O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Stretch Comfort 290

Our review of the O'NEILL Men's 21 in Solid Boardshorts finds them best for men who want a below-the-knee swim short that balances movement and quick drying for active days at the beach or pool. The single biggest reason to buy is the combination of Hyperfreak Stretch mobility with Hyperdry quick-dry treatment, which means these shorts move with you during paddle sessions or beach volleyball and then dry rapidly when you get out of the water.

Key Features

• 21 in outseam: The below-the-knee fit offers modest coverage and a contemporary look without restricting leg movement.
• Hyperfreak Stretch fabric: Four-way stretch construction lets the shorts flex with dynamic activities like surfing or running on sand.
• Hyperdry technology: Durable water repellent treatment and quick-dry polyester reduce clamminess after leaving the water.
• Anti-rash Hyperthread: Smooth stitching and fabric choices minimize chafing during extended wear or repeated surf sessions.
• Side zip pocket: A zippered pocket on the side secures small items when you are on the move.
• Velcro fly and drawstring: Secure closure with a spandex gusset provides a comfortable fit and easy adjustment.

Who It's For

These boardshorts suit men who want a practical swim short that performs for active water sports and casual beachwear; the stretch fabric and quick dry finish are useful for surfers, paddle boarders, and anyone who changes between water and land activities. The 21 in outseam is aimed at people who prefer a below-the-knee length rather than short trunks.

Shoppers who prefer a lined brief or want a very slim, fashion-forward short may want to look elsewhere because these are unlined and built for comfort and movement rather than a tailored fashion fit. If you need a very fitted rise for formal swim competitions, a performance brief would be a better choice.

Pros & Cons

• Comfortable stretch fabric that allows full range of motion for active use.

Cons

• Sizing opinions are mixed among customers, so some buyers may need to size up or try on to find the ideal fit.
