Should I Wear Underwear Under Running Shorts

When it comes to running shorts, one question that often arises is whether or not to wear underwear underneath. As a seasoned runner myself, I can confidently say that this decision is entirely subjective and depends on personal preference. However, there are a few factors to consider before making your choice.

The Case for Wearing Underwear

Wearing underwear under running shorts can provide an extra layer of protection and support. Many runners find that the added fabric can help prevent chafing and irritation, especially on long-distance runs. Additionally, the right pair of underwear can offer additional moisture-wicking properties, keeping you dry and comfortable throughout your run.

For male runners, wearing supportive underwear can also provide much-needed stability and reduce the risk of discomfort or injury. Compression shorts, for example, can offer added support to the muscles and help improve performance during intense workouts or races.

The Argument Against Underwear

On the other hand, some runners prefer to go commando and skip the underwear altogether. This choice allows for increased ventilation and freedom of movement, which can be particularly beneficial during hot and humid runs. Additionally, by eliminating the extra layer of fabric, there is less risk of chafing or discomfort.

Furthermore, many running shorts are designed with built-in liners or briefs that provide sufficient support and coverage. These liners are often made from moisture-wicking material, reducing the need for additional underwear. If your shorts have a built-in liner, you may find that wearing underwear is unnecessary and only creates unnecessary bulk and discomfort.

My Personal Recommendation

As someone who has experimented with both options, I lean towards wearing underwear under my running shorts. I find that the extra layer of protection and support gives me added confidence and prevents any potential discomfort. However, I understand that everyone’s body is different and what works for me may not work for everyone.

If you’re unsure which option to choose, I recommend trying both and seeing what feels most comfortable for you. Pay attention to any signs of chafing or discomfort and adjust accordingly. Remember to choose moisture-wicking and breathable fabrics for both your shorts and underwear to keep you cool and dry during your runs.


Ultimately, whether or not to wear underwear under your running shorts is a personal decision that depends on your individual preferences and needs. Take into consideration factors such as comfort, support, and the design of your shorts before making your choice. Remember, the goal is to feel confident, comfortable, and free to focus on your run without any distractions or discomfort.
