The Ultimate Guide to Ethical and Sustainable Swimwear

Swimwear made out of hemp? Yes please. For decades, swimsuits have been made out of polyester, which is non-biodegradable and bad for the skin. Natasha Tonic’s hemp swimwear fabric is based around a unique, natural hemp fibre that is antimicrobial, UV resistant, durable, and a healthier choice for your skin and our oceans. Even better, each piece is slightly different since they're printed by hand, allowing for each sustainable bikini to be tailored for the most gorgeous you! Find sizes XS-XL.
