturing partners.  When paper packaging is needed, we only use FSC-Certified materials, and we have also switched to biodegradable packaging where possible to eliminate polybags. We also continue to look into new packaging options such as 100% recycled paper mailers that may provide even greater environmental benefits.


We have partnered with a leading production group to ensure we work with audited factories that help oversee local production partners in the region to provide favorable working conditions. Our larger factory is audited annually following BSCI standards. We use sea freight whenever possible, instead of air freight, which reduces the carbon emissions in shipping.

Paper Packaging

FSC Certification ensures that from the forest to the factory floor, our packaging is responsibly managed at all stages of the supply chain. We also ensure that our hang tags, tissue paper and stickers are FSC certified as we are committed to creating the least amount of waste possible when mailing our products. 

Biodegradable Clear Bags

We have partnered with Mainetti, a leader in packaging solutions, to find a solution for the plastic polybags that are ubiquitous in the apparel industry.  We are utilizing their M-filmTM Land flexible packaging which responsibly biodegrades in a landfill due to an organic polymer called BDP that changes the packaging properties in anaerobic conditions.  More information can be found here on if you are interested in learning more about being a part of the solution to reduce plastic waste.

This product has been tested via ASTM D5511 and complies with ASTM Standards. This is not recognized in the state of California as California law prohibits the labeling of any plastic products that do not meet its requirements for "compostable" or "marine degradable."

Community Support

How Customers Can Help

We encourage all of our customers to aid in Uwila Warrior’s sustainability journey.  You can reuse or recycle the mailer your products are packaged in, as well as the tissue paper it comes with.  Our clear bags can be put in the trash and will responsibly biodegrade in a landfill.  You can also recycle the clear bags at certain drop off locations, which can be found here at  

You can recycle or donate your Uwila bras and camisoles when you are done wearing them.  Find out information on our newest partner program below

At Uwila Warrior, part of our core mission is to help you solve problems, including the end of life issues that face fashion generally and underwear specifically. That’s why we’re teaming up with For Days to offer their Take Back Bags on and in our Boston store.

Here’s how it works:

Order a Take Back Bag for $20, clean out your closet, and send back your filled bag. You'll earn $20 in Closet Cash credit towards your next purchase on for every Take Back Bag you order.
