O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Stretch Comfort 169

In this review the O'NEILL Men's 21 in Solid Boardshorts are examined as a reliable swim and activity short for men who want coverage just below the knee and fabric that moves with them. The single biggest reason to buy is the combination of Hyperfreak stretch and Hyperdry quick-dry treatment, which together make these trunks comfortable for water, beach, and active days when rapid drying and freedom of movement matter most.

Key Features

• 21 in outseam: Provides a below-the-knee fit that suits riders, surfers, and men who prefer longer boardshorts without restricting leg movement.
• Hyperfreak stretch fabric: Four-way stretch construction lets the shorts move with the body for swimming, paddling, or bending without pulling.
• Hyperdry quick-dry treatment: Durable water repellent finish speeds evaporation so the shorts dry faster after leaving the water.
• Anti-rash Hyperthread: Smooth construction and fabric choices reduce chafe and make the shorts comfortable during extended activity.
• Velcro side pocket: A right-leg zip patch pocket gives secure storage for small items while on the go.
• Secure fly and drawstring: Velcro fly with a spandex gusset and drawstring closure keep the waist secure during active use.

Who It's For

The O'NEILL 21 in boardshorts are best for men who spend time surfing, swimming, or doing beach activities and want a longer boardshort with modern stretch and quick-dry performance. They work well for those who prefer a clean stripe design and need a secure pocket for small essentials.

Men who want a lined swim brief or who need a very tapered, fashion-forward short may want to look elsewhere, as these are designed as functional boardshorts with a practical fit and no mesh lining noted by one customer.

Pros & Cons

Pros

• Durable construction and solid material quality deliver a dependable feel and finish.

Cons

• Sizing is mixed in customer reports, with some finding them true to size and others saying they run a bit large.

Our Verdict

The O'NEILL 21 in Solid Boardshorts are a solid choice for active beachgoers who need stretch, quick-drying performance, and a longer cut that stays comfortable during movement. Given the fabric technologies and practical details, they offer good value for men seeking functional boardshorts rather than fashion-focused swimwear.

Frequently Asked Questions

Do these boardshorts dry quickly?
Yes; the Hyperdry DWR treatment is designed to accelerate drying compared with standard polyester shorts.

Are these lined?
Customers note there is no mesh lining, so they are structured as unlined boardshorts with a spandex gusset in the fly for comfort.

How do they fit?
Fit is generally true to size for many, offering a relaxed below-the-knee cut, but some buyers report they run slightly large so checking waist sizing is advised.
