Full details

The Helly Hansen Cascais Trunk 4.5" is a versatile, performance-oriented swim short designed for active men who prioritize comfort during water sports, sailing, or beach relaxation. Featuring a lightweight, quick-drying fabric with added stretch and an integrated liner, these shorts offer excellent mobility and all-day wearability. One caveat to keep in mind is the 4.5-inch inseam, which provides a shorter, more athletic cut that may not suit those who prefer longer boardshorts.

FAQs

Are these trunks suitable for long-distance swimming?

Yes, the integrated liner and stretch fabric are designed to provide comfort and prevent chafing during active swimming sessions.

What does bluesign® certified mean?

It means the textile production process meets high standards for environmental impact, worker safety, and resource efficiency.

Can I wear these as casual shorts?

The stylish design and pockets make them appropriate for casual settings near the beach or pool, though the 4.5-inch length is quite short.

How should I store them when not in use?

Store them in a cool, dry place. Ensure they are completely dry before folding to prevent odors or mold.

Do the hand pockets have zippers?

No, the hand pockets are standard open-style pockets intended for quick access.

Is the fabric prone to fading?

While high-quality, we recommend avoiding prolonged exposure to direct, harsh UV rays and always rinsing them after saltwater use to protect the color.

Troubleshooting

Drawstring feels loose or slippery

Tie a double knot in the drawstring after tightening to ensure it remains secure during heavy waves.

Fabric holds onto sand

Once dry, shake the shorts vigorously or use a soft-bristled brush to remove trapped sand particles from the weave.

Setup, Compatibility & Care

To ensure the longevity of your Cascais Trunks, rinse them thoroughly with fresh water after every use in salt or chlorinated water to prevent fabric degradation. When cleaning, machine wash on a gentle cycle with similar colors. Avoid using fabric softeners, as they can break down the technical properties of the quick-dry fabric. Hang dry in a shaded area away from direct sunlight to maintain the integrity of the elastic waistband and the vibrancy of the printed graphics. No special setup is required; simply adjust the drawstring for your preferred tension before heading out.
