What To Wear Under Leggings Running

When it comes to running in leggings, the question of what to wear underneath is a common dilemma. As a passionate runner and fitness enthusiast, I’ve experimented with various options to find the perfect combination of comfort, support, and performance. Here’s my take on what to wear under leggings for a successful and enjoyable run.

Consider the Fabric

Before deciding on what to wear under your leggings, it’s essential to consider the fabric of both the leggings and the undergarments. Opt for moisture-wicking, breathable fabrics to ensure that sweat is drawn away from the body, keeping you dry and comfortable throughout your run. In my experience, seamless undergarments made from performance fabrics work best to prevent chafing and maximize flexibility.

Supportive Sports Underwear

For women, a supportive sports bra is a must, even when wearing leggings. Look for a sports bra that provides adequate support and comfort without adding bulk. Seamless, compression sports bras are ideal for minimizing movement and ensuring a secure fit. Personally, I prefer racerback styles for their added support and freedom of movement.

Compression Shorts or Briefs

For both men and women, wearing compression shorts or briefs underneath leggings can offer additional support and reduce friction. Compression shorts provide muscle stability and can aid in reducing muscle fatigue during longer runs. Additionally, they can help prevent chafing and offer a streamlined fit under leggings.

Avoid Cotton

Avoid wearing cotton underwear when running in leggings. Cotton tends to retain moisture, leading to discomfort and potential chafing. Instead, opt for performance-based fabrics designed to keep you dry and cool, even during intense workouts.


Choosing the right undergarments to wear under leggings can significantly impact your running experience. By prioritizing comfort, support, and breathability, you can optimize your performance and maximize your enjoyment of each run. Experiment with different combinations to find what works best for you, and remember that the right choice of undergarments can make all the difference in your running journey.
