O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Stretch Fit 123

In this review of the O'NEILL Men's 21 in Solid Boardshorts the bottom line is simple: these are a reliable, comfortable pair of swim trunks for men who want a below-the-knee fit and fast drying performance. The shorts stand out for their quick dry Hyperdry finish and stretch fabric that moves with you, making them a good pick for active beach days, surfing, or poolside lounging. Overall they offer practical features without fuss: a secure velcro fly and drawstring, a zip pocket for small items, and a lightweight polyester construction that resists water retention.

Key Features

• 21 in outseam: Provides a below-the-knee fit that many customers find comfortable and modern for boardshorts.
• Hyperfreak stretch fabric: Allows the shorts to move in all directions so they stay comfortable during surf, swim, or beach games.
• Hyperdry technology: Quick dry DWR treatment reduces water retention and shortens dry time after exiting the water.
• Anti-rash Hyperthread: Construction and inner gusset reduce chafing so the shorts stay comfortable during long sessions.
• Secure storage: A side zip pocket plus a velcro patch pocket keep small items safe while active.
• Durable closures: Velcro fly with a spandex fly gusset and drawstring give a reliable fit in and out of the water.

Who It's For

The shorts are best for men who prefer a classic boardshort silhouette that finishes just below the knee and want fabrics designed to dry fast and move with them. They suit surfers, swimmers, and anyone who spends extended time on the beach and values comfort, stretch, and quick dry performance.

Those who want a shorter swim trunk or a lined brief-style suit should look elsewhere, as these are full-length boardshorts in 100% polyester with focus on mobility and water resistance rather than interior lining or compression fit.

Pros & Cons

Pros

• Comfortable below-the-knee length that many users say fits true and looks modern.

Cons
