O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Stretch Comfort 319

Our review of the O'NEILL Men's 21 in Solid Boardshorts finds them best suited for men who want a below-the-knee swim short that dries fast and moves with the body. The single biggest reason to buy is the Hyperfreak stretch fabric paired with Hyperdry technology, which offers reliable mobility plus rapid dry time for beach days, surf sessions, or poolside lounging. The shorts feel durable and comfortable in active use, and the included right-leg zip pocket adds practical storage without bulk.

Key Features

• 21 in outseam: A below-the-knee length that provides coverage while keeping movement unrestricted for paddling or walking.
• Hyperfreak stretch: Four-way stretch fabric moves with you in all directions, reducing restriction when swimming or bending.
• Hyperdry quick-dry: Durable water repellent treatment and quick-dry construction cut drying time after getting out of the water.
• Anti-rash Hyperthread: Soft seam and fabric treatment minimize chafing so extended wear stays comfortable.
• Secure storage: Velcro patch pocket and side zip pocket give room for small essentials without weighing the shorts down.
• Comfort closure: Velcro fly with spandex fly gusset and drawstring ensures an adjustable, locked-in fit for active use.

Who It's For

These boardshorts are a strong pick for surfers, swimmers, and men who want quick-drying shorts for travel or beach trips. The stretch fabric and anti-rash treatment make them especially good for anyone doing active water sports who needs freedom of movement and comfort when wet.

Men who prefer very long or very short trunks, or who need built-in compression liners, may want to look elsewhere. Also, shoppers who are extremely particular about exact size should review the size notes, since some customers found sizing mixed compared with others who reported a true-to-size fit.
