O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Stretch Comfort 110

In this review of the O'NEILL Men's 21 in Solid Boardshorts the bottom line is clear: these are a solid choice for men who want durable, comfortable swim trunks with a below-the-knee fit and reliable quick-dry performance. The reviewer found the combination of Hyperfreak Stretch and Hyperdry treatment makes them move with you and dry fast after a surf or pool session, while the anti-rash Hyperthread keeps skin comfortable during long wear. They are best for active beach days where stretch, fit, and practical pockets matter most.

Key Features

• 21 in outseam: Provides a below-the-knee fit that covers more of the thigh for modesty and surf-appropriate coverage.
• Hyperfreak Stretch fabric: Delivers multi-directional stretch so the shorts move with you during paddling, diving, or casual activity.
• Hyperdry quick-dry treatment: DWR finish reduces water retention so the shorts shed moisture and dry rapidly after exiting the water.
• Anti-Rash Hyperthread: Smooth construction and thread technology help prevent chafing during extended use in and out of the water.
• Side zip pocket: Adds secure storage for small essentials so you can keep keys or a card safe while active.
• Velcro fly with drawstring: Ensures a secure fit with the added comfort of a spandex gusset at the fly for flexibility.

Who It's For

These boardshorts are best for men who spend time surfing, swimming, or engaging in beach sports and want a functional, stretchable short that sits below the knee. The fabric and construction suit those who prioritize quick drying, freedom of movement, and straightforward styling.

Men looking for lined swim trunks or a very tailored short might look elsewhere, since customers note there is no mesh lining and sizing can run slightly large for some. If a closer, shorter fit is preferred, consider a shorter inseam style.

Pros & Cons

Pros

• Comfortable multi-directional stretch makes active movement effortless and natural.
• Quick-dry Hyperdry finish reduces soggy feeling after water use.

Cons

• Sizing is mixed among buyers; some report they run a bit large so trying your normal size or sizing down may be needed.
• No mesh lining, which some swimmers expect for venting and support.
