Key Features to Look for in Open Water Swimming Suits

Material Durability and Salt/Chlorine Resistance

Open water swimming demands suits with exceptional durability against harsh elements. Look for suits made from chlorine-resistant fabrics like PBT (polybutylene terephthalate) or nylon-lycra blends that withstand salt water exposure. Premium suits feature UV-resistant materials that prevent degradation from sun exposure, extending their lifespan by 30-40% compared to regular swimwear. Reinforced seams with flatlock stitching further enhance durability in challenging open water conditions.

Visibility and Safety Elements

Safety should be your top priority when selecting an open water swimming suit. Choose suits with high-visibility colors like neon yellow, orange, or pink that remain visible from distances exceeding 500 yards. Many performance suits incorporate reflective elements or patterns on shoulders and backs to enhance visibility in low-light conditions. Some advanced models feature built-in attachment points for safety buoys or whistles, providing critical emergency signaling capabilities when swimming in remote locations.

Comfort During Extended Wear

Extended open water sessions require suits that prevent chafing and irritation. Look for suits with minimal or flat-locked seams positioned away from sensitive areas like underarms and neck. Silicone-lined edges around leg openings and necklines prevent uncomfortable riding up during long swims. The ideal fit should feel snug but not restrictive, with specific attention to shoulder mobility for freestyle stroke mechanics. Premium suits offer graduated compression that reduces muscle fatigue during sessions exceeding 60 minutes.

How to Choose the Right Open Water Swimming Suit for Your Needs

Determining the Best Fit for Your Body Type

Finding the perfect fit starts with understanding your unique body proportions. Torso length, shoulder width, and hip-to-waist ratio drastically affect how a suit performs in open water. Try on multiple sizes—a suit should feel snug without restricting breathing or shoulder movement. Women with longer torsos benefit from suits with adjustable shoulder straps, while men with broader chests should look for suits with extra stretch across the pectorals.

Balancing Budget with Performance Requirements

You don’t always need the most expensive suit to achieve great performance. Entry-level open water suits ($50-$100) offer adequate durability for recreational swimmers training 1-2 times weekly. Mid-range options ($100-$250) provide better hydrodynamics and longevity for regular trainers. Reserve premium suits ($250+) for competitive events or if swimming 4+ times weekly—their advanced features justify the cost only with frequent use.

Matching Suit Specifications to Water Conditions

Water temperature should dictate your suit thickness and coverage. For warm waters (75°F+), choose thin, minimal coverage suits with UPF protection. Moderate temperatures (65-75°F) require medium-thickness suits with strategic paneling. Cold water (below 65°F) demands neoprene suits with thickness between 2-5mm—thicker in the core and thinner in the limbs for movement. Always factor in wind chill and air temperature when making your final selection.

Maintaining Your Open Water Swimming Suit for Longevity

Proper Cleaning and Storage Techniques

Rinse your swimsuit immediately after each use with cold freshwater to remove chlorine, salt, and bacteria. Skip the washing machine and instead hand wash with mild detergent specifically designed for performance fabrics. Always air dry your suit flat in the shade—never wring it out or use a dryer. Store your clean, dry suit in a breathable mesh bag away from direct sunlight to prevent color fading and fabric deterioration.

Addressing Wear and Tear Issues

Inspect your suit regularly for signs of thinning fabric, especially in high-friction areas like under the arms and inner thighs. Small tears can be reinforced with specialized swimwear thread before they expand. For pilling, gently use a fabric shaver to remove bobbles without damaging the material. Elasticity issues around leg openings and waistbands indicate the suit’s compression properties are diminishing—alternate between two suits during training periods to extend their life.

When It’s Time to Replace Your Suit

Replace your open water swimming suit when the fabric becomes transparent or develops a perpetual sheen. Performance deterioration—such as increased drag or water absorption—signals it’s time for a new suit even if visible damage isn’t apparent. Most quality open water suits maintain optimal performance for 60-80 hours of swim time, though competitive suits may need replacement sooner. If you’re experiencing consistent chafing despite proper fit, the material has likely broken down beyond repair.

Conclusion: Maximizing Your Open Water Swimming Experience with the Right Gear
