O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Comfort 217

Our review of the O'NEILL Men's 21 in Solid Boardshorts finds them best suited for men who want a below-the-knee swim short that moves with them and dries fast. The single biggest reason to buy is the combination of Hyperfreak stretch and Hyperdry quick-dry treatment, which together deliver unrestricted motion and minimal post-swim dampness. The shorts strike a balance between surf-ready performance and everyday beachwear, and the feel and construction make them a practical choice for active days on the water.

Key Features

• 21 in Outseam: The below-the-knee length provides modest coverage while still allowing full leg movement for paddling or casual wear.
• Hyperfreak Stretch: The stretch fabric moves in all directions with the body, reducing resistance during surf or shore activities.
• Hyperdry Technology: Durable water repellent and quick-dry finish cuts drying time after exiting the water so the shorts are comfortable sooner.
• Anti-Rash Hyperthread: Soft construction and a spandex gusset reduce chafing and make longer wear comfortable during active use.
• Side Zip Pocket: A zip pocket on the side offers secure storage for small items when off the board or walking the beach.
• Velcro Fly and Drawstring: Combined closure keeps the waist secure during vigorous movement and provides simple size adjustment.

Who It's For

The O'NEILL 21 in boardshorts are aimed at men who need a functional swim short for surfing, paddleboarding, or active beach days and who prefer a below-the-knee fit. They suit buyers who value stretchy, quick-drying fabric and appreciate added features like a zip pocket and reinforced fly for secure wear.

Those who want a very short trunk, boardshorts with heavy insulation, or a tailored formal beach look should look elsewhere. Also, shoppers who require very precise sizing should check fit notes carefully, as customer feedback reports mixed sizing where some find them true-to-size and others find them slightly large.
