Sierra Bikini Bottom

This bikini bottom features a high-cut leg and a slim, minimalist silhouette that sits sharp against the hip. The cedar-toned fabric is punctuated by a single resin ring at the side, nodding to the tactile, artisanal hardware often found in 70s-inspired poolside gear. It is a lean, uncomplicated piece that relies on the contrast between the matte, saturated earth tone and the polished detail of the hardware.

Safety Rating: Lowest

Analysis: This garment is constructed from a blend of recycled polyamide and elastane, both of which are petroleum-based synthetic polymers. These plastic-derived fibers lack natural breathability and carry a high risk of microplastic shedding during laundering.
