Mossimo Board Shorts — Quick-Dry Swim Shorts
We designed our board shorts for guys who want performance swim gear without sacrificing style. These quick-dry shorts feature a secure velcro fly, mesh drainage vents, and deep side pockets with drain grommets. The four-way stretch fabric moves with you during paddling, diving, and beach volleyball.
Our board shorts use a lightweight polyester weave engineered to shed water fast. The fabric's hydrophobic finish prevents waterlogging, so you're not weighed down climbing back on a surfboard or running across hot sand. We added 8% spandex throughout for flexibility during high kicks and deep squats.
Sizing & fit guide
We cut our board shorts with a relaxed fit through the hips and thighs. The elastic waistband stretches two inches beyond your natural waist measurement, and the drawcord lets you cinch it snug when diving or body surfing.
Size Chart
Small fits waist 28-30 inches, Medium 32-34, Large 36-38, XL 40-42, XXL 44-46. If you’re between sizes, we recommend ordering up for the roomiest fit or staying at your usual size for a closer cut. The inseam stays at 9 inches across all sizes.
Pockets & secure storage
We built two deep side pockets that hold a phone, keys, or wallet without bulging. Each pocket measures 7 inches deep with reinforced stitching at stress points. The velcro fly stays closed through waves and waterslides, backed by a single snap button for redundancy.
A small zippered back pocket sits flat against your body and fits a car key or folded cash. We lined it with water-resistant fabric to keep contents dry during brief submersion. For guys who need more storage options, our cargo short collection includes multiple utility pockets with secure flap closures.

Buyer questions about Mossimo board shorts
No, our board shorts are designed without a mesh liner for maximum comfort and faster drying. The smooth interior fabric reduces chafing during extended wear. Many surfers and swimmers prefer this liner-free design because it allows you to wear your own compression shorts or swim briefs underneath if desired.
Our quick-dry fabric typically dries in 40 to 60 minutes of active wear after leaving the water. Hang drying speeds this up to about 30 minutes in warm, breezy conditions. The mesh drainage vents and hydrophobic finish work together to shed water faster than standard swim trunks.
Yes, these board shorts work well for casual everyday wear beyond swimming. The clean design and solid colors pair with t-shirts and tank tops for a relaxed summer look. The quick-dry fabric also handles sweat well during hot weather walks or outdoor activities.
Board shorts typically have a longer inseam, no mesh liner, and more secure closures like velcro flies and drawcords. Swim trunks usually feature a shorter cut, elastic-only waistbands, and built-in mesh briefs. Board shorts are designed for active water sports like surfing, while swim trunks work best for casual pool swimming and lounging.
The side pockets are water-resistant but not fully waterproof — they drain quickly through bottom grommets to prevent waterlogging. The small back zippered pocket has water-resistant lining that keeps contents dry during brief submersion, but we don’t recommend submerging electronics for extended periods. For full waterproof storage, consider a separate dry bag.
Our board shorts run true to standard men’s sizing. The elastic waistband provides two inches of stretch beyond the stated waist measurement, and the adjustable drawcord ensures a custom fit. If you prefer a looser fit or are between sizes, we recommend ordering one size up.
Always close the velcro fly completely before washing to prevent it from catching on other garments. Washing board shorts inside out provides extra protection. If velcro does snag fabric, gently pull it free rather than yanking, which can damage both the velcro and the caught material.
