When heading to the beach, pool, or any water-related activity, choosing the right attire is essential for comfort and confidence. One of the most important yet often overlooked aspects is what to wear underneath your swim shorts. The right undergarment can enhance comfort, prevent chafing, and even improve your overall look. With a variety of options available, knowing what works best for your body type and activity can make all the difference. In this guide, we’ll explore the best choices for men’s underwear or liners to wear under swim shorts, helping you feel your best every time you hit the water.

What to Wear Under Swim Shorts Men


Understanding Your Options: Types of Underwear and Liners for Swim Shorts

Choosing the right undergarment for your swim shorts depends on comfort, functionality, and personal style. Here are the primary options available:

  • Built-in Mesh Liners: Most modern swim shorts come with a mesh liner sewn into the interior. These liners provide support, prevent chafing, and eliminate the need for separate underwear during water activities.
  • Swim Briefs or Swim Trunks: If your shorts lack a liner or you prefer more support, wearing swim briefs or speedo-style trunks underneath can be a good choice.
  • Boxer Briefs: Designed specifically for swimming, some men opt for lightweight boxer briefs made from quick-drying materials for extra coverage and support.
  • Compression Shorts: These are tight-fitting and offer excellent support, especially useful for active water sports like surfing or swimming laps.
  • Regular Underwear: It’s generally not recommended to wear everyday underwear under swim shorts, as they tend to retain water, cause chafing, and are not designed for aquatic environments.

Why Most Men Use Built-in Mesh Liners

Many swim shorts come with a built-in mesh liner because it offers a perfect balance of support, comfort, and convenience. Here are some reasons why mesh liners are popular:

  • Support and Security: Provides gentle support, preventing accidental exposure or discomfort during active movement.
  • Comfort: The breathable mesh helps reduce chafing and keeps you comfortable throughout your water activities.
  • Hygiene: Built-in liners are easier to wash and maintain, reducing the need for additional layers or underwear.
  • Convenience: Eliminates the need to wear separate underwear, simplifying your swimwear choices.

However, some men prefer to wear additional or different types of undergarments depending on their comfort level and the activity planned.


Should You Wear Underwear Under Swim Shorts?

In most cases, wearing traditional underwear under swim shorts is not recommended. Here are some considerations:

  • Water Retention: Regular underwear tends to absorb water, becoming heavy and uncomfortable.
  • Chafing and Irritation: Cotton and other fabrics used in everyday underwear can cause chafing when wet or dry.
  • Hygiene Concerns: Underwear not designed for aquatic use may trap bacteria or make drying difficult.
  • Support and Fit: Underwear may not provide the support needed during vigorous water activities and can shift or bunch up.

Therefore, it’s best to rely on the built-in liners or specialized swimwear options rather than regular underwear.


Choosing the Right Support for Water Activities

Depending on your activity level and comfort preferences, different support options may suit you better:

  • Casual Swimming or Beach lounging: Mesh-lined swim shorts are typically sufficient.
  • Active Sports (surfing, snorkeling, swimming laps): Consider compression shorts or swim briefs for maximum support.
  • Longer beach days or sunbathing: Loose-fitting swim trunks with built-in liners offer comfort and style.

Always prioritize quick-drying fabrics and proper fit to avoid discomfort and chafing during prolonged wear.


Materials Matter: What to Look for in Swimwear Underwear

When selecting what to wear under your swim shorts, material choice is crucial for comfort, durability, and hygiene. Here are the common fabrics used:

  • Polyester: Lightweight, durable, and quick-drying. Commonly used in swimwear liners.
  • Nylon: Similar to polyester but softer; offers excellent stretch and quick-drying properties.
  • Spandex/Lycra/Elastane: Provides stretch and shape retention, ensuring a snug fit.
  • Mesh: Breathable and quick-drying, ideal for liners and support layers.

Look for combinations like polyester/spandex or nylon/spandex for optimal performance and comfort. Avoid cotton or heavy fabrics that retain water and cause discomfort.


Additional Tips for Comfort and Confidence

  • Proper Fit: Ensure your swimwear and any undergarments fit well—neither too tight nor too loose—to avoid chafing and unwanted movement.
  • Hygiene: Rinse your swim shorts and any undergarments thoroughly after swimming to prevent bacteria buildup and prolong their lifespan.
  • Layering: If you feel more comfortable with an extra layer, opt for a seamless, quick-drying, and lightweight option designed for water use.
  • Style and Personal Preference: Whether you prefer minimal support or more coverage, choose options that make you feel confident and comfortable.

Conclusion: The Best Choice for Underneath Your Swim Shorts

In conclusion, the most practical and comfortable choice for what to wear under men’s swim shorts is typically the built-in mesh liner that comes with most swimwear. It provides support, hygiene, and convenience without the drawbacks of regular underwear. If additional support is desired, consider wearing swim briefs or lightweight, quick-drying compression shorts specifically designed for aquatic activities. Avoid traditional underwear, as it often retains water, causes chafing, and is not suited for swimming environments. Ultimately, your choice should prioritize comfort, support, and suitability for your specific water activity. By selecting the right undergarments, you’ll ensure a more enjoyable, comfortable, and confident experience at the beach or poolside.
