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

In this review of the O'NEILL Men's 21 in Solid Boardshorts the bottom line is simple: these are a comfortable, reliable pair of swim trunks for men who want a classic look and functional performance at the beach or pool. The single biggest reason to buy is the quick dry DWR treatment combined with a soft, light ultrasuede-like fabric that moves with you; the reviewer found them comfortable for active days in and out of the water while still looking neat enough for casual wear.

Key Features

• Ultrasuede fabric: soft and light construction lets you move easily during surf sessions or beach games without feeling weighed down.
• Quick dry DWR treatment: accelerates dry time after swimming so the shorts feel less soggy and more comfortable off the water.
• 21 in outseam: a length that sits just above the knee for a classic boardshort silhouette and balanced coverage.
• Velcro fly and drawstring: secure closure with a spandex fly gusset and drawstring that keeps the fit stable during activity.
• Patch pocket: Velcro patch pocket on the right leg provides useful storage for small items when on land.
• Allover stripe design: a versatile solid/stripe appearance that pairs well with tees or rash guards for a clean, casual look.

Who It's For

These boardshorts are best suited to men who want a traditional boardshort fit with modern quick-dry performance. They work well for surfers, poolside lounging, or anyone who prefers a durable polyester short that dries fast and keeps a neat profile thanks to the 21 in outseam.

Those who need a lined swim brief, a very tight athletic fit, or compression style swimwear should look elsewhere; also buyers who prefer a shorter cut may find the length too long. Sizing has mixed feedback among customers, so consider trying your normal waist size first and consult the brand size chart if between sizes.
