Do Men’s Running Shorts Have Liners

When it comes to choosing the right running shorts, there are many factors to consider. One of the most debated aspects is whether or not men’s running shorts should have liners. As an avid runner myself, I have spent countless miles pondering over this question and experimenting with different types of shorts. In this article, I will delve deep into the topic and provide you with my personal insights and recommendations.

To Line or Not to Line?

The first thing you need to understand is that men’s running shorts come in two main varieties: with liners and without liners. Shorts with liners have a built-in underwear-like layer, while shorts without liners are essentially just lightweight fabric without any additional support. The decision to wear lined or unlined shorts ultimately depends on personal preference and specific needs.

One argument in favor of lined shorts is the added support and comfort they provide. The built-in liners offer a snug fit that helps prevent chafing and provides additional support to keep everything comfortably in place during your runs. For those who prefer not to wear additional underwear while running, lined shorts can be a convenient and practical option.

On the other hand, some runners find the liners to be unnecessary and even uncomfortable. They may feel restrictive or cause irritation, especially during long-distance runs or in hot and humid weather. Additionally, liners can sometimes retain moisture and become a breeding ground for bacteria, leading to unpleasant odors.

Considerations for Different Types of Runs

When deciding whether to wear lined or unlined shorts, it’s helpful to consider the type of run you’ll be doing. For shorter, faster runs or interval training, unlined shorts can offer the freedom of movement and breathability you need to perform at your best. On the other hand, for longer runs or trail running where comfort and support are crucial, lined shorts may be the better choice.

Another factor to consider is personal preference and body type. Some runners simply prefer the feel of lined shorts, while others find them restrictive. It’s important to try different options and see what works best for you.

Choosing the Right Shorts

Now that we’ve explored the pros and cons of lined and unlined shorts, let’s talk about how to choose the right pair. Here are some factors to consider:

  1. Material: Look for lightweight, moisture-wicking fabrics that will keep you cool and dry throughout your run.
  2. Fit: Make sure the shorts have a comfortable and secure fit, with an elastic waistband or drawstring to adjust the sizing.
  3. Length: Choose a length that suits your personal preference. Some runners prefer shorter inseams for better mobility, while others prefer longer inseams for increased coverage.
  4. Pockets: If you like to carry essentials like keys or energy gels during your runs, look for shorts with secure pockets.


In the end, the decision of whether to wear lined or unlined running shorts is a personal one. It depends on your individual needs, preferences, and the type of run you’ll be doing. I recommend experimenting with both options to see which works best for you. Remember, the most important thing is to choose shorts that are comfortable, breathable, and allow you to perform at your best. Happy running!
