O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Stretch Fit 76

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 balances movement and quick drying for active beach days. The biggest reason to buy is the combination of Hyperfreak stretch and Hyperdry treatment, which together deliver comfortable, unrestricted movement and rapid dry time after water activities. The review highlights practical details like a side zip pocket and a Velcro patch pocket, and notes the fit trends customers report so you can pick the right size.

Key Features

• 21 in outseam: The below-the-knee length provides modest coverage while keeping legs free for paddling, swimming, and casual wear.
• Hyperfreak stretch: Multi-directional stretch fabric moves with you during surfing or beach sports so the shorts never feel restrictive.
• Hyperdry quick dry: Durable water repellent treatment reduces water retention so the boardshorts dry rapidly between sessions.
• Anti-rash Hyperthread: Smooth construction and fabric help minimize chafing for longer comfort on wet skin or after extended activity.
• Secure storage: A side zip pocket plus a Velcro patch pocket at the right leg keep small items safe and accessible while active.
• Practical closure: Velcro fly with a spandex gusset and drawstring closure offers a reliable fit and a bit of stretch at the waist.

Who It's For

These boardshorts are ideal for men who spend time in the water or on the beach and want a pair that dries fast and allows full range of motion, such as surfers, paddleboarders, and swimmers who prefer a traditional boardshort silhouette. The 21 in outseam sits just below the knee for those who like modest coverage without sacrificing mobility.

Those who prefer lined trunks or a very slim styling may want to look elsewhere, since customers note there is no mesh lining and the fit runs slightly varied for some. If you need a brief-style swimwear or performance shorts with an internal liner, consider other styles designed specifically for that use.

Pros & Cons

Pros

• Comfortable stretch fabric that moves in all directions for active use.
• Fast drying Hyperdry treatment reduces clamminess after exiting the water.
• Good storage with both a zip pocket and a Velcro patch pocket for essentials.
• Solid build and color options that customers praise for material quality and look.

Cons

• Sizing is mixed in reviews, with some customers finding them slightly large; try your normal size but check measurements.
• No internal mesh lining, which may be a drawback for buyers who prefer that feature for support.
