Collection: Swim Trunks

Know Your Waist Size Measure your waist at the narrowest point (above your hips, below your ribs). Check the brand’s sizing chart. Tip: If you’re between sizes, size up for comfort, especially if the trunks have no stretch. Consider the Rise Rise = distance from the crotch seam to the waistband. Low-rise: sits below the hips (trendy, less coverage). Mid-rise: sits at the natural waist (classic, comfortable). High-rise: sits above the waist (rare in men’s trunks). Check the Length Shorts-style (5–7” inseam): classic mid-thigh length, good for swimming and casual wear. Boardshorts (9–11” inseam): longer, sit at the knee, better for surfing or active movement. Briefs / Trunks (2–4” inseam): minimal coverage, fast-drying, great for lap swimming. Liner & Support Mesh liner: provides support and prevents chafing. Compression brief: adds snug support for lap swimming or sports. No liner: sometimes used in fashion-focused trunks; may feel freer but less supportive. Adjustable Waist Drawstrings: allow fine-tuning and are good for active use. Elastic waistbands: convenient, may not be as secure for vigorous swimming. Check Brand-Specific Sizing Always consult the brand’s sizing chart because measurements vary. Some brands give waist and hip measurements, which are more accurate than “S/M/L.” 💡 Quick Tip: For eco-friendly trunks like Lane Line Threads Swim Trunks, sizing tends to run true to standard men’s sizes, but double-check waist measurements if you plan to swim vigorously.

Average Lifespan Everyday swim trunks: 1–3 years with regular swimming in pools or the ocean. High-quality or eco-friendly trunks like Lane Line Threads: 3–5 years if well cared for. Factors That Affect Longevity Chlorine Exposure Chlorine weakens fabric fibers over time. Rinse trunks immediately after swimming in a pool. Saltwater & Sand Salt can dry out fibers; sand can cause pilling. Rinse trunks in fresh water after ocean swimming. Sun & Heat UV rays and high heat can fade colors and weaken elasticity. Avoid leaving wet trunks in direct sunlight for hours. Fabric Type Polyester or recycled polyester: durable, holds color and shape longer. Nylon: soft and lightweight but less resistant to chlorine and UV. Spandex/Elastane content: gives stretch but degrades faster, especially in hot pools or frequent swimming. Care & Washing Hand-wash or machine wash on cold; avoid bleach and harsh detergents. Don’t tumble dry; air-dry flat or hang to prevent stretching. Signs It’s Time to Replace Swim Trunks Elastic waist or drawstring has lost tension. Lining or fabric is thinning, tearing, or pilling. Color fading or bleaching, especially in UV areas. Fit has become loose or uncomfortable in water. 💡 Pro Tip: Rotating two or three pairs of swim trunks extends their life. That way, each pair dries and recovers fully between uses.

Our swim trunks come with a built-in mesh liner for comfort and support—no extra layer needed. Want more support? Slip on swim briefs, jammers, or compression shorts. Your call, your comfort.

Picking the right fit comes down to your body and what feels good in the water: Athletic build: Go for snug trunks that show off your hard work. Slim build: Mid-length trunks add a little extra presence and balance. Stocky build: Skip the super tight stuff - relaxed trunks keep you comfy and confident.
