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

Our review of the O'NEILL Men's 21 in Solid Boardshorts finds them best for active beachgoers and casual swimmers who want reliable fit and fast drying performance. The single biggest reason to buy is the combination of Hyperfreak stretch and Hyperdry quick-dry technology, which lets the shorts move with you and shed water quickly after surf or a pool session. Fit runs slightly variable for some buyers, but the below-the-knee 21 in outseam gives a modern length that most buyers praised for comfort and coverage.

Key Features

• 21 in outseam: Provides a below-the-knee fit that works well for surfing, swimming, and casual wear without riding up.
• Hyperfreak stretch fabric: Stretch construction moves with the body in all directions for unrestricted activity and better mobility.
• Hyperdry technology: DWR quick-dry treatment reduces time spent wet, making these practical for back-to-back water activities.
• Anti-rash Hyperthread: Thread and construction aimed at minimizing chafing during long sessions in the water or on a board.
• Side zip pocket: A secure zip pocket on the leg keeps small items like keys or cards protected while active.
• Velcro fly and drawstring: A reinforced fly with spandex gusset and drawstring closure balances secure fit with comfort during movement.

Who It's For

These boardshorts suit men who spend time surfing, paddleboarding, or using the beach and pool frequently and need a pair that dries quickly and stretches with movement. The 21 in outseam and modern stripe styling make them a good choice for those who prefer a knee-coverage length with a clean look.

Shoppers who need precise sizing for tailored looks or those who want shorter trunks under the knee might look elsewhere; customer feedback shows sizing can be mixed with some finding them slightly large, so try your usual size or consult the size guide when possible.
