Are board shorts suitable for swimming?

Board shorts are popular beachwear because of their casual style and comfortable fit. But are board shorts suitable for swimming?

Yes, board shorts¹ are suitable for recreational swimming and water activities, but they’re not ideal for competitive swimming because they create drag and lack support.

They’re great for surfing, beach sports, and lounging by the pool. Let’s explore when board shorts are the right choice and their pros and cons for swimming.

What are board shorts, and how are they different from swim trunks?

Board shorts are knee-length, loose-fitting shorts originally designed for surfers. They are made from quick-drying, lightweight materials like polyester or nylon.

Unlike swim trunks², board shorts don’t have built-in liners, offering a relaxed, casual fit. Swim trunks are shorter and usually have a mesh lining for support.

The design and fabric of board shorts provide comfort and mobility, making them popular for beach activities beyond swimming.

Key Differences Between Board Shorts and Swim Trunks

Feature	Board Shorts	Swim Trunks
Length	Knee-length or longer	Mid-thigh to above the knee
Fit	Loose and relaxed	More fitted with an elastic waistband
Lining	No built-in liner	Usually has a mesh lining for support
Purpose	Surfing, beach sports, casual wear	Swimming, water sports, casual wear
Style	Surf-inspired, sporty	More versatile in style and patterns

Board shorts are designed for active movements like surfing, which require a flexible fit. Swim trunks, on the other hand, provide more support and are better suited for general swimming.

Are board shorts comfortable for swimming?

Yes, board shorts are comfortable for recreational swimming because they’re lightweight and offer a relaxed fit.

Their loose design allows for easy movement, and the quick-drying fabric keeps you comfortable after getting out of the water.

However, the lack of a built-in liner may require wearing swim briefs or compression shorts underneath for added support.

Pros and Cons of Board Shorts for Swimming

• Pros:

  • Comfortable and relaxed fit.
  • Quick-drying, lightweight fabric.
  • Versatile for beach activities and casual wear.
  • Stylish, surf-inspired designs.

• Cons:

  • No built-in support, which may feel uncomfortable during active swimming.
  • Longer length and loose fit create drag, reducing swimming speed.
  • Not suitable for competitive swimming or lap swimming.

Board shorts are best for leisurely swimming and beach activities. If you need more support, consider wearing compression shorts underneath.

Do board shorts create drag while swimming?

Yes, board shorts create more drag compared to fitted swimwear because of their loose fit and longer length.

The extra fabric catches water, slowing you down and requiring more effort to swim.

This makes board shorts less suitable for competitive swimming or lap swimming, where speed and efficiency are important.

Why Do Board Shorts Create Drag?

• Loose Fit: The relaxed design allows water to flow inside the shorts, increasing resistance.
• Long Length: The knee-length style covers more surface area, causing more drag compared to shorter swimwear.
• Extra Fabric: The lightweight, flexible material catches water, creating resistance with each stroke.

While the drag isn’t an issue for recreational swimming, it affects speed and performance in competitive swimming. For better speed, consider fitted swim trunks or jammers.

Are board shorts good for water sports?

Yes, board shorts are excellent for water sports like surfing, paddleboarding, and beach volleyball.

They are designed for active movements, offering flexibility and durability. The quick-drying fabric prevents chafing and discomfort during extended wear.

Their loose fit allows freedom of movement, making them ideal for activities that require agility and balance.

Why Board Shorts Are Great for Water Sports

• Freedom of Movement: The loose fit and flexible fabric allow unrestricted movement.
• Durability: Designed to withstand saltwater, sun exposure, and friction from surfboards.
• Comfort: Quick-drying material prevents chafing and discomfort during extended activities.
• Style: Surf-inspired designs are stylish and functional for beach sports.

For surfing and paddleboarding, the longer length protects the thighs from friction and sunburn. Their versatility makes them a favorite among water sports enthusiasts.

Should you wear something underneath board shorts?

Yes, wearing something underneath board shorts is recommended for comfort and support.

Since board shorts don’t have built-in liners, wearing swim briefs or compression shorts provides support and prevents chafing.

This is especially important for active swimming or water sports³, where extra support is needed for comfort and mobility.

What to Wear Under Board Shorts

• Swim Briefs: Lightweight and supportive, perfect for swimming and water activities.
• Compression Shorts: Provide muscle support and prevent chafing during active movements.
• Swim Jammers: Fitted and supportive, ideal for competitive swimming or lap swimming.
• Nothing (Commando): An option for casual beachwear, but may feel uncomfortable when wet.

Choosing the right undergarment ensures comfort, support, and hygiene. It also prevents wardrobe malfunctions during active swimming or beach sports.

Are board shorts allowed in swimming pools?

It depends on the pool’s dress code, but most public swimming pools allow board shorts as long as they are made of swimwear material.

Some pools have rules against streetwear shorts for hygiene reasons, so it’s best to check the pool’s policy before wearing board shorts.

Avoid wearing cotton board shorts in pools as they absorb water, become heavy, and release fibers that can clog filters.

Pool Rules for Board Shorts

• Allowed: Quick-drying, swimwear-specific board shorts made of polyester or nylon.
• Not Allowed: Cotton or non-swimwear materials, which absorb water and damage pool filters.
• Check the Dress Code: Some pools have strict rules about swimwear style and fabric for hygiene and safety reasons.

To be safe, always check the pool’s guidelines before wearing board shorts. Choosing swimwear-specific board shorts ensures comfort and compliance with pool rules.

Conclusion

Board shorts are suitable for recreational swimming and water sports because of their comfortable, relaxed fit and quick-drying fabric. However, they create drag and lack support, making them less ideal for competitive swimming or lap swimming.

For added comfort and support, wear swim briefs or compression shorts underneath. While board shorts are versatile and stylish for beach activities, consider fitted swim trunks or jammers for better speed and performance in the water.
