Stylish Nylon Swimming Trunks for Youth – Sapphire Blue, Lake Blue & Bold Colors

Feel the freedom of summer with vibrant, lightweight swimwear designed for young adventurers.

When Youth Meets the Waves: How Swim Trunks Define Summer Attitude

Picture this: golden sunlight glinting off turquoise water, laughter echoing across the shore, and a group of teenagers diving into the cool embrace of the ocean. In moments like these, every movement is a celebration — of friendship, of freedom, and of being unapologetically young. But what you wear in those moments matters more than ever. It’s not just about staying dry or comfortable; it’s about expressing who you are. This season, Polis introduces a fresh wave of youth swimwear that turns heads and stirs confidence — our new nylon swimming trunks in sapphire blue, lake blue, fiery red, and radiant yellow. These aren’t just swim shorts; they’re a statement. A splash of personality against the endless horizon.

Light as a Breeze, Free as You Are: The Comfort Science Behind Nylon Fabric

Ever worn a cotton swimsuit that clings uncomfortably after one dip? That heavy, soggy feeling is a thing of the past. Crafted from high-density nylon, these trunks offer a featherlight feel the moment you put them on. The tightly woven fabric ensures superior breathability while resisting water absorption, meaning faster drying times and less drag in the water. Unlike traditional materials, nylon holds up beautifully against chlorine, salt, and UV exposure — no fading, no stretching out. Whether you're training laps at dawn or catching waves at noon, the material moves with you, never against you. It's engineered for endurance, designed for energy.

Premium nylon construction ensures durability, softness, and rapid drying — ideal for active teens.

A Symphony of Blues — From Tranquil Lake to Dazzling Sapphire

Color isn’t just decoration; it’s emotion made visible. Take the serene lake blue — a hue that mirrors early morning mist over calm waters, evoking peace and clarity. Then there’s the deep, electrifying sapphire blue, reminiscent of tropical seas under midday sun, radiating confidence and depth. But we didn’t stop at blue. For those who live louder, we offer bold red — passionate, energetic, impossible to ignore — and sunny yellow, bursting with optimism and playfulness. Each shade speaks to a different side of youth: introspective, adventurous, fearless, joyful. And thanks to advanced dye technology, these colors stay vivid wash after wash, just like your memories of summer.

The Perfect Fit for Movement and Style: Loose Boxer Cut Redefined

Finding swimwear that looks good both in and out of the water can be a challenge. That’s why we designed these trunks with a relaxed boxer silhouette — roomy enough for full-motion activities like diving, jumping, and sprinting down the beach, yet clean-cut enough to pair effortlessly with a tee or hoodie. An elastic waistband with an adjustable drawstring ensures a secure, personalized fit for all body types. Inside, a soft mesh lining provides support without chafing, so comfort lasts from sunrise swim practice to sunset hangouts. This is swimwear built for real life — dynamic, unpredictable, and always in motion.

From sports to street style, these trunks transition seamlessly across adventures.

More Than a Swim Trunk: One Piece, Endless Roles

Imagine slipping into your sapphire blue trunks for an early swim class, then throwing on a linen shirt and sandals to grab iced coffee by the pier. Later, you’re lounging at a rooftop party, your bright yellow pair now doubling as standout casual shorts. That’s the versatility we designed into every pair. No longer confined to locker rooms and pool decks, today’s swimwear blurs the line between function and fashion. These trunks are light enough to pack for travel, stylish enough for urban outings, and tough enough for daily wear. They’re not just for swimming — they’re for living.

Youth Was Made for Full Color

This summer, don’t blend in. Stand out. Choose a color that matches your mood, your moment, your mindset. Whether you’re drawn to the quiet strength of lake blue or the unstoppable energy of red, these swim trunks are more than clothing — they’re a declaration. A reminder that growing up doesn’t mean toning down. At Polis, we believe style should be fearless, fabric should be functional, and every day should feel like a new adventure. So go ahead — dive in, hang out, turn heads. The water’s fine, but the view from the shore? Even better.
