The Difference Between Board Shorts and Swim Trunks (and Which One You Should Wear)

When it’s time to shop for men's swimwear, two terms get thrown around interchangeably: swim trunks and board shorts. Is there really a difference? Does it matter?

Absolutely. Choosing the right one isn't just about style—it's about comfort, function, and getting the perfect pair for your beach day, vacation, or poolside afternoon. As experts in the art of island living, we're here to settle the debate for good. This is your guide to understanding the difference and finding your perfect fit.

What Are Swim Trunks? The All-Around Classic

Think of classic swim trunks as the original, versatile swimwear for men. They are the go-to choice for most beach and pool activities.

• Length: They typically have a shorter inseam, hitting anywhere from the upper thigh to just above the knee. This is the key feature of mens short swim shorts.

• Liner: They almost always feature a soft, breathable mesh liner inside. This provides support and prevents chafing during activities like swimming or walking.

• Waistband: They have a comfortable, elastic waistband, usually with a drawstring for an adjustable, secure fit.

• Best For: Lounging by the pool, casual swimming, beach games, and walking the boardwalk. Their versatility means you can easily throw on a t-shirt and head to a casual lunch.

What Are Board Shorts? The Performance Pick

Board shorts, as the name implies, were originally designed specifically for board sports like surfing, paddleboarding, and wakeboarding.

• Length: They are significantly longer, with an inseam that hits at or below the knee. This is to protect the surfer's legs from waxing and chafing on the board.

• Liner: True mens swim board shorts do not have a mesh liner. This is intentional, as a liner can become uncomfortable and restrictive during high-performance sports.

• Waistband: They feature a fixed, non-elastic waistband that closes with a lace-up tie and a velcro fly. This provides a super-secure fit that won't get pulled down by waves.

• Best For: Surfing, wakeboarding, and other serious water sports.

Swim Trunks vs. Board Shorts: The Key Differences

From Poolside to Patio: How to Style Your Swim Trunks

One of the greatest benefits of classic swim trunks is their versatility. They aren’t just for the water. With the right pairing, they can take you straight from the beach to the bar or cafe.

• The Look: Pair your Jams World swim trunks with a crisp, white linen shirt or a classic Jams World Rayon Shirt worn open. It’s a timeless, sophisticated look that’s perfect for a casual lunch.

• The Vibe: For an even more relaxed feel, simply throw on your favorite t-shirt. The shorter length of the swim trunks ensures the outfit looks intentional and stylish, not like you just rolled off the beach.

Your Questions, Answered (FAQ)

Q1. Can you wear underwear under swim trunks?
A. No, you shouldn't. The mesh liner is designed to be your support layer. Adding another layer can trap water, slow down drying, and lead to chafing and discomfort.

Q2. Are volley shorts the same as swim trunks?
A. They are very similar! "Volley shorts" is another term for shorter-length, liner-equipped shorts designed for activity (like beach volleyball) and swimming. They fall squarely in the swim trunk category.

Q3. How should swim trunks fit?
A. They should be snug at the waist without being tight, and the leg opening should be comfortable—not billowy, but not restrictive. The length is a matter of personal preference, but a mid-thigh cut is a timeless, flattering choice for most men.
