Speedo Girl's Swimsuit One Piece Closed Racerback (Style 12WT)

In this review of the Speedo Girl's Swimsuit One Piece Closed Racerback, the bottom line is simple: this suit is built for swim practice and frequent pool use. The reviewer found it best for young swimmers who need a durable, performance-oriented suit that resists chlorine and sun damage. Constructed with recycled polyester and XLANCE two-way stretch, the suit balances fit and longevity, making it a sensible choice for lessons and competitive training where fabric that holds up to regular chlorine exposure matters.

Key Features

• Recycled fabric: The body is made in part from Repreve polyester yarn created from 100% post-consumer plastic, which reduces waste while maintaining fabric strength.
• Chlorine resistant: Ultra-chlorine-resistant construction helps the suit retain shape and color through repeated pool sessions.
• Block the Burn UPF 50+: Built-in sun protection lets swimmers train outdoors with reduced UV exposure on covered skin.
• Pilling resistant: The finish is designed to resist surface pilling, keeping the suit looking smoother with regular use.
• XLANCE two-way stretch: The fabric offers flexible, long-lasting performance fit that follows body movement for strokes and turns.

Who It's For

The Speedo one-piece is aimed at young athletes who attend regular swim lessons or compete at club level and need a suit that stands up to chlorine and frequent washing. Its racerback cut and two-way stretch suit swimmers who require freedom of movement and a close performance fit.

Parents shopping for recreational kids who prioritize fashion over function, or those needing a very forgiving, loose-fit suit, may prefer softer, leisure-focused styles. Also, shoppers who consistently find swimwear runs small should consider ordering a size up after checking fit notes.
