O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Stretch 188

In this review of the O'NEILL Men's 21 in Solid Boardshorts the bottom line is simple: these are a practical, comfortable pair of boardshorts for men who want a reliable below-the-knee swim short with modern performance fabrics. The reviewer found the Hyperfreak stretch and Hyperdry quick-dry treatment make them especially useful for active days at the beach or pool, and the anti-rash Hyperthread construction keeps long sessions comfortable. Fit opinions vary slightly among buyers, but most praise the length, material quality, and overall comfort.

Key Features

• 21 in outseam: The below-the-knee length provides modest coverage and works well for swimming or casual beachwear without riding up.
• Hyperfreak stretch fabric: Four-way stretch moves with you for paddling, surfing, or general activity so motion feels unrestrictive.
• Hyperdry quick-dry treatment: Durable water repellent speeds drying time so shorts do not stay soaked between water sessions.
• Anti-rash Hyperthread: Smooth internal seams and fabric choices reduce chafing for longer comfort during active use.
• Side zip pocket: A secure zip pocket at the side lets you carry small items like a key or card without them falling out.
• Velcro fly and drawstring: The combination of velcro fly, spandex gusset and drawstring closure keeps the waist secure and adjustable for different body shapes.

Who It's For

These boardshorts suit men who want a versatile swim short for active water sports or everyday beach use. The stretch fabric and quick-dry finish are particularly helpful for surfers, paddleboarders, or anyone who moves a lot in the water and needs quick turnover between sessions.

They may be less appealing to buyers who prefer a loose fit with heavy mesh lining or those looking for a much shorter swim brief; customers note there is no mesh lining and sizing runs a bit mixed, so those between sizes should consider trying them on or sizing according to personal preference.

Pros & Cons

Pros

• Comfortable four-way stretch fabric that moves with the body during activity.
• Quick-dry Hyperdry treatment reduces wet time after exiting the water.
• Secure storage with a velcro patch pocket and a side zip pocket for essentials.
• Anti-rash Hyperthread construction improves comfort during extended wear.

Cons

• Sizing feedback is mixed; some customers find them true to size while others say they run a bit large.
• No internal mesh lining, which some swimmers prefer for support and ventilation.
