O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Comfort 179

In this review of the O'NEILL Men's 21 in Solid Boardshorts the bottom line is simple: these are a reliable, comfortable pair of swim trunks for men who want a below-the-knee fit and fast drying performance. Designed with Hyperfreak stretch for full range of motion and Hyperdry technology for rapid drying, the shorts feel light on water days and provide sensible storage with a side zip pocket. The review highlights fit, fabric behavior in and out of the water, and practical details like the velcro fly and drawstring that matter to regular swimmers and beachgoers.

Key Features

• 21 in outseam: delivers a below-the-knee fit that suits surfers and casual beachwear without riding up during activity.
• Hyperfreak stretch fabric: gives four-way mobility so the shorts move with you during swims, paddling, and beach sports.
• Hyperdry quick-dry treatment: speeds drying after exiting the water so you stay comfortable between sessions.
• Anti-rash Hyperthread: construction minimizes chafing so the shorts remain comfortable during long wear.
• Side zip pocket: provides secure storage for small items when on the go, backed by a velcro patch pocket on the leg.
• Velcro fly with gusset and drawstring: combines a secure closure and adjustable waist for a consistent fit.

Who It's For

These boardshorts are best for men who prefer a traditional, modest length and active use - surfers, swimmers, and anyone who wants a quick-drying trunk that supports movement. The stretch fabric and anti-rash threading make them a good pick for days spent in the ocean or playing beach sports.

Shoppers who want a lined swim brief or those who need a very tailored or short inseam should look elsewhere; these are true boardshorts with a 21 in outseam and no mesh lining noted by some customers. Also check sizing guidance closely, as customers report mixed feedback on whether they run slightly large.

Pros & Cons

Pros

• Comfortable stretch that supports active movement without restriction.
• Quick-dry Hyperdry treatment reduces sogginess after swimming.
• Sturdy construction and material quality that customers praise for durability.
• Secure storage with side zip pocket plus velcro leg pocket for convenience.

Cons

• Sizing receives mixed feedback, so buyers should check measurements before ordering.
• No mesh lining reported by some customers, which may be a drawback for those who prefer lined trunks.
