O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Stretch Fit 88

In this review of the O'NEILL Men's 21 in Solid Boardshorts the bottom line is clear: these are best for men who want a comfortable, quick-drying boardshort that sits just below the knee and moves with them. The review focuses on fit, fabric performance and real-world comfort during beach days, surf sessions, or poolside hangouts. The combination of Hyperfreak stretch and Hyperdry technology is the single biggest reason to consider these shorts, delivering mobility and rapid dry time in a durable polyester build.

Key Features

• 21 in outseam: Provides a below-the-knee fit that many customers described as coming just above the knee for a modern, versatile length.
• Hyperfreak stretch: The fabric stretches in all directions so the shorts move with you during paddling, running or bending without feeling restrictive.
• Hyperdry quick-dry: DWR treatment and Hyperdry technology reduce soak time so the shorts dry rapidly after exiting the water.
• Anti-rash Hyperthread: Smooth construction and a spandex fly gusset help prevent chafing during extended activity.
• Practical storage: A side zip pocket and a velcro patch pocket on the right leg give secure options for small items while active.
• Secure fit: Velcro fly, spandex fly gusset and drawstring closure provide a reliable waist adjustment for varied use.

Who It's For

These boardshorts are ideal for men who prioritize mobility and quick drying in a swim trunk: surfers, paddleboarders and active beachgoers will appreciate the Hyperfreak stretch and Hyperdry treatment. The below-the-knee 21 in outseam offers modern styling and additional coverage for those who prefer longer shorts.

Shoppers who want a technical trunk with pockets and anti-rash details will find these well suited to regular water activity. Those who prefer very short swim trunks or require a tailored dressier short should look elsewhere, since this design emphasizes function and a casual, athletic fit.
