Follow our care instructions to properly care for your organic trunks

To make your trunks last longer, wash them thoroughly after each use, that way removing any salt/chlorine residue.

We recommend washing the swim trunks with similar color clothing and not wringing the garment.

At Lane Line Threads, we take care of your gear—and the planet it depends on.

Every order is thoughtfully packed to arrive safely and sustainably, using the most eco-friendly materials available in each region.

For our North American swimmers, we’ve made the switch to poly mailers made with 90–100% post-consumer recycled (PCR) plastic.

Single-item orders are shipped directly in the mailer, while multi-item orders include an inner protective bag for added care.

In Australia, we proudly ship using compostable eco-mailers.

For Japan and China, we currently use standard mailers while we continue searching for greener local solutions.

Our goal is simple: reduce environmental impact while keeping your gear secure and ready for action.

Because sustainability doesn’t stop at the pool’s edge—it’s in every detail, right down to the packaging.

Soft on skin, strong in water

What is recycled polyester?

Recycled polyester (aka rPET) is basically magic in fabric form. It’s made by giving new life to materials like plastic bottles and packaging, turning them into soft, durable fibers.

And the best part?

It performs just like regular polyester—quick-drying, comfy, and ready for action—while being a smarter, more sustainable choice for your swim gear.

Wear your passion, protect your planet

How’s recycled polyester made?

Recycled polyester starts its journey as old plastic bottles and packaging. First, they’re crushed into tiny chips, then spun into yarn, turned into soft fibers, and finally woven into the fabric that makes up your favorite swim gear.

Made for laps, laughs, and saving the ocean

What are the advantages of recycled polyester?

Making rPET is way easier on the planet—it uses 33–53% less energy and gives off about 55% fewer CO₂ emissions compared to new polyester.

Plus, by turning old plastics into gear like our Swim Trunks, we help keep waste out of landfills and out of the water we love to swim in.

Let’s complete your look!

Why Recycled Polyester Costs More—And Why It’s Worth It.

We knew you’d ask.

At Lane Line Threads, we believe in transparency, and we want to share the "why" behind our prices.

It’s a story of sustainability, innovation, and a whole lot of heart—yours and ours.

From plastic bottles to beach vibes—because the ocean doesn’t need more junk

The Hunt for Plastic Waste

First, we have to collect the plastic.

This isn't your average recycling bin pickup; it often involves dedicated efforts to gather plastic from oceans, coastlines, and landfills.

This crucial first step helps clean up our planet, but it also has a price tag.

the only time trash makes you look this good

A High-Tech Transformation

Those plastic bottles don't magically become thread.

They go through a multi-stage process of sorting, cleaning, chipping, and melting.

This advanced technology is designed to turn waste into a high-quality, wearable fabric, and it's far more specialized and costly than traditional textile manufacturing.

Your drop in the bucket

Small Batches, Big Impact

Unlike fast fashion giants that produce millions of identical items, we operate on a smaller scale.

This allows us to ensure quality and ethical production, but it also means we don't benefit from the massive economies of scale that drive down prices in the conventional clothing industry.

Your Purchase is a Pledge, Not Just a Purchase

When you choose a Lane Line Threads product, you’re not just buying a piece of clothing.

You are making a powerful statement.

You are saying "yes" to a cleaner planet and "no" to wasteful practices.

The extra cost isn't just a number; it's the investment in:

  • Pioneering a new way: We're helping to build a more sustainable future for the fashion industry.

  • Ethical production: We ensure fair wages and safe working conditions for everyone involved in our supply chain.

  • The planet's well-being: A portion of every purchase goes directly to ocean cleanup initiatives.

So, the next time you see a price difference, we hope you’ll see the bigger picture.

You're not just buying a swim trunks; you’re helping to pull a piece of plastic out of our oceans and weaving it into a brighter future.

Join the movement. Wear the change. Because saving the planet should be in style.

Frequently Asked Questions

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.
