How to Choose the Best Men’s Athletic Swimwear
Materials and Durability
The fabric composition of athletic swimwear is paramount for its longevity and performance. Look for materials like polyester, PBT (polybutylene terephthalate), or blends containing these. Polyester is highly resistant to chlorine and fading, making it an excellent choice for frequent pool use. PBT offers similar chlorine resistance with good stretch and shape retention, often feeling softer than pure polyester. Spandex or Lycra blends provide elasticity and comfort but are generally less chlorine-resistant, so they are often mixed with more durable fibers to balance stretch with longevity. A higher percentage of chlorine-resistant material ensures the garment withstands repeated exposure without breaking down or losing its shape.
Fit and Style
Athletic swimwear comes in various styles, each offering different levels of coverage and freedom of movement. Briefs provide minimal coverage and maximum leg mobility, often preferred by competitive swimmers for reduced drag. Jammers, extending to just above the knee, offer more coverage and muscle compression, which can aid in reducing fatigue. Trunks are a versatile option, sitting mid-thigh, offering a balance of comfort and coverage for both training and leisure. Board shorts, while popular for casual beachwear, are generally not ideal for serious athletic training due to their looser fit and potential for drag. Ensure the fit is snug but not restrictive, allowing for a full range of motion without chafing.
Features for Performance
Several design elements contribute to the performance of men’s athletic swimwear. Look for features like:
- Flatlock seams: Minimize chafing and irritation during extended wear.
- Adjustable drawstring waist: Essential for a secure fit, preventing slippage during dives or turns.
- Built-in liners: Provide added support and modesty.
- UV protection: Valuable for outdoor swimming, helping to shield skin from harmful sun rays.
- Quick-drying properties: Beneficial for comfort both in and out of the water.
Care and Maintenance
Proper care significantly extends the life of your athletic swimwear. Always rinse your garment thoroughly with cool, clean water immediately after each use to remove chlorine, salt, and body oils. Avoid wringing it out vigorously, as this can damage the fabric fibers. It's best to hand wash with a mild soap and cold water, then lay flat or hang dry in the shade. Direct sunlight and high heat from dryers can degrade elastic fibers and cause colors to fade prematurely. Never use bleach or harsh detergents, as these will severely reduce the fabric's lifespan.
