O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Stretch Fit 289

Our review of the O'NEILL Men's 21 in Solid Boardshorts finds them best suited for men who want a durable, comfortable swim short that dries fast and moves with activity. These boardshorts earn their place in a rotation because of the combination of Hyperfreak stretch for unrestricted movement and Hyperdry quick-dry technology that reduces soggy discomfort after the water. The 21 in outseam sits below the knee for coverage without feeling long, and practical touches like a side zip pocket and a velcro patch pocket keep essentials secure.

Key Features

• 21 in outseam: Provides below-the-knee coverage that most men find comfortable for surfing, swimming, and casual beachwear.
• Hyperfreak stretch fabric: Moves in all directions with the wearer so paddling, diving, and walking feel unrestrictive.
• Hyperdry DWR treatment: The quick dry finish shortens dry time after exiting the water and reduces that heavy wet feeling.
• Anti-rash Hyperthread: Internal stitching and fabric choice minimize chafing during extended activity.
• Secure storage: A side zip pocket plus a velcro patch pocket on the right leg keep small items safe when active.
• Traditional closure: Velcro fly with a spandex gusset and drawstring gives a reliable fit while in and out of the water.

Who It's For

These boardshorts are aimed at men who need multifunctional swimwear for surf sessions, pool days, and travel. The quick-dry fabric and stretch make them a good pick for anyone who transitions between water and land during a day and wants minimal drying time.

They are less appropriate for those seeking very short or fashion-forward streetwear trunks, or for swimmers who prefer compression swimwear for lap training. Also, men who want a baggier, longer leg might prefer a different cut.

Pros & Cons

Pros

• Comfortable, stretchy material that moves with activity and reduces restriction.
• Fast-drying Hyperdry treatment that cuts down on dampness after use.

Cons

• Sizing can be mixed; some customers report they run a bit big while others find them true to size, so trying your usual size is advised.
• The 21 in outseam may be too long for men who prefer short swim trunks that sit above the knee.
