Is It Weird to Wear Underwear Under Swim Trunks?

Introduction

One common question people have when heading to the pool or beach is whether they should wear underwear under their swim trunks. It might seem like a natural choice to add that extra layer, but is it really necessary? In this article, we’ll address whether it’s appropriate to wear underwear under swim trunks and provide advice on the best practices for staying comfortable while swimming.

Should You Wear Underwear Under Swim Trunks?

In most cases, it’s not necessary to wear underwear under swim trunks. Swim trunks are designed with built-in features to provide comfort and support without the need for an additional layer. Most swim trunks come with an inner mesh lining that serves the same function as underwear, helping to keep everything in place while allowing water to drain easily. Adding underwear can cause discomfort, restrict movement, and interfere with the purpose of the built-in liner.

Why Swim Trunks Don’t Need Underwear

1. Built-In Mesh Lining
  • Why It’s Important: The mesh lining in swim trunks is specifically designed to offer support while allowing for breathability and quick drying. Wearing underwear can trap moisture and lead to irritation.
  • What to Do: Stick to wearing swim trunks as they are. The lining will provide the necessary support and comfort for swimming and water activities.
2. Prevents Chafing
  • Why It’s Important: Underwear under swim trunks can increase the risk of chafing, especially when wet fabric rubs against the skin.
  • What to Do: Avoid wearing an additional layer under your trunks to prevent friction and stay comfortable during extended time in the water.
3. Quick Drying Material
  • Why It’s Important: Swim trunks are made from materials that dry quickly, while most underwear is made from cotton, which holds onto moisture.
  • What to Do: By wearing only your swim trunks, you allow for better airflow and faster drying, preventing any discomfort from prolonged wetness.

Exceptions: When Wearing Underwear Might Be Appropriate

1. Swim Shorts Without Lining
  • Why It’s Important: Some swim shorts are designed without a mesh lining. In these cases, wearing underwear may be more comfortable to provide some support.
  • What to Do: If your swim shorts lack lining, consider wearing moisture-wicking underwear to avoid holding onto water and ensure comfort.
2. Personal Comfort
  • Why It’s Important: Everyone’s comfort level is different. Some people may feel more secure wearing underwear, especially when transitioning between swimming and other activities.
  • What to Do: If you prefer wearing underwear, opt for quick-dry fabrics like compression shorts or athletic underwear to maintain comfort while in the water.

Alternatives to Traditional Underwear

1. Compression Shorts
  • Why It’s Great: Compression shorts provide snug support and are made from moisture-wicking materials, making them an ideal alternative to regular underwear if you want extra coverage.
  • What to Do: Wear compression shorts under your swim trunks for added comfort without the drawbacks of traditional cotton underwear.
2. Swimsuit Briefs
  • Why It’s Great: Swimsuit briefs are specifically designed for swimming, offering both support and quick-drying capabilities.
  • What to Do: Use swimsuit briefs if you want additional support under your swim trunks without sacrificing comfort in the water.

Conclusion

Wearing underwear under swim trunks is generally unnecessary and can lead to discomfort, especially when the fabric gets wet. Swim trunks are designed with built-in support and quick-drying materials, making them suitable for water activities on their own. However, if your swim shorts lack lining or you prefer additional support, opt for moisture-wicking alternatives like compression shorts or swimsuit briefs. Ultimately, it comes down to personal preference, but for most people, swim trunks work best as they are designed.
