Is It Necessary To Wear Underwear While Running

As a seasoned runner, I often ponder the question of whether it is necessary to wear underwear while running. The topic may seem trivial at first, but it’s a question that many runners contemplate. Let’s delve into the debate and explore the various factors to consider when making this decision.

Comfort and Chafing

The first consideration when deciding whether to wear underwear while running is comfort. Some runners prefer the support and coverage that underwear provides, while others find it restrictive and opt to go commando. Personally, I have experienced the discomfort of chafing during long runs, and for me, a good pair of moisture-wicking, seamless underwear has been a game-changer in preventing chafing in sensitive areas.

Hygiene and Moisture Management

Another aspect to ponder is hygiene and moisture management. High-quality running underwear is designed to wick moisture away from the body, keeping you dry and reducing the risk of chafing and irritation. However, some runners argue that wearing underwear traps sweat and heat, which can lead to discomfort and even increase the risk of infections. It’s crucial to find a balance and choose underwear made of breathable, moisture-wicking fabric to maintain good hygiene without sacrificing comfort.

Apparel and Support

When it comes to choosing running attire, the style of running shorts or tights plays a role in the decision to wear underwear. Some running shorts and tights come with built-in liners designed to offer support and coverage, eliminating the need for additional underwear. In such cases, I find that wearing underwear becomes redundant and can even cause unnecessary bulk and discomfort.

Personal Preference

Ultimately, the decision of whether to wear underwear while running comes down to personal preference. Every runner has their own comfort and hygiene considerations, and what works for one individual may not work for another. It’s important to experiment and find what suits your body and running style best.


In conclusion, the debate on whether to wear underwear while running is a personal one with no one-size-fits-all answer. Comfort, hygiene, and personal preference all play a role in making this decision. As a runner, I have found that investing in high-quality running underwear and considering the factors mentioned above has greatly enhanced my running experience. Whether you choose to wear underwear while running or not, the most important thing is to feel comfortable and confident in your choice.
