Product Insights & Style Tips

The Onia Solid Charles 5" Swim Trunk carries that refined resort vibe, a clean cut anchored in classic tailoring. Built from quick-dry fabric, it feels crisp straight from the pool to the boardwalk, with a polished silhouette that stays put rather than clinging. The look is elevated by a streamlined waistband and a neat action-ready finish that says you’ve got style, even when the sun is high.

The fit reads true to size with a regular cut through the seat and leg, and a pull-on elastic waist thanks to a practical drawcord. Inside, a superfine mesh liner keeps you comfortable, while reinforced side pockets and a zipped back pocket add small but essential function for days spent near water. The 5 inch inseam hits at a versatile length for easy wear with sandals or sneakers, and the overall construction leans into a laid-back, refined vibe that travels well from beach to cafe.

Onia continues to blend heritage swim tailoring with modern, easy care needs, aligning with a clean, timeless menswear-inspired approach to resort wear. This trunk pairs effortlessly with a simple shirt or a breezy linen tee, offering a polished yet relaxed option for warm-weather getaways and poolside hangs alike.
