Lobster print swim trunks materials

Our swim trunks put sun protection first. Sun-safe fabric blocks 98% of UVA and UVB rays so you can enjoy the outdoors longer.

• We made these from the highest-rated, most comfortable UPF 50+ sun-protective fabric.

• 4-way stretch fabric provides extra freedom of movement.

• Our chlorine-resistant and quick-dry stretch fabric stands up to pool chemicals and dries fast after swim time.

• The flat seams minimize skin irritation and rubbing for all-day comfort.

• We use a polyester and spandex blend for durability and stretch.

• The trunk fabric differs slightly from other collection items, so colors might not match exactly due to fabric composition differences.

How to care for your lobster print swim trunks

Rinse your lobster swim trunks in fresh water immediately after each swim to remove chlorine, salt, or sand. For a deeper clean, wash them in cold water with mild soap, either by hand or on your washing machine's gentle cycle. Avoid harsh detergents that break down the UPF protection and fabric elasticity.

After washing, squeeze out excess water without wringing or twisting the fabric. Lay your trunks flat to air dry in a shaded area, as direct sunlight fades the vibrant lobster print and damages the sun-protective properties. Never use a clothes dryer, as heat ruins the stretch and shortens the lifespan of your swimwear.
