FAQs

Are these shorts suitable for intense swimming?

Yes, the integrated brief liner and stretch fabric make them suitable for both recreational swimming and more active water sports.

Does the fabric have UV protection?

While the material is high-quality polyester, it is primarily designed for comfort and drying. Always apply sunscreen to exposed skin.

How should I store these shorts for the winter?

Ensure they are completely dry before storing in a cool, dry place away from direct sunlight to preserve the color and elastic.

Can I use these for running?

Because of the quick-dry material and built-in liner, they can function as basic athletic shorts for short runs or gym sessions.

Are the pockets deep enough for a smartphone?

The pockets are intended for lightweight items; it is not recommended to keep electronic devices in them, especially near water.

What does bluesign® certified mean?

It means the product was manufactured with high environmental and safety standards, minimizing the impact on people and the planet.

Troubleshooting

Fabric feels heavy or retains water

Ensure the shorts are fully wrung out after swimming. The quick-dry technology works best when excess water is removed.

Drawstring slips during activity

Tie a secure double knot to prevent the drawstring from loosening during intense movement or diving.

Liner feels uncomfortable

Ensure the shorts are pulled up correctly to allow the liner to sit naturally against the skin.

Setup, Compatibility & Care

These swim shorts are designed for immediate wear; simply adjust the drawstring for your preferred waist security. To maintain the integrity of the fabric and the elastic properties of the waistband, follow these care instructions carefully:

  • Washing: Machine wash in warm water at 40° C using a gentle cycle.
  • Bleaching: Do not use bleach, as it may degrade the synthetic fibers.
  • Drying: Tumble dry only on low heat to prevent heat damage to the elastic components.
  • Maintenance: Do not iron or dry clean, as these processes can melt the polyester material or alter the fit.
