Goodfellow & Co Men’s 5″ Swim Trunks
Our 5″ swim trunks are built for guys who want one pair that works everywhere—pool, beach, backyard barbecue. The inseam hits mid-thigh for mobility without riding up, and the quick-dry fabric means you’re not sitting wet through dinner. We use a lightweight woven polyester blend that sheds water fast and resists fading even after dozens of washes.
The elastic waistband with drawcord gives you a secure, adjustable fit, and the built-in mesh brief eliminates the need for separate swim briefs. Two side pockets and one back pocket with a drainage grommet keep your essentials close without waterlogging. These trunks transition from swim to casual wear in minutes, so you can spend less time changing and more time enjoying your day.
Built for water and beyond
Fabric & Construction Details
We engineered these Goodfellow & Co men’s 5” swim trunks with 100% polyester woven fabric that dries in under 30 minutes after a swim. The material is treated with a durable water repellent (DWR) finish that beads moisture off the surface, so you’re not walking around soaked. UPF 50+ sun protection is built into the weave, blocking 98% of UV rays during long beach days.
The mesh brief liner is sewn from soft polyester mesh that won’t chafe or bunch. Flatlock seams throughout reduce irritation during active wear, whether you’re swimming laps or playing volleyball. We reinforce the waistband with double-stitched construction and use rust-resistant metal grommets on the back pocket to prevent corrosion from saltwater.
Sizing & Fit Guide
Our 5″ inseam falls mid-thigh on most builds, offering coverage without restricting your stride. The elastic waistband stretches to accommodate natural movement, and the drawcord lets you dial in the exact fit you need. We recommend ordering your usual pant size—these trunks run true to size with a relaxed fit through the hip and thigh.
Size Chart
Small fits waist 28-30″, Medium fits 32-34″, Large fits 36-38″, XL fits 40-42″, and XXL fits 44-46″. The rise sits comfortably at the natural waist. If you’re between sizes or prefer a snugger fit for water sports, size down; for a looser, board-short feel, size up.
Pocket Design & Functionality
Each pair features two deep side pockets with mesh drainage panels, so water doesn’t pool when you climb out of the pool. The pockets are sized to hold a phone, wallet, or keys securely—we’ve sewn them 7 inches deep with reinforced bar tacks at stress points. The back pocket includes a hook-and-loop closure flap and a centered drainage grommet, perfect for storing a room key or ID card you want to keep dry.
We skipped metal zippers in favor of durable hook-and-loop closures, eliminating the risk of rust and broken pulls. The same quick-dry fabric lines the pocket interiors, so even if you jump in with your phone in a waterproof case, the pockets won’t stay damp for long.

Machine wash cold with like colors and tumble dry on low. Avoid fabric softener, as it can reduce the effectiveness of the DWR finish over time. Rinse the trunks in fresh water after exposure to chlorine or saltwater, and hang dry in the shade to preserve the finish and color. If beading performance weakens after many washes, you can reapply a spray-on water repellent to restore it.
