O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Stretch Fit 239

Our review of the O'NEILL Men's 21 in Solid Boardshorts finds them best for men who want a below-the-knee swim short that balances movement, quick drying, and useful storage. These boardshorts stand out because of the Hyperfreak stretch fabric that moves in all directions and the Hyperdry treatment that reduces damp time, making them a practical pick for surf sessions, pool days, or travel. The 21 in outseam gives a contemporary length that sits just below the knee for most wearers, and the built-in gusset and drawstring keep the fit secure without restricting motion.

Key Features

• 21 in outseam: Provides a below-the-knee fit that many testers found comfortable for both swimming and casual wear.
• Hyperfreak stretch: Fabric stretches in every direction so the shorts move with you during paddling, beach volleyball, or walking.
• Hyperdry quick dry: DWR treatment and fabric composition lead to faster drying after leaving the water, reducing cling and chill.
• Anti-rash Hyperthread: Smooth construction and fabric reduce chafing during extended activity against surfboards or sand.
• Side zip pocket: Secure storage for small essentials so keys or cards stay safe while active.
• Velcro fly with gusset: Drawstring and spandex fly gusset deliver an adjustable fit and improved comfort.

Who It's For

The O'NEILL 21 in boardshorts are aimed at men who want performance-forward swim trunks with a modern silhouette; they work well for surfers, swimmers and casual beachgoers who prioritize stretch and quick dry performance. The smooth fabric and anti-rash construction make them a sensible choice for anyone planning long days in and out of the water.

Those who prefer shorts with a full mesh liner or a notably shorter cut should look elsewhere, and shoppers who consistently wear nonstandard sizes should check fit guidance because customer feedback on sizing is mixed; some find them true to size while others report a roomier fit.
