How to Choose the Best Girls’ Athletic Two-Piece Swimsuits
Key Features to Consider
- Fabric: Look for durable, chlorine-resistant fabrics like polyester or nylon blends. These materials hold their shape and color longer, even with frequent use in chlorinated pools. Quick-drying properties are also beneficial.
- Fit and Support: Ensure the suit offers a secure yet comfortable fit. The top should provide adequate support without digging in, and the bottoms should stay in place during active movements. Adjustable straps or drawstrings can enhance customization.
- Coverage: Athletic styles often prioritize function over excessive coverage. Consider the desired level of modesty for the wearer, looking at the cut of the bottoms (e.g., briefs, boy shorts) and the style of the top (e.g., tankini, halter, racerback).
- Durability and Construction: Flatlock seams help prevent chafing and are more durable. Reinforced stitching and high-quality elastic are indicators of a suit built to last through rigorous training.
Choosing the Right Style
- Racerback Tops: These offer excellent freedom of movement for the shoulders and are a popular choice for competitive swimmers.
- Tankini Tops: A tankini provides more coverage than a traditional bikini top and can be a good option for those seeking a balance between sportiness and modesty.
- Boy Short Bottoms: These offer more coverage and can feel more secure during active play or training compared to traditional bikini bottoms.
- Brief Bottoms: A classic choice, offering less coverage but maximum flexibility for swimming strokes.
Care and Maintenance
- Rinse the swimsuit in cold, fresh water immediately after each use to remove chlorine, salt, and sunscreen.
- Hand wash with mild soap if necessary, avoiding harsh detergents.
- Do not wring or twist the fabric; gently squeeze out excess water.
- Lay flat to dry away from direct sunlight, which can fade colors and degrade fabric.
Frequently Asked Questions
What makes a swimsuit suitable for athletic training?
Athletic swimsuits are typically made from durable, chlorine-resistant fabrics that offer a secure fit. They prioritize freedom of movement and often feature designs that stay in place during active swimming.
How should a girl's athletic swimsuit fit?
It should fit snugly without being uncomfortably tight. There should be no gaping or excessive digging from straps or waistbands. The suit should stay in place when moving.
What is the best fabric for an athletic swimsuit?
Polyester and nylon blends are generally preferred for their durability, chlorine resistance, and quick-drying properties. Spandex is often included for stretch and shape retention.
How do I clean an athletic swimsuit?
Rinse thoroughly with cold, fresh water after each use. Hand wash with mild soap if needed, and always air dry away from direct heat or sunlight.
Are tankini tops good for sports?
Yes, tankini tops can be suitable for sports, especially those with a racerback or supportive strap design. They offer more coverage while still allowing for good mobility.
What is the difference between boy short bottoms and brief bottoms?
Boy short bottoms provide more coverage, extending further down the leg, which can offer more security. Brief bottoms are more traditional, offering less coverage but maximum flexibility for swimming.
