01Overview

The Vitamin A EcoLux Luna Bottom is a low-rise bikini bottom crafted from the brand's signature EcoLux fabric, a premium regenerated nylon blend made from recycled ocean plastics and reclaimed fishing nets. This sustainable textile delivers a silky, second-skin feel against the body while offering four-way stretch that moves naturally with every dive, paddle, or lounge session on the sand. The Luna colorway brings a soft, moonlit neutral tone to the piece, versatile enough to pair effortlessly with nearly any top in your swim rotation, from simple triangle styles to structured bandeau silhouettes, making it a foundational piece for building out a beach-ready wardrobe.

Designed with a cheeky coverage cut and slim side straps, the Luna Bottom flatters the hip and leg line without sacrificing comfort or confidence, striking a balance between minimal coverage and everyday wearability. The waistband sits comfortably at the natural hip, avoiding digging or rolling during active movement, whether you're swimming laps, playing beach volleyball, or simply walking along the shoreline. Flatlock stitching along the seams reduces chafing and adds a clean, polished finish that holds its shape wash after wash, so the bottom retains its structure and color vibrancy even with repeated exposure to saltwater, chlorine, and sun.

Beyond its wearable design, the EcoLux Luna Bottom reflects Vitamin A's ongoing commitment to responsible swimwear production, proving that eco-conscious materials can still deliver a flattering, fashion-forward fit. It layers beautifully under cover-ups and sarongs for a boardwalk stroll, yet holds its own as a standalone statement piece on the sand or by the pool. Whether you're restocking your warm-weather essentials or searching for a reliable, sustainably made bikini bottom that transitions from resort mornings to sunset swims, the Luna Bottom offers a dependable, elevated option rooted in both style and environmental mindfulness.
