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

Our review of the O'NEILL Men's 21 in Solid Boardshorts finds them best suited to men who want a reliable, comfortable pair of swim trunks that dry fast after a dip. The biggest reason to buy is the combination of a Hyperdry DWR finish and lightweight ultrasuede construction that makes these shorts dry quickly and feel soft against the skin, so they work equally well for a day at the beach or laps at the lake.

Key Features

• Classic fit: The 21 in outseam and traditional cut provide a versatile silhouette that sits comfortably at the waist and offers full coverage without feeling baggy.
• Hyperdry DWR finish: Durable water repellent treatment speeds evaporation and reduces cling so shorts dry faster after swimming or surf sessions.
• Ultrasuede fabric: Soft, light polyester material moves easily with you for improved comfort during long days in and out of the water.
• Secure closures: Velcro fly with a spandex gusset and drawstring ensures a locked-in fit while you paddle or swim.
• Functional storage: Velcro patch pocket at the right leg keeps small items secure and accessible when ashore.
• Durability: Constructed from 100% polyester for long-term wear across multiple seasons of use.

Who It's For

These boardshorts are ideal for men who want a dependable pair of swim trunks for mixed water activities like surfing, paddleboarding, or casual beach days. The quick-dry DWR treatment and lightweight ultrasuede make them particularly useful for travelers or anyone who moves between water and land frequently.

Men who need highly technical stretch fabrics for competitive swimming or those who prefer very short or compression-style swimwear should look elsewhere, as these are designed for classic boardshort comfort and general functionality rather than race-level performance.

Pros & Cons

Pros

• Quick-dry Hyperdry DWR finish reduces dry time after swimming.

• True-to-size fit and a 21 in outseam that works well for most casual uses.
