Swimm Organic Merino Wool Swimwear 

🌿Swimm Organic Merino Wool Swimwear. I am so excited that I found this new organic bathing suit brand while searching for plastic-free swimwear. I reached out to the owner; she told me on May 11, 2026: “I pioneered modern wool swimwear in 2018. ” Amazing!!

The best swimwear are made with plastic-free, natural fabric, biodegradable materials with increased the durability of the textiles, to cut the microplastic pollution.

🍃Responsible swimwear brands choose sustainable, non-toxic, and better materials. They use recycled materials instead of making new ones. They use available resources while cleaning the oceans. They use sustainable materials and practices such as:

 

✅ Responsible Wool Standard (RWS) Certified: Prohibits cruel practices like mulesing; Animal Welfare Standards: It enforces strict standards based on the Five Freedoms of animal welfare. Land Management: It requires farms to practice progressive soil management, biodiversity protection, and native species conservation.

✅ OEKO-TEX®Certified: certified to meet the global Oeko-Tex standard for safe textiles. OEKO‑TEX®‑certified swimwear means the fabric has been independently tested and verified to be free from a long list of harmful substances (such as heavy metals, formaldehyde, carcinogenic dyes, and allergenic colorants), making it safer for skin contact and environmental health.
