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

Our review of the O'NEILL Men's 21 in Solid Boardshorts finds them best for men who want a comfortable, versatile swim trunk that performs in and out of the water. These boardshorts stand out for their combination of quick dry Hyperdry technology and a four-way Hyperfreak stretch that lets the fabric move with active use. The 21 in outseam lands just above the knee on most wearers and the built-in Velcro fly with spandex gusset and drawstring keeps the fit secure during swims or beach activities, making these a practical pick for everyday swim and surf use.

Key Features

• Hyperfreak Stretch: Four-way stretch fabric allows natural movement for swimming, surfing, or casual wear without restriction.
• Hyperdry Quick Dry: DWR treatment speeds drying time so the shorts dry fast after a swim or surf session.
• Anti-Rash Hyperthread: Soft construction and thoughtful stitching reduce chafing and make them comfortable for extended wear.
• Secure Storage: A side Velcro zip pocket on the right leg provides safe space for small items while active.
• Adjustable Fit: Velcro fly, spandex gusset and drawstring closure combine for a confident, customizable fit.
• Classic Styling: Allover Santa Cruz stripe print with a brand patch at the left leg gives a timeless beach look.

Who It's For

The O'NEILL 21 in boardshorts are ideal for men who want a durable swim short that doubles as casual beachwear or active surfwear; the stretch fabric and compact 21 in outseam make them particularly suited to surfers, swimmers, and anyone who prefers shorts that sit just above the knee. The quick dry finish benefits travelers and day swimmers who move between water and land frequently.

Men who prefer ultra-long boardshorts or minimalistic trunks may want to look elsewhere, and those who need a compression liner or performance-specific pockets for heavy electronics should consider more specialized swimwear. Sizing can be mixed for some shoppers, so check waist measurements if you prefer a very tight or very loose fit.
