Men's 21 in Solid Boardshorts for Men - Quick Dry Stretch

In this review the O'NEILL Men's 21 in Solid Boardshorts stand out as a dependable choice for swimmers and beachgoers who want a below-the-knee fit with performance fabrics. The bottom line: these boardshorts combine a comfortable hyperstretch construction with fast drying and anti-rash details, making them especially useful for active days in the water or casual wear by the shore. Our review finds them most appealing for men who prioritize mobility, quick dry time and a classic stripe look that holds up to regular use.

Key Features

• 21 in outseam: The below-the-knee length offers modest coverage while staying practical for surf and swim without restricting movement.
• Hyperfreak Stretch: The stretch fabric moves in all directions so paddling, walking and climbing feel less restrictive and more natural.
• Hyperdry technology: A quick dry DWR treatment reduces wet time after exiting the water so you dry faster between sessions.
• Anti-rash Hyperthread: Construction and fabric choices minimize chafing so the shorts stay comfortable during long activities.
• Functional storage: A side zip pocket and a Velcro patch pocket provide secure places for small items when off the water.
• Durable build: Polyester construction and reinforced fly with spandex gusset keep the shorts resilient through repeated wear.

Who It's For

The O'NEILL 21 in boardshorts are best for men who want a traditional boardshort length with modern fabric performance; surfers, swimmers and active vacationers will appreciate the stretch and quick dry features. The comfortable anti-rash construction and secure pockets make them a solid option for longer beach days and mixed activities.

Those who want a shorter trunk or a tailored swim brief should look elsewhere, and anyone seeking natural fiber swimwear or insulated cold-water suits will not find those options here. Shoppers who need precise sizing should note that feedback on size runs mixed, so consider trying your usual waist or checking the size guide.
