O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Stretch 187

Our review finds the O'NEILL Men's 21 in Solid Boardshorts best for men who want a durable, comfortable swimsuit that performs on and off the water. In this review the standout is the combination of Hyperfreak Stretch fabric and O'NEILL Hyperdry treatment, which together deliver unrestricted movement and rapid drying after a swim. The shorts sit just below the knee for modest coverage, include a secure side zip pocket for small essentials, and use anti-rash Hyperthread technology to reduce chafing during extended wear.

Key Features

• 21 in outseam: a below-the-knee fit that offers coverage without restricting movement for paddling or beach activities.
• Hyperfreak Stretch: four-way stretch fabric that moves with the body, making these shorts comfortable for surfing, swimming, and casual wear.
• Hyperdry quick dry: DWR treatment and Hyperdry technology speed up drying time so the shorts are ready to wear soon after leaving the water.
• Anti-rash Hyperthread: construction reduces friction and irritation during extended water sports or long days in the sun.
• Secure storage: a side zip pocket and a Velcro patch pocket provide places to keep keys or small items while active.
• Functional closure: velcro fly with spandex gusset and drawstring closure ensures a snug, adjustable fit.

Who It's For

The O'NEILL 21 in boardshorts are aimed at men who need a reliable all-purpose swim short for surfing, beach days, and poolside use. They suit active users who prefer a slightly longer outseam and value stretch fabric that follows dynamic movement.

Those who want a lined swim brief or who require very fitted trunks may want to look elsewhere, since these are designed as classic boardshorts with a focus on quick dry fabric and comfort rather than a mesh lining or very short inseam.
