Popular Styles of Men's Swim Trunks

Classic Swim Trunks

Classic trunks generally have a relaxed fit and may include an elastic waistband or drawstring.

They can work well for:

  • Swimming
  • Beach trips
  • Pool parties
  • Resort vacations

Short Swim Trunks

Shorter trunks have a higher leg opening and typically provide a more compact silhouette.

They can appeal to people who prefer greater freedom of movement and a less traditional board-short appearance.

Board Shorts

Board shorts are generally longer and often have a more structured waistband.

They are commonly associated with:

  • Surfing
  • Beach activities
  • Water sports
  • Casual coastal wear

Novelty Swim Trunks

Novelty designs emphasize the print or graphic.

Examples can include humorous artwork, unusual patterns, food themes, animals, retro graphics, or other playful concepts.

Choosing the Right Fit

Fit can make a major difference in comfort.

Consider:

  • Waist measurement
  • Inseam length
  • Leg opening
  • Rise
  • Overall cut
  • Liner design

A pair that is too tight can restrict movement, while an overly loose pair may feel uncomfortable during swimming.

The ideal fit depends on personal preference and intended activity.

Swim Trunk Materials

Common materials include:

Polyester

Polyester is widely used for swimwear because it is durable and can dry relatively quickly.

Nylon

Nylon is lightweight and commonly used in swim shorts and board shorts.

Polyester-Nylon Blends

Blended fabrics can combine characteristics of both materials.

Stretch Fabrics

Some swimwear incorporates elastane or similar fibers to provide additional flexibility.

The best fabric depends on whether the trunks are primarily intended for swimming, beachwear, or casual use.

Lined vs. Unlined Swim Trunks

Some men's swim trunks include an internal liner, while others do not.

Lined Trunks

A liner can provide additional coverage and support.

Common liner materials include mesh and stretch fabrics.

Unlined Trunks

Unlined designs can provide a different feel and may appeal to people who prefer less internal material.

The choice is largely based on personal comfort and the construction of the particular garment.

Waistband Features

A good waistband can improve comfort and security.

Common features include:

  • Elastic waistband
  • Drawstring
  • Button closure
  • Velcro fly
  • Combination waistband

Drawstrings can be particularly useful when swimming because they allow the waist to be adjusted.

Pockets

Pockets can be useful when swim trunks are worn outside the water.

Common configurations include:

  • Side pockets
  • Back pockets
  • Zipper pockets
  • Mesh pockets
  • Cargo-style pockets

For swimming, excessive pocket material can add bulk or retain water.

Quick-Drying Swim Trunks

Quick-drying materials can be useful for beach and pool activities.

A quick-drying pair can reduce the amount of time the fabric remains wet after swimming.

Drying performance depends on:

  • Fabric composition
  • Fabric thickness
  • Lining
  • Humidity
  • Air circulation
  • Direct sunlight

Swim Trunks for Pool Parties

Novelty swim trunks can be particularly suitable for casual pool parties where playful clothing is appropriate.

Bold prints can include:

  • Tropical patterns
  • Fruit designs
  • Cartoon-inspired graphics
  • Animal motifs
  • Geometric patterns
  • Humorous illustrations

The appropriate design depends on the setting and dress expectations.

Swim Trunks for Beach Vacations

For beach vacations, versatility can be useful.

A pair of swim trunks may be worn for:

  • Swimming
  • Walking along the beach
  • Poolside activities
  • Casual resort activities

A comfortable waistband, practical pockets, and quick-drying fabric can make a pair more versatile.

Swim Trunks for Resort Wear

Some swim trunks are designed to transition between water activities and casual resort settings.

Features such as:

  • Clean patterns
  • Secure pockets
  • Comfortable liners
  • Adjustable waistbands
  • Moderate-length cuts

can make them easier to wear beyond the pool.

How to Choose a Bold Design

A playful swim-trunk design does not necessarily need to be extremely elaborate.

Popular approaches include:

Bold Prints

Large patterns can create a more noticeable appearance.

Subtle Humor

Smaller graphics or understated patterns can provide a playful element without dominating the entire outfit.

Novelty Themes

Food, animals, tropical imagery, and retro designs can create distinctive swimwear.

Bright Colors

Bright colors can provide a more energetic summer appearance.

Swim Trunks and Body Comfort

Comfort should remain a priority when choosing swimwear.

Consider:

  • Soft seams
  • Waistband construction
  • Liner material
  • Leg opening
  • Fabric weight
  • Stretch
  • Chafing potential

Trying different cuts can help determine which construction provides the most comfortable fit.

Swim Trunks for Different Body Types

There is no single swim-trunk style that works for everyone.

Slim Builds

Shorter or tailored cuts can create a balanced silhouette.

Athletic Builds

Many different cuts can work, depending on preferred coverage.

Larger Builds

A comfortable waistband and slightly longer cut may provide additional comfort.

Tall Builds

Longer inseams can provide balanced proportions.

The most important factor is accurate sizing rather than following a fixed rule based on body type.

Checking the Size Chart

Sizing can vary significantly between brands.

Before purchasing, compare:

  • Waist measurement
  • Hip measurement
  • Inseam
  • Outseam
  • Size conversion

A manufacturer's own size chart is generally more useful than assuming the same size will fit across every brand.

How to Care for Swim Trunks

Proper care can help extend the life of swimwear.

After swimming:

  1. Rinse the trunks with fresh water.
  2. Remove excess water gently.
  3. Allow them to dry completely.
  4. Follow the garment's washing instructions.
  5. Avoid excessive heat unless the care label permits it.

Chlorine, salt water, sunscreen, and prolonged sunlight can affect some fabrics over time.

Swim Trunks and Chlorine

Frequent pool use can expose swimwear to chlorine.

To help preserve the fabric:

  • Rinse after swimming
  • Avoid leaving wet trunks in a closed bag
  • Follow washing instructions
  • Allow the garment to dry thoroughly

Some fabrics are specifically designed for greater resistance to chlorine and repeated swimming.

Swim Trunks for Water Sports

If the trunks will be used for surfing, paddleboarding, or other water activities, additional features may be useful.

Look for:

  • Secure waistband
  • Drawstring
  • Flexible fabric
  • Secure pockets
  • Durable construction
  • Appropriate length

The best design depends on the activity.

Common Shopping Mistakes

Choosing a Design Without Checking the Fit

An appealing print cannot compensate for an uncomfortable fit.

Ignoring the Fabric

Fabric affects drying speed, flexibility, durability, and comfort.

Buying Without Checking Measurements

Sizing differs between manufacturers.

Overlooking the Liner

The liner can significantly affect comfort.

Forgetting the Intended Activity

Swimwear for lounging may have different requirements from swimwear intended for active water sports.

Ignoring Care Instructions

Improper washing or drying can shorten the useful life of swimwear.

What to Look for Before Buying

A useful checklist includes:

  • Correct waist size

  • Preferred inseam

  • Comfortable liner

  • Suitable fabric

  • Secure waistband

  • Appropriate pockets

  • Quick-drying construction

  • Suitable print

  • Intended activity

  • Care instructions
