How to Choose the Best Women’s Athletic One-Piece Swimsuits
Intended Use
Consider where and how you'll primarily use your swimsuit. For competitive swimming or intense training, look for suits designed with minimal drag and maximum flexibility. If your activities include open water swimming, you might prefer a suit with UV protection and perhaps a slightly more durable fabric. For recreational activities or water aerobics, comfort and ease of movement might be the top priorities. Different suits are engineered with specific performance benefits in mind, so match the suit’s features to your needs.
Frequently Asked Questions
What is the best material for an athletic swimsuit?
Polyester and nylon blends are generally considered best for athletic swimsuits due to their durability, stretch, and resistance to chlorine and saltwater. These materials offer a good balance of comfort and performance for regular training.
How should an athletic swimsuit fit?
An athletic swimsuit should fit snugly without being constricting, feeling like a second skin. It should allow for a full range of motion without any pulling, chafing, or gapping. Proper fit ensures comfort and reduces drag during water activities.
How do I care for my athletic swimsuit?
Always rinse your swimsuit in cold, fresh water after each use to remove chlorine and salt. Gently squeeze out excess water and air dry it away from direct sunlight. Avoid machine washing or drying to preserve the fabric's integrity.
What does 'chlorine-resistant' mean for swimwear?
Chlorine-resistant swimwear is made from fabrics, often polyester-based, that are specifically treated or woven to withstand the damaging effects of chlorine found in swimming pools. This helps the suit maintain its shape, color, and elasticity over time.
Are racerback swimsuits better for training?
Racerback designs are popular for training as they often provide excellent support and reduce shoulder strap slippage. They allow for a wide range of arm movement, which is beneficial for swimming strokes and other athletic activities.
Should I choose a suit with built-in support?
If you require extra support, especially for high-impact activities or if you have a larger bust, a suit with a built-in bra or shelf bra can significantly enhance comfort and reduce movement. This feature is common in athletic-specific designs.
