O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Stretch Fit 288

In this review of the O'NEILL Men's 21 in Solid Boardshorts the bottom line is simple: these are well-made swim trunks for men who want comfortable movement and fast drying after the water. Built with Hyperfreak Stretch and Hyperdry technology, the shorts emphasize mobility and quick moisture release, making them a reliable choice for surfers, swimmers, or anyone active on warm days. The 21 in outseam gives a below-the-knee length that most reviewers found comfortable and true to the intended style, while details like a side zip pocket add practical value.

Key Features

• 21 in outseam: a below-the-knee length that provides modest coverage and a classic boardshort silhouette while still allowing freedom to move.
• Hyperfreak Stretch fabric: four-way stretch material that moves with the body for surfing, beach sports, or casual wear without restricting motion.
• Hyperdry quick-dry: a DWR treatment and fabric tech that sheds water rapidly so the shorts dry faster between sessions.
• Anti-rash Hyperthread: construction designed to reduce chafing and make the shorts comfortable during extended wear in and out of the water.
• Velcro fly and drawstring: secure closure with a spandex fly gusset for added comfort and fit adjustment when active.
• Side zip pocket: a zippered pocket on the right leg for safe short-term storage of keys or small items.

Who It's For

The O'NEILL 21 in boardshorts are best for men who do water sports or active beach days and want a below-knee fit with stretch and fast drying performance. The fabric and finish suit surfers, paddleboarders, swimmers, and anyone who prefers no-mesh or minimal lining in their swimwear.

Those who want a very short cut, a built-in mesh liner, or a dramatically slim fashion silhouette should look elsewhere; these are tailored for functional water performance and modest coverage rather than brief-style swim trunks.

Pros & Cons

Pros

• Comfortable four-way stretch that accommodates dynamic movement in the water.
• Fast-drying Hyperdry treatment cuts down on wet time after swimming or surf sessions.
• Well-made details like the spandex fly gusset and secure side zip pocket add usability and comfort.
• Classic 21 in length and durable polyester construction hold up for casual and active use.

Cons

• Sizing feedback is mixed; some buyers find them true to size while others report they run a bit large, so sizing carefully matters.
• No mesh lining may be a drawback for those who prefer that feel or extra support in swim trunks.
