O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Stretch Comfort 65

Our review of the O'NEILL Men's 21 in Solid Boardshorts finds them best for men who want reliable swim trunks that balance comfort, coverage and quick drying for beach and active water use. These boardshorts stand out because of the combination of Hyperfreak stretch that moves with you and Hyperdry quick dry technology, so they feel comfortable on and off the water. The 21 in outseam gives a below-the-knee fit that many customers praised for length and style, while the Velcro pocket and drawstring keep essentials secure.

Key Features

• 21 in outseam: Provides a below-the-knee fit that many reviewers found to be a balanced length for both swimming and casual wear.
• Hyperfreak stretch: Fabric stretches in all directions so the shorts move naturally during surfing, swimming or beach games.
• Hyperdry quick dry: DWR treatment and Hyperdry technology reduce wet time so the shorts dry faster after a swim.
• Anti-rash Hyperthread: Construction and fabric choices reduce chafing and increase comfort during extended activity.
• Secure storage: Velcro patch pocket at the right leg and a side zip pocket give room for small items while keeping them secure.
• Practical closure: Velcro fly with spandex gusset and drawstring ensures a snug adjustable fit for active use.

Who It's For

These boardshorts are ideal for men who want an active swim short with modern stretch and quick dry performance. They work well for surfers, pool swimmers, or anyone who transitions from water to shore and prefers a slightly longer, below-the-knee cut.

Men seeking a lined swim brief or those who prefer a much shorter inseam should look elsewhere, since these are unlined and designed as traditional boardshorts with a 21 in outseam and no internal mesh lining.
