Men's 21in Solid Boardshorts - Water Resistant Quick Dry Swim Trunks

In this review of the O'NEILL Men's 21 in Solid Boardshorts the bottom line is simple: these are reliable surf-ready trunks for men who want a comfortable, quick-drying short with a classic look. The strongest reason to buy is the combination of lightweight ultrasuede-style polyester and a DWR quick dry finish that makes them feel soft on the skin while shedding water fast after a session. The 21 in out seam lands just above the knee for a traditional boardshort silhouette that works both in and out of the water.

Key Features

• Ultrasuede fabric: Soft, light polyester construction lets you move freely and feels comfortable against the skin during long days in the surf.
• Quick dry DWR treatment: Durable water repellency reduces dry time so the shorts stop feeling heavy once you leave the water.
• Secure closure: Velcro fly with a spandex gusset and drawstring provides a snug, adjustable fit that stays put during active use.
• Practical pocket: Velcro patch pocket at the right leg keeps small items secure and accessible while you are on the beach.
• Classic fit and length: 21 in out seam gives a versatile length that sits just above the knee for balanced coverage and mobility.

Who It's For

These boardshorts are aimed at men who surf, swim, or spend heavy time around water and want a dependable pair of shorts that dry quickly and feel soft. The classic solid design and conservative 21 in length make them a good choice for casual beach days, poolside wear, or travel where a versatile short is useful.

Those who prefer built-in mesh liners, ultra-compressed performance fabrics, or a very tight athletic cut may want to look elsewhere; these are made from 100% polyester with no mesh lining and lean toward a traditional boardshort fit rather than a compression swim brief.
