O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Stretch Comfort 85

In this review of the O'NEILL Men's 21 in Solid Boardshorts the bottom line is simple: these are durable, comfortable boardshorts designed for active beach days and casual wear. Built with Hyperfreak stretch and O'NEILL Hyperdry technology, the shorts move with you and dry quickly after swimming. The 21 in outseam falls just below the knee on most wearers and the combination of a spandex gusseted fly, drawstring waist and a secure zip patch pocket make these shorts a reliable choice for anyone who wants swimwear that performs without fuss.

Key Features

• 21 in outseam: the below-the-knee length gives good coverage for surfing, paddling or walking the boardwalk while still allowing free leg movement.
• Hyperfreak stretch: four-way stretch fabric moves with your body so the shorts do not restrict when you paddle, dive or bend.
• Hyperdry quick-dry: DWR treatment speeds water release and reduces time spent in damp swimwear after leaving the water.
• Anti-rash Hyperthread: seam and fabric choices reduce chafing and make long sessions more comfortable.
• Secure pockets: a right-leg Velcro patch pocket plus a side zip pocket provide safe storage for small items at the beach or pool.
• Gusseted fly: spandex fly gusset with Velcro and drawstring closure maintains fit and comfort during activity.

Who It's For

The O'NEILL 21 in boardshorts are best for men who spend time in and around the water and need a reliable, quick-drying short that still looks casual on land. Surfers, paddleboarders and swimmers will appreciate the stretch and anti-rash details, while anyone who prefers a below-the-knee length will like the 21 in outseam.

Those who want a tailored, short inseam or a trunk-style swim brief should look elsewhere, and buyers who need heavy insulation or multi-layer cold-water gear should choose a dedicated wetsuit. Sizing can vary for some customers, so if you are between sizes try both or consult the brand size guide before purchasing.

Pros & Cons

Cons
