Byron Top

This bikini top features a structured, U-shaped underwire that creates a sharp, architectural neckline against the chest. The mint plaid fabric is a high-stretch nylon-elastane blend that clings closely to the body, emphasizing a clean, minimalist geometry. It leans into the brand’s penchant for body-conscious silhouettes, trading traditional swimwear softness for a precise, lingerie-inspired fit.

Safety Rating: Lowest

Analysis: This garment is constructed from a blend of nylon and elastane, both of which are petroleum-based synthetic polymers. These materials offer low breathability and pose concerns regarding microplastic shedding and potential chemical leaching during high-temperature or sweat-heavy wear.
