What Is That Hole in Boxers Really For?

When you hear the word “boxers,” chances are the first thing that comes to mind is a pair of boxer shorts with an opening toward the front. However, if you look a little closer, you'll notice that there's actually a hole there — and it serves a purpose.

Interested in learning more? TomboyX has you covered. Read on to discover all there is to know about that mystery hole in boxers, including what it is and why it’s there. (We’ll also go over different types of boxers to help you find the perfect pair.)

What Is the Hole in a Pair of Boxers?

The hole in boxers is called a fly, and it’s been around for almost as long as shorts have existed. It's often found in more traditional styles, where the two sides of fabric overlap to form a triangle shape at the end. 


This overlapping section — the fly — has two purposes: It helps keep everything tucked away inside. Additionally, it creates an opening where your anatomy can safely pass through without any chafing or discomfort. It’s sometimes referred to as a fly hole or access hole for this reason. 

Whether the hole is there by design or not will depend on your particular style of boxers. Some manufacturers create them with this feature already built in, while others offer an optional fly (as is often seen in jeans). Either way, having an access point makes taking care of business much easier and more comfortable than pulling down your shorts every time. 


Aside from being practical, boxers with a fly hole have aesthetic benefits too. 

The unique shape gives them an eye-catching silhouette that helps to enhance your figure and make you look fabulous whether you're wearing them alone or under other clothes. Since they're usually made from breathable fabrics like cotton, they're lightweight and comfortable, too — perfect for hot summer days.

That said, no matter how you feel about it, there’s no denying that the fly hole has become an iconic part of boxer shorts over the years. It’s a feature we wouldn't want to be without. So next time you pull on your underwear, take a moment to appreciate this simple but incredibly useful feature — we know we will.

How Do You Pick the Perfect Pair of Underwear?

Now that we’ve solved the mystery of the boxer hole, let’s find your next favorite pair.

Finding the right pair of boxers takes time. Whether they’re for everyday wear or special occasions, there are a few factors to consider when finding the right pair of boxers. Material, fit, and style all need to work together to ensure that you end up with a pair of boxers that fits flawlessly and feels just right.


When it comes to materials, there is a wide range of fabrics available on the market. Cotton is one of the most popular materials for boxer shorts, as it is soft and comfortable against the skin. 

Cotton absorbs moisture easily, so you don't have to worry about feeling sweaty or uncomfortable after wearing them for a long period of time. A few other materials worth considering are silk, nylon, and Spandex — each offering its own unique benefits, such as breathability or stretchiness. 


When it comes to fit, there are several types of cuts available in boxers: regular cut, loose fit, and tailored fit. 

  • Regular cut boxers offer more coverage than other styles and are generally considered more comfortable due to their relaxed fit.
  • Loose-fit boxers are great if you want extra room around your thighs and hips while still maintaining some shape around the waistband.
  • Tailored fit boxers hug closely around your body, providing more definition but not too much. These can be an ideal choice if you’re looking for extra support or want something form-fitting yet comfortable. Form-fitting boxers work super well with leggings or other figure-hugging apparel


Finally, style is a major aspect when picking out the ultimate pair of boxers. From colorful stripes or patterns to subtle pastels or simple block colors — there’s no shortage of choices available! 

Alternatively, if you prefer something sleeker, then boxer briefs might be a better option. Boxer briefs tend to provide extra support thanks to their close fit at a mid-thigh length. This fit gives them a slightly more streamlined look than traditional boxer shorts. 

No matter what kind of style you go for, it comes down to personal preference, so make sure that whatever makes you feel most confident. Even on the cloudiest days, the right underwear can help you feel like you’re walking on sunshine. 

What Are the Different Types of Boxers?

Once you have a better grasp on the materials, fit, and style that you’re after, it’s time to go shopping! Here are some of our favorite types of boxers to consider:

Classic Boxer Briefs

These are your traditional style boxer briefs, usually made of cotton and with an elastic waistband. They combine the form-fitting comfort of briefs with the length of traditional boxers. If you’re looking for underwear that provides maximum coverage and support while still allowing breathability and mobility, boxer briefs are definitely for you!

For the best boxer briefs on the market, we recommend checking out our gender-inclusive inventory here at TomboyX. Our 6-Inch Boxer Briefs are designed with extra soft fabrics and a masculine-inspired silhouette: These undies fit like a dream.

Trunk-Style Boxers

This is a more recent addition to the lineup, with shorter legs that sit just above the thigh so that they don't bunch up in your trousers. They come in a variety of colors and patterns — like our Under the Microscope trunks

Prefer a pair that’s not so bright? We’ve got you covered with trunks in solid colors like Java, Plum, and Black. 

Long-Leg Boxers

These provide extra coverage and support by extending down to the knee. They are ideal for wearing with jeans or trousers in colder climates when you need a little extra warmth below the belt. In onesie season, long-leg boxers make any snow day cozier. Long-leg boxers are also especially handy for sports, gym workouts, and water activities. 

For a pair that’s as cool as your style, we suggest our 9” Boxer Briefs — soft, breathable, and incredibly comfortable. What’s not to love?

Boxer Shorts

These are somewhat similar to boy shorts but feature an elastic waistband — perfect for a casual look around the house. Pair them with our comfy-cozy loungewear and experience true comfort at its finest! 

Performance Boxers

Last but certainly not least, we have performance boxers. These are specifically designed for active wear, made with sweat-wicking fabrics like our deliciously soft TENCEL ™ Modal in Absinthe Green, and longer legs for extra coverage.

For unparalleled comfort and style, we recommend pairing your performance boxers with our activewear bottoms. Whether you’re in the mood to show some skin with a comfy pair of shorts or prefer something with a little more coverage, you can count on us to have just what you need to feel good as you push through your activities.  

Any Tips?

As a matter of fact, we have quite a few! Here are three useful tips to help you purchase boxers:

Tip #1: Comfort

Make sure the boxer shorts fit comfortably and don't pinch or move around too much when walking or doing physical activity. Look out for breathable fabrics that will help keep you cool and dry — even during strenuous workouts.

Not sure which fabrics are best? Although there are many, we recommend TENCEL™ Modal. Made from sustainable beechwood — it’s twice as soft as cotton, temperature regulating, and certified biodegradable. 

Tip #2: Price

It's important to think about your budget when choosing boxer shorts. Pure silk boxers with gold thread seem cool and flashy but are probably not worth breaking the bank over. On the other hand, if a pair of boxers seem suspiciously cheap, they’ll likely disintegrate after a few washes, bringing you back to the shopping drawing board. 

 In this case, investing in a pair of quality boxers is likely your best bet. You’ll still need to replace them regularly, but not so often that you feel like going naked is the next best bet. 

Tip #3: Reviews

Read reviews from other customers who have tried the boxer shorts you're considering — this can help indicate the quality and fit of the boxer shorts before making a purchase. 

Here at TomboyX, we’re B Corp certified, hold OEKO-Tex certification, and use organic and recyclable fabrics in as many designs as possible without compromising quality, comfort, or cost. In other words, we’re big fans of the planet and are doing everything we can to keep it healthy! We’re proud of our high sustainability standards and our customer satisfaction.

So if you're ever wondering what that tiny opening in your boxer shorts is for — now you know!
