O'NEILL Men's 21 in Solid Boardshorts - Quick Dry Stretch Fit 145

Our review of the O'NEILL Men's 21 in Solid Boardshorts finds them best suited for swimmers and beachgoers who want a below-the-knee fit with functional performance features. The single biggest reason to buy is the combination of the Hyperfreak stretch fabric and Hyperdry treatment, which deliver a flexible, quick-drying short that moves with you whether surfing, paddling, or walking the boardwalk. Fit is generally true to size but opinions vary, so read the fit notes before finalizing a size.

Key Features

• 21 in outseam: Provides a classic below-the-knee length that many users find comfortable for both water and casual wear.
• Hyperfreak stretch: Fabric stretches in all directions so the shorts move with you during active water sports without binding.
• Hyperdry quick dry: DWR treatment speeds up drying time so the shorts shed water and feel lighter after swims.
• Anti-rash Hyperthread: Construction reduces chafing and makes the shorts comfortable for extended wear in and out of the water.
• Side zip pocket: A secure zip pocket stores small items when you need to leave your board or towel unattended.
• Velcro fly and drawstring: Combined closure keeps the waist adjustable and secure during active use.

Who It's For

These boardshorts are ideal for men who want a versatile swim short that works for surfing, casual beach days, and travel. The stretch fabric and quick-dry finish suit people who move a lot or transition between water and land activities.

They are less ideal for buyers who prefer built-in mesh liners or a very tailored, fashion-forward short; customers seeking a tighter, above-the-knee cut should look elsewhere. Also note that sizing feedback is mixed, so those between sizes may want to try both to find the best fit.

Pros & Cons

Pros

• Comfortable stretch fabric that allows full range of motion for active use.
• Quick-dry Hyperdry treatment reduces post-swim dampness and weight.
• Secure side zip pocket and practical Velcro pocket provide useful storage options.
• Durable build and color options that customers praise for material quality and look.

Cons

• Sizing reports are mixed; some customers find them true to size while others report a roomier fit.
• There is no mesh liner for those who prefer that style of support and ventilation.

Our Verdict

These boardshorts are a strong choice for active beach users who need mobility and fast drying without sacrificing coverage; the stretch fabric and Hyperdry finish offer good value for surfers and swimmers.
