How to Choose the Best Girls’ Athletic One-Piece Swimsuits
Fabric and Durability
Choosing a swimsuit made from high-quality, durable fabric is essential for active use. Look for materials like polyester or a polyester blend, which are known for their resistance to chlorine and UV rays. These fabrics also offer excellent shape retention, ensuring the suit maintains its fit over time, even with frequent washing and exposure to pool chemicals. Consider suits with UPF protection for added safety during outdoor training sessions.
Fit and Comfort
The fit of an athletic one-piece should be snug but not restrictive. It should allow for a full range of motion without riding up or causing discomfort. Key areas to check are the leg openings, which should be cut comfortably, and the shoulder straps, which should stay in place without digging in. Adjustable straps or a well-designed back closure can offer a more customized and secure fit.
Style and Support
Athletic one-pieces come in various styles, with different back designs and strap configurations. Racerback and crossback styles are popular for competitive swimming as they offer excellent support and freedom of movement for the shoulders. Some suits may also feature built-in shelf bras or compression panels for added support. Consider the specific demands of the sport and the swimmer's preference for coverage and support.
Sizing and Measurement
Proper sizing is paramount for a functional and comfortable swimsuit. It's recommended to consult the brand's specific size chart, as sizing can vary significantly between manufacturers. Measure your child's chest, waist, and hips accurately. Remember that athletic swimsuits are designed to fit snugly, so a size that feels tight initially may be the correct fit for swimming.
Frequently Asked Questions
How often should an athletic swimsuit be replaced?
The lifespan of an athletic swimsuit depends on usage and care. With regular use and proper washing, most durable suits last between 6 months to a year. Signs it's time for a replacement include loss of elasticity, fading, or thinning fabric.
Are compression swimsuits good for young athletes?
Compression swimsuits can offer benefits by improving hydrodynamics and muscle support. However, they should fit properly to avoid restricting movement. For younger athletes, comfort and freedom of movement are often prioritized over extreme compression.
What is the best way to care for an athletic swimsuit?
Always rinse your swimsuit with cool, fresh water immediately after use to remove chlorine and salt. Hand wash with mild detergent and lay flat to dry away from direct sunlight. Avoid using a washing machine or dryer, as these can damage the fabric and elastic.
How do I know if the swimsuit fits correctly?
A correctly fitting athletic swimsuit should feel snug and secure without pinching or chafing. There should be no excess fabric, and it should stay in place during swimming and training movements. The leg openings and straps should not dig into the skin.
What does UPF protection mean on a swimsuit?
UPF stands for Ultraviolet Protection Factor. A UPF rating indicates how well the fabric protects your skin from the sun's harmful ultraviolet rays. A higher UPF number means greater protection.
Should I buy a size up for my growing child?
It's generally best to buy the size that fits correctly now. Athletic swimsuits are designed to be snug, and buying too large can lead to discomfort and poor performance. Look for brands known for durability and consider purchasing a new size when needed.
