O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Comfort 172

In this review of the O'NEILL Men's 21 in Solid Boardshorts the bottom line is simple: these are a practical, comfortable swim short for guys who want reliable fit and fast drying without fuss. The reviewer found the 21 in outseam hits below the knee for a classic boardshort silhouette, and the combination of Hyperfreak stretch and Hyperdry technology makes them move and dry quickly after water time. They are best for beach days, active water sports, or casual poolside wear where quick drying and comfort matter most.

Key Features

• 21 in Outseam: Provides a below-the-knee fit that works well for surf, paddleboarding, and casual wear while maintaining coverage.
• Hyperfreak Stretch: The fabric moves with the body in multiple directions so the shorts feel less restrictive during active use.
• Hyperdry Technology: Quick-dry treatment reduces water retention so trunks dry faster between sessions and are more comfortable out of the water.
• Anti-Rash Hyperthread: Internal construction minimizes chafing so long days on the beach or board are more comfortable.
• Side Zip Pocket: Provides secure, water-resistant storage for small items like keys or a card when you are active.
• Velcro Fly and Drawstring: Dual closure keeps the fit adjustable and secure during movement.

Who It's For

These boardshorts suit men who want a traditional boardshort length with modern performance fabric; they are ideal for surfers, swimmers, and anyone who spends long days at the beach and needs shorts that dry quickly and resist chafing. The secure zip pocket and durable polyester construction also make them a practical choice for travel or active vacations.

Men who prefer very stretchy, compression-style swimwear or those seeking a minimal shorter cut should look elsewhere, since these are designed as a below-the-knee boardshort with a classic fit rather than a brief or short athletic trunk.

Pros & Cons

Pros

• Comfortable, true-to-size fit that sits below the knee for good coverage and a classic look.
• Fabric dries quickly due to the Hyperdry DWR treatment, reducing soggy comfort after swimming.
• Functional details like the side zip pocket and drawstring keep valuables secure and the fit adjustable.
• Anti-rash construction makes long wear on a board or in the sand more comfortable.

Cons

• Stretch performance is mixed in customer reports, so the level of give may vary by size and batch.
• Some buyers note the logo and branding feel large for those who prefer minimal branding.
