Muay Thai is a martial art known for its intense training, powerful strikes, and rich cultural history. When stepping into the ring or training at the gym, the choice of what to wear under your Muay Thai shorts can significantly impact your comfort, performance, and confidence. Many fighters and enthusiasts wonder whether they should wear additional layers beneath their shorts and, if so, what options are best suited for this purpose. In this guide, we'll explore the various choices and considerations to help you make an informed decision about what to wear under Muay Thai shorts.

What to Wear Under Muay Thai Shorts


Understanding the Purpose of Wearing Something Under Muay Thai Shorts

Before diving into specific clothing options, it’s important to understand why you might choose to wear something underneath your Muay Thai shorts:

  • Comfort and Support: Proper undergarments can prevent chafing and provide support during vigorous movements.
  • Hygiene: Wearing a clean layer can reduce sweat absorption directly on your skin, maintaining better hygiene.
  • Modesty and Confidence: Some fighters prefer additional coverage for personal comfort and confidence.
  • Protection: A layer can offer minimal protection from minor impacts or accidental scrapes.

Most fighters find that the choice depends on personal preference, training environment, and the type of shorts they wear. Let’s examine the options available.


Types of Clothing to Wear Under Muay Thai Shorts

1. Compression Shorts

Compression shorts are a popular choice among Muay Thai practitioners for their snug fit and functional benefits:

  • Material: Typically made from spandex or nylon blends that offer stretch and breathability.
  • Benefits: Support muscles, improve circulation, reduce muscle fatigue, and minimize chafing.
  • Hygiene: Easy to wash and keep clean, providing a barrier between your skin and the shorts.
  • Examples: Compression leggings or shorts that extend to mid-thigh or longer.

Most fighters wear compression shorts as their base layer, especially during intense training sessions or competitions.

2. Athletic Underwear

Standard athletic underwear can be suitable, but they often lack the support and fit needed for Muay Thai:

  • Boxer Briefs: Offer good support and coverage, preventing chafing.
  • Briefs: Provide minimal coverage but may lack support during high-impact movements.
  • Boxers: Usually loose-fitting; may shift during activity, leading to discomfort.

If choosing underwear, opt for moisture-wicking, seamless designs to prevent irritation.

3. No Underwear (Going Commando)

Some fighters prefer to wear their Muay Thai shorts directly on their skin for maximum comfort and freedom of movement:

  • Advantages: Less bulk, reduced layers, and increased mobility.
  • Considerations: Ensure your shorts are clean and made of breathable, moisture-wicking fabric.
  • Hygiene Tip: Always wear clean shorts and maintain proper hygiene to prevent infections.

Many experienced fighters and trainers advocate going commando under Muay Thai shorts for optimal performance.


Choosing the Right Material and Fit

When selecting what to wear under your Muay Thai shorts, consider these factors:

  • Breathability: Look for moisture-wicking fabrics like polyester or nylon blends to keep sweat away from your skin.
  • Stretch and Flexibility: Materials should stretch with your movements without restricting mobility.
  • Fit: Tight-fitting compression shorts or underwear should snugly support your muscles and prevent shifting during training.
  • Seam Placement: Seamless or flatlock seams reduce chafing and discomfort.

Additional Tips:

  • Always choose high-quality, sports-specific gear designed for martial arts or high-impact activities.
  • Wash your undergarments regularly to maintain hygiene and prevent skin irritations.
  • Try different options during training to find what feels most comfortable and supportive for you.

Practical Considerations for Different Training Scenarios

Depending on whether you're training in a gym, preparing for a fight, or just practicing, your choice might vary:

  • Training Sessions: Compression shorts or going commando are common for comfort and support.
  • Competitions: Many fighters prefer to wear minimal clothing under their shorts for maximum mobility and confidence. Check competition rules regarding undergarments.
  • Warm-up and Cool-down: Light, breathable underwear can be used during warm-up, but many prefer to remove them during sparring or fighting.

Additional Gear Tips:

  • Always wear clean, moisture-wicking gear to prevent infections.
  • Consider using a cup or groin protector for additional safety during sparring or matches—these are worn over your protective equipment, usually outside the shorts.

Summary: Key Points to Remember

Choosing what to wear under Muay Thai shorts ultimately depends on personal comfort, support needs, and training conditions. Here are the main takeaways:

  • Compression shorts are highly recommended for their support, hygiene, and moisture-wicking properties.
  • Standard athletic underwear can be suitable if it’s moisture-wicking and fits well, but it may lack the support of compression gear.
  • Going commando under Muay Thai shorts is a common choice among experienced fighters for maximum freedom and comfort, provided the shorts are clean and breathable.
  • Always prioritize breathable, moisture-wicking fabrics that support your movements and prevent chafing.
  • Hygiene and regular washing are essential to prevent skin issues and infections.

By selecting the right undergarments or layers beneath your Muay Thai shorts, you can enhance your training experience, boost your confidence, and perform at your best. Experiment with different options to discover what feels most natural and supportive for your unique needs and preferences.
