O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Stretch Fit 58

Our review of the O'NEILL Men's 21 in Solid Boardshorts finds a dependable swim short for men who want a below-the-knee fit with functional features. These boardshorts stand out for their quick dry Hyperdry technology and stretchy Hyperfreak fabric that moves well during paddling, beach volleyball, or casual pool days. The construction balances comfort and utility with a velcro fly, drawstring waist and a secure side zip pocket for small items, making them a practical everyday swim trunk rather than a fashion statement.

Key Features

• 21 in Outseam: The below-the-knee length gives fuller coverage and a classic boardshort profile for active water use.
• Hyperfreak Stretch Fabric: Four-way stretch lets the shorts move with you during surf and shore activities without restricting motion.
• Hyperdry Quick Dry: Durable water repellent treatment and Hyperdry tech reduce soak time so the shorts dry faster after a swim.
• Anti-Rash Hyperthread: Flat seams and soft thread construction minimize chafing during long sessions in and out of the water.
• Secure Storage: A side zip pocket plus a velcro patch pocket provide room for small items while keeping them secure during activity.
• Practical Closure: Velcro fly with a spandex gusset and drawstring waist combine for a customizable, secure fit.

Who It's For

These boardshorts are best for men who want a functional swim trunk with a traditional boardshort length and fabric that supports active water sports. They appeal to surfers, paddle boarders, and swimmers who value quick drying and freedom of movement provided by stretch swim fabric.

Shoppers looking for a tailored or fashion-forward short, or those who prefer trunks that sit higher on the thigh, should look elsewhere. Also, if you need cargo-style storage or heavier fabric for rugged use, these lighter polyester boardshorts are not ideal.
