Understanding the Sustainable Fabric Composition of Our Period Swimsuits

Our eco-conscious period swimsuits are carefully engineered to combine comfort, protection and environmental responsibility. Each layer serves a distinct purpose:

• Lining (100% Organic Cotton): The inner fabric is comprised entirely of certified organic cotton, which is grown without harmful pesticides or synthetic fertilisers. Organic cotton is breathable, hypoallergenic and gentle on sensitive skin, reducing irritation and supporting healthy skin flora during your menstrual swim.
• Middle Layer (100% Rayon Fibre, Breathable TPU): Sandwiched between the lining and outer shell, this innovative core features 100% rayon fibre bonded to a breathable TPU (thermoplastic polyurethane) membrane. Rayon wicks moisture away from the body, while the TPU barrier offers reliable leak-proof protection without trapping odours. Together, they create a lightweight, quick-dry layer that locks in fluid—equivalent to up to two tampon’s worth—so you can swim confidently on light to moderate flow days.
• Outer Layer (78% Nylon, 22% Spandex): The exterior is crafted from a resilient blend of nylon and spandex. This combination ensures excellent stretch, shape retention and a sleek silhouette. Nylon is prized for its durability, while spandex adds the necessary flexibility for effortless movement. The long-lasting nature of this fabric blend means fewer replacements over time, lowering textile waste and carbon emissions compared to disposable swimwear.

Why This Composition Is Truly Sustainable

1. Organic Cotton Lining Reduces Chemical Use: Conventional cotton farming consumes vast quantities of water and relies heavily on pesticides. By choosing organic cotton, we support water conservation, healthier soil and reduced chemical runoff—key factors in sustainable textile production.
2. Breathable TPU Core Minimises Single-Use Products: The leak-proof TPU membrane allows the swimsuit to replace numerous single-use pads or tampons over its lifespan. Reusable period swimwear cuts down on plastic waste, packaging and sanitary disposal, offering an eco-friendly alternative that aligns with zero-waste principles.
3. Durable Outer Layer Extends Product Life: The nylon/spandex blend resists fading, pilling and loss of elasticity, ensuring that your swimsuit maintains its protective properties and flattering fit season after season. Longevity means fewer garments end up in landfill, and it reduces the environmental footprint associated with frequent replacements.

By combining an organic cotton lining, a breathable TPU core and a nylon/spandex outer shell, our period swimsuits offer a trifecta of comfort, performance and sustainability. Enjoy leak-proof protection, optimum hygienic benefits and a reduced environmental impact—all in one stylish piece of eco-friendly swimwear.
