Running shorts that have a liner provide support and protection to runners similar to that of underwear, meaning you don’t have to worry about another piece of clothing during your run.
It might seem like an obvious choice, but sometimes your brain will tell you to wear underpants with a pair of shorts and other times it will say not to. Some people prefer having them while exercising, while others think that they shouldn’t be worn. The bottom line is that it comes down to preference as there are some potential downsides when wearing underwear with a pair of shorts – especially a running pair. For example, the liner in shorts like this tend to be thicker than underwear which can make it slightly irritating for some people during exercise like running.
Running shorts went out of their way to eliminate the need for underwear. They can be worn without, but they were constructed this way on purpose so you could skip wearing them (we all do love a nice breeze). This saves you time and energy – although this is a personal preference! But even if you do decide to wear your undies with these running shorts, there are no underwear police that will call you on it. It’s all about your comfort level…so we hope we helped shed some light in deciding what makes you feel most comfortable during your run today (pardon the pun)!
Are you supposed to wear underwear with running shorts?

The age old question of whether to wear underwear beneath your running shorts or not is one that has people split across the board. It would seem that technically it’s a personal decision in which case the majority of responses were “anything goes, it’s up to you! We just want you to be comfortable” so it’s really up to you whether you do wear any or not! Though if you aren’t sure, a good idea is to try on several different types of shorts and see how they feel.
Few reasons to avoid underwear when running
While some runners prefer to run in their underwear, other avid joggers find it far less comfortable than wearing running shorts or a pair of leggings. Here are a few reasons why you should try going commando while running – no matter which type of shorts you decide to wear today!
Stops chafing
Going commando while you run is important because it prevents unnecessary chafing and friction which in turn reduces your risk of rashes on your genitals or around the thighs. Cotton underwear can contribute to infections in this area as well. Wearing skin-tight pants or shorts means that not wearing undergarments will be very comfortable.
Increased hygiene
It’s important to invest in some good quality underwear for your running routine. Cotton is not a great fabric for this as it does not allow moisture to evaporate as quickly, meaning that sweat can linger and lead to chafing and blistering. This can happen especially with women who are prone to yeast infections. So try switching it up and opting for more natural fabrics like bamboo or buy a pair with the right level of elasticity, such as light spandex, so they stay in place while you run longer distances to help keep you cool and fresh throughout your workout. The looser your shorts the better it is for reducing their chances of coming into contact with your skin – something you’ll want to avoid in order to prevent any unwanted pain!
Improved breathability
Running can be sweaty and it’s important to find clothes that provide airflow when exercising. The easiest way to keep cool is by shedding layers of clothes like with shorts and leggings, or allowing the breeze through your clothing will keep you cool while running.
What type of underwear to wear with sports shorts?

Out of all the types of underpants on the market today, it is imperative to know your health needs. You want to make sure that you’re protected from external invaders such as chafing or sweat absorption and the most important thing is making sure your undies come with the correct sizing so that you don’t risk looking like a stuffed sausage because of your woven boxers riding up your groin. We’ve found that briefs are the best type of underwear to wear when it comes dressing for fitness class because we prefer not falling victim to wedgies or funky necklines, for example!
If you’re looking for the best way to invest your money into something that will last and be a great long-term investment, there are many online sites that have lots of information about whether certain thongs or underwear will be suitable for running. When it comes to this sort of thing, there are so many options to weigh up as well as lots of people interested in what’s going on! So having access to advice from other runners or people who have run in these specific brands can help you make the right decision because you’ll know what will be ideal for you either based on your own personal experience or whether you like a particular brand in general.

Why choose shorts that have built-in underwear?
Wearing just one pair of comfortable underwear under your running shorts is far more convenient than wearing full cut briefs. This way you don’t have to put on running shorts over your boxers or knickers, so you only need to focus on buying a high quality pair of running shorts.
Helps for better breathability
Built-in underwear that is available for men and women is a great option. It allows you to perform your activities freely and keeps your entire body cool the evening through. It also helps keep moisture at bay, allowing ample air to flow in and out of the material keeping your core temperature regulated throughout the night!
Prevent over-layering of fabric.
Many people make the mistake of thinking that an underwear top is actually a shorts top. While these two products may look quite similar, the sports vest is designed entirely differently. It has a thin fabric made to be comfortable and light, so the extra layer might inadvertently lead to you feeling too hot and uncomfortable!
Absorbs moisture
Running is an excellent form of exercise, but if you’re not wearing appropriate gear, that run can take a turn for the worse. Cotton underwear being used underneath running shorts may feel luxurious, but it can also be uncomfortable as it does not do a good job of keeping sweat where it belongs – on your body! Instead, opt for advanced running shorts made with modern fabrics that do a better job of providing a barrier between skin and clothes so you don’t have to worry about chafing.
