Salty Girl Swim – Regenerative Ocean Advocates

Salty Girl Swim goes beyond recycled materials with their regenerative ocean philosophy.

Amazon's verified reviews highlight Lava Swim's "exceptional craftsmanship" and "comfortable fit."

Sustainable Sizing – Inclusive Eco-Fashion

Several underrated brands on Amazon are leading the charge in inclusive sustainable swimwear. Brands like Reformation Swim and Summersalt offer extended sizing (XXS-4X) using recycled materials without compromising on eco-standards. Amazon buyers praise their "true-to-size accuracy" and "flattering designs for all body types." What makes these brands stand out is their zero-waste pattern engineering, which creates multiple sizes from the same fabric layout, reducing textile waste by 25%. They use recycled elastane that maintains shape and support across sizes, addressing a common pain point with sustainable swimwear. These brands also feature diverse models in their Amazon listings, promoting body positivity alongside environmental responsibility. At $50-$70 range, they offer inclusive sizing without the typical "inclusive sizing premium" seen in fast fashion. Their commitment to both people and planet makes them hidden gems in Amazon's sustainable fashion marketplace.

Care and Longevity – Maximizing Your Sustainable Investment

To maximize the lifespan of recycled swimwear, proper care is essential. Unlike conventional swimwear, recycled fabrics like ECONYL® and REPREVE® require gentle handling to maintain their integrity. Amazon's top reviewers recommend rinsing in cold water immediately after use to remove chlorine and salt that degrade fibers. Avoid wringing—instead, gently press out excess water. For washing, use a mesh laundry bag and eco-friendly detergent on a delicate cycle. Never dry in direct sunlight, as UV rays break down recycled elastane faster. Air-dry flat to maintain shape. Following these practices can extend your swimwear's life by 2-3 seasons, reducing the need for replacements. Brands like Swellr and Salty Girl offer repair services for minor damages, further extending product life. By caring for your sustainable swimwear properly, you maximize both your investment and environmental impact.
