Swim trunks are an essential item for any man who enjoys spending time in the water. They come in countless styles, colors, and designs, but one common feature that is often misunderstood is the mesh netting inside the trunks.
In my experience, both as a competitive swimmer and now as a textile expert, I've found this liner is one of the most crucial and underappreciated elements of good swimwear design. If you've ever wondered why men's swim trunks have netting, you're in the right place to find out.
Key Takeaways
- Essential Support: The primary function of the mesh liner is to provide built-in support, similar to an athletic supporter, which is critical for comfort and security during active water sports.
- Chafe Prevention: Netting creates a protective barrier between the skin and the outer fabric, significantly reducing friction and the risk of painful chafing, especially when wet.
- Hygiene and Breathability: The mesh design promotes airflow and allows water to drain quickly, helping the trunks dry faster and preventing the clammy feeling that can lead to skin irritation.
- Improved Fit and Modesty: The liner helps the swim trunks maintain their shape and prevents the outer shell from awkwardly clinging to the body when you get out of the water.
The Four Core Functions of Swim Trunk Netting
That mesh liner isn't just a random addition; it's an engineered feature with several important jobs. Let's break down exactly what it does.
| Function | Benefit |
|---|---|
| Support and Comfort | The netting acts as a built-in brief, providing crucial support. This is especially important for men who engage in dynamic water activities that require a lot of movement, such as swimming, diving, or surfing. It helps keep everything in place and prevents the trunks from riding up or shifting uncomfortably. |
| Protection from Chafing | A quality mesh liner provides a soft, protective layer for the skin. As a former athlete, I know how debilitating chafing can be. The netting prevents friction between your skin and the coarser outer fabric, a common issue that, according to the American Academy of Dermatology Association, is worsened by moisture and irritating fabrics. |
| Hygiene and Airflow | In addition to support, the netting promotes better hygiene. Its porous structure allows for excellent airflow and drainage, which helps the area dry faster. This reduces the risk of bacterial growth or other harmful substances from prolonged contact with damp skin. |
| Improved Drape and Design | From a design perspective, the netting helps the outer shell of the swim trunks drape more naturally. It prevents the fabric from clinging awkwardly to the body when wet, ensuring a more flattering and comfortable fit both in and out of the water. |
Myth vs. Reality
Myth: "The netting is uncomfortable and useless, so you should just cut it out."
Reality: This is one of the most common mistakes people make with swim trunks. As a textile engineer and lifelong athlete, I can assure you that removing the liner defeats the entire purpose of the garment's design. Without it, you lose all support, leading to discomfort. More importantly, you expose your skin directly to the wet outer fabric, which dramatically increases the risk of severe chafing. The liner is the functional core of the swim trunks; removing it leaves you with just a baggy, inefficient pair of shorts.
So, Should You Choose Swim Trunks with Netting?
Ultimately, the netting inside men's swim trunks is a carefully considered feature that serves several vital purposes. It's engineered to provide support, comfort, protection, and hygiene.
Whether you're a seasoned swimmer or just looking to enjoy a day at the beach, my professional recommendation is to always opt for well-designed swim trunks with high-quality netting. It’s a small detail that makes a world of difference in your comfort and confidence in the water.

Frequently Asked Questions
Q1: Is it okay to cut the netting out of men's swim trunks?
While it's a personal choice, we generally advise against it. Cutting out the mesh liner removes all the built-in benefits, such as support, chafe protection, and breathability. This can lead to discomfort, irritation, and a less flattering fit, especially when the trunks are wet.
Q2: What is the netting in swim trunks usually made of?
The netting, or mesh liner, is typically made from lightweight, breathable, and quick-drying synthetic materials like polyester or nylon. These fabrics are chosen for their ability to manage moisture and provide soft, flexible support without becoming heavy or waterlogged.
Q3: How can I prevent chafing from swim trunk netting?
To prevent chafing, ensure your swim trunks fit correctly—not too tight or too loose. Rinse your trunks with fresh water after swimming to remove salt and chlorine, which can irritate the skin. If you're prone to chafing, you can also apply an anti-chafe balm to sensitive areas before heading to the beach or pool.
Q4: Do all men's swim trunks come with netting?
No, not all styles do. Traditional swim trunks and board shorts almost always feature netting for the reasons mentioned above. However, shorter, more athletic styles like swim briefs or jammers are designed to be form-fitting and do not require an internal mesh liner for support.
Q5: Should I wear underwear with swim trunks that have netting?
No, you should not wear underwear under swim trunks with a mesh liner. The netting is designed to provide all the necessary support and breathability, effectively acting as a built-in undergarment. Wearing cotton underwear underneath will trap water, slow down drying time, and can actually increase the risk of chafing and bacterial growth.
