Men's Swim Briefs

Measure your waist at the narrowest point and consult the brand's size chart; swim brief sizing varies by brand and may differ from regular underwear sizes. If between sizes, consider sizing up for more coverage or sizing down for a snug, performance-oriented fit

Common materials include nylon, polyester, and blends with elastane or spandex; polyester offers chlorine resistance and longevity, while nylon provides a smoother feel and quicker drying. Higher elastane content increases stretch and a snug fit but can degrade faster with chlorine exposure

Consider the cut (low-rise, mid-rise, high-rise) and the width of the waistband and front panel for comfort and intended activity; performance briefs often have a contoured pouch and secure waistband for support during swimming, while fashion-focused styles may prioritize minimal coverage

Rinse briefs in cold water immediately after use to remove chlorine, salt, and sunscreen, wash by hand or on a gentle cycle with mild detergent, and air dry flat away from direct sunlight to prevent fabric and elastic breakdown. Avoid bleach, fabric softeners, and high-heat drying

Frequent swimmers should prioritize chlorine-resistant fabrics (polyester or PBT blends), reinforced stitching, and a secure fit to maintain shape over time; occasional users can focus more on style, color, and comfort since wear from chlorine will be less frequent

Solid dark colors and classic patterns hide wear and fading better and are versatile for both training and casual beachwear; brighter colors and prints are fine for fashion but may show chlorine fading sooner unless made from fade-resistant fabrics

Swim briefs typically range from budget options under $30 to higher-quality pieces above $60; performance-oriented or brand-name briefs that use chlorine-resistant fabrics and stronger construction tend to be in the mid to higher end of that range
