Our Materials

We choose each material with intention and care to produce responsibly made products. When sourcing for our designs, we prioritize natural, recycled, and organic fibers and do not use any fur, leather, or feathers. We design with circularity in mind, choosing mono-materials and materials that can be easily recycled when possible. Currently, 100% of our swimwear is produced using recycled nylon or recycled polyester. However, we understand that even recycled synthetics are resource intensive and shed microplastics and therefore we are continually exploring more sustainable alternatives to synthetic materials that offer the same quality and performance. We track our material usage and progress annually as part of Textile Exchange’s Corporate Fibers and Materials Benchmark, view our latest report here.

Natural Fibers

ORGANIC COTTON
We source certified organic cotton, which is grown without the use of pesticides or synthetic fertilizers and requires less irrigation as it relies mainly on rainwater (1). Avoiding harmful pesticides preserves soil biodiversity and protects the health of surrounding communities (2). Our organic cotton fabrics are made using organic cotton yarns that are certified by the Global Organic Textile Standard (GOTS). Widely recognized as the gold standard of sustainable processing for clothing and textiles, GOTS certification verifies the organic content in materials and ensures that environmentally and socially responsible manufacturing practices are followed at every stage of manufacturing.

RECYCLED COTTON
We are expanding our use of recycled cotton throughout our collection. Recycled cotton uses less water and energy than growing and manufacturing new cotton products (4) while giving new life to existing materials that would otherwise end up in a landfill. Our recycled cotton fibers are created from pre-consumer & post-consumer cotton textile waste, using mechanical recycling processes that avoid the use of harsh chemicals (5). All of our recycled cotton fabric is certified by Global Recycling Standards (GRS), one of the apparel industry’s leading standards for recycled materials (6).

REGENERATIVE COTTON
Regenerative cotton is grown using farming methods that are not only less harmful to the environment but actually benefit the environment by improving soil health and biodiversity. Regenerative farming practices promote greater carbon sequestration in crops than traditional farming methods and increase the capacity of the soil to store nutrients and retain water (7).

In the Spring of 2023, we launched our first partnership with Oshadi Collective. Oshadi Collective is an initiative that aims to revive the traditional regenerative farming & textile practices of India by supporting a regional collective of farmers, spinners, weavers, and dyers (8). Through this program, we are able to fund the growth and harvest of the regenerative-farmed cotton we use and connect with the farms growing our regenerative cotton (9).

We are signatories of Textile Exchange's 2025 Sustainable Cotton Challenge, which commits brands to ensure 100% of their cotton is from sustainable sources by 2025. Since 2015, sourcing environmentally preferred cotton has been part of our brand DNA, we have already transitioned to 100% sustainably sourced cotton and will continue to only use sustainable cotton in our collections.

LINEN
Found throughout our collections, linen is a sustainable fiber made from the flax plant. Flax is naturally pest resistant that requires less pesticides, water and energy to produce compared to cotton and polyester (11). Flax aids in sequestering carbon into the soil, which removes carbon dioxide from the atmosphere and is beneficial for improving soil health(12). Linen is a durable fabric that transitions easily from season to season, keeps the body cool and gets softer with each wash and wear.

HEMP
Considered to be one of the most environmentally friendly fibers, Hemp is naturally resistant to pests, requires relatively little water compared to other cellulose fibers, and grows quickly, reducing the need for pesticides and chemicals to produce high crop yields (13). It is also beneficial for removing carbon from the atmosphere and restoring soil health, its deep roots prevent soil erosion and return nutrients to the land making it ideal for crop rotation (14). Hemp is a durable fabric similar to linen in breathability and feel, it is long-lasting and will soften with each wash and wear.

Animal Fibers

WOOL
Wool is a natural fiber with added performance attributes such as temperature regulation, durability, and natural water repellency (15). Considered a circular product by nature, wool can be recycled or biodegraded easily. Animal welfare is extremely important to us, and therefore we only source mulesing-free wool from producers that follow humane and eco-friendly processes aligned with our animal welfare guidelines (16). Mulesing is a practice used to prevent the infection caused by blowflies, however, it harms the animal in the process. Read more about our commitment to Animal welfare in Our Guidelines.

Climate Beneficial™

All of our wool knitwear and wool accessories are made with Climate Beneficial ™ wool from Emigh ranch (17) in Northern California. Climate Beneficial™ Wool is a project within Fibershed’s Climate Beneficial Agriculture Program which was trademarked by scientists and community organizers who measure how fiber ecosystems can adapt to, and mitigate climate change (18). This program supports regional ranchers and farmers in implementing carbon farming practices and land stewardship efforts such as prescribed grazing, creation of pollinator habitat, freshwater creek restoration, and a host of 35 practices known to support healthy soils (19). These practices aid in sequestering carbon back into the soil and vegetation, which removes carbon dioxide in the atmosphere, enriches the soil, and helps to restore healthy ecosystems. With our partners, we are centering and uplifting nature-based solutions that are a critical contribution in the work to reverse climate change.
