When you look at panties, you’ll find that most of them have something in common—the pocket (or extra layer of fabric) that’s strategically placed between the leg openings. But what is the pocket in panties for? Simply put, the panty gusset is designed to provide protection and breathability, making your underwear more comfortable and hygienic.

The little pocket in panties is sewn around three edges, with an open seam at one end. While not all panties have this inner lining—most do!—and they’re indeed small, but they offer mighty benefits.

What Is the Pocket in Panties Called?

The small pocket in panties is called a gusset and is designed to reinforce the area while providing additional breathability and moisture protection. Many types of panties have gussets permanently sewn into the crotch area, leaving one side open and creating a pocket. One end is usually left open for manufacturing efficiency, but the gusset would function the same and have the same purpose if all the edges were sewn in.  

Despite looking like a pocket, the gusset pocket in panties doesn’t function like any other type of pocket. This means it’s not meant to be used for storage (no matter the rumors you may have heard!). So stick to keeping your extra cash in your wallet or purse. 

A gusset differs from a liner because the fabric panel is sewn into the underwear for structure, comfort, and hygiene, while a liner is an additional layer or insert designed mainly for absorbency or protection. In many panties, the liner is attached to or layered over the gusset, but the two are not the same.

Fun Fact: The term gusset refers to any triangular, or diamond-shaped, patch of fabric sewn into clothing, but it was believed to be first used in the 13th century to refer to the armpit area in a suit of armor. The function is the same–it reinforces the area for additional protection.

What Is the Pocket in Panties For?

The gusset in women’s panties is designed to provide an added layer while also making it more comfortable. So what is the little pocket in panties for? Let’s take a look at a few of the reasons why women’s panties have a gusset. 

Personal hygiene

The pocket in panties can improve personal hygiene because it is usually made from 100% cotton, making panties more breathable and moisture-wicking. This helps prevent the buildup of sweat and moisture that can lead to feminine hygiene issues and unwanted odor. 

Without a cotton panty gusset, moisture and heat can become trapped against the skin, especially when underwear is made from synthetic fabrics. This lack of breathability may increase irritation, discomfort, and chafing. A properly designed gusset helps create a softer, more breathable barrier.

Comfort

The pocket in women’s panties adds another layer of comfort because it keeps the crotch area dry throughout the day by wicking away moisture. The gusset typically adds additional comfort as a cushion, especially against materials like lace or synthetic clothing fabrics, which can cause friction and discomfort. 

Durability

The gusset in women’s underwear reinforces the crotch area to improve durability. Whether you’re wearing thongs or cheeky panties, the crotch is one of the narrowest areas, making it more susceptible to everyday wear and tear. The pocket in panties helps them last longer, making them less likely to rip or tear. 

Are There Different Types of Pockets in Panties?

You can find several different gusset designs in women’s panties. While many are sewn at both ends to create a second layer of fabric, some panties have one or more seams left open. 

Closed panty gussets

A closed panty gusset is fully sewn into the underwear on all sides. This creates a smooth and secure inner lining. Commonly found in many everyday panties, a closed panty gusset offers added durability and helps keep the gusset flat during wear and washing. Closed gussets can also provide a more polished appearance.

Open gussets

An open gusset may improve airflow and breathability. However, an open gusset is also more prone to wear and tear due to friction, increasing the likelihood of ripping on the seams. Overall, the design of the gusset won’t affect its functionality at all.

Floating gusset

A floating gusset is attached only at certain points rather than being completely stitched down. Typically, it’s stitched at the front and the back, leaving openings on each side. This provides added flexibility and works great with pads and panty liner flaps. Simply slide the flaps of your pad into the open sides of the gusset and safely secure them. 

What’s the Difference Between Cotton vs. Synthetic Gussets? 

Why is there a pocket in panties, and does it matter what material it’s made of? A cotton panty pocket, known as a gusset, is made from breathable natural fibers (typically, 100% cotton). A synthetic gusset, on the other hand, is made from materials like polyester, nylon, or spandex blends. The main difference comes down to breathability and moisture control.

Comfortable women’s underwear usually features a cotton gusset, even if the rest of the underwear is lace, satin, mesh, or polyester.  According to the Cleveland Clinic, 100% cotton is considered the best material for underwear because it is breathable, less likely to irritate, and helps reduce moisture buildup that can contribute to odor, irritation, and bacterial overgrowth. 

Soma’s underwear collection features 100% cotton gussets, creating softer, more breathable panties designed with your comfort in mind. 

Do All Types of Underwear Have Gussets?

Not all types of underwear have gussets. Since the main point of a gusset is to protect by preventing friction and the buildup of moisture, some panties don’t need them. In most cases, panties made with synthetic materials like spandex have a gusset to improve breathability.

Why don’t all panties have gussets?

Many types of panties have gussets because they’re made from synthetic materials that require that additional layer of comfort and moisture-wicking ability. However, panties made from cotton and other natural and breathable materials don’t require a gusset because they’re already breathable.

Some seamless panties may not have a gusset because they’re truly seamless. At the same time, some forms of lingerie come without gussets because it’s a more stylistic choice.

What are the Signs of a High-Quality Panty Gusset?

A well-made gusset can make a big difference in comfort, breathability, durability, and overall hygiene. Since the gusset sits in one of the most sensitive areas of the body, paying attention to its quality can help you choose underwear that feels better and lasts longer. Here are some of the top signs of a high-quality panty gusset:

• Soft, breathable fabric. One of the biggest indicators of quality is the fabric itself. A high-quality gusset is typically made from soft, breathable cotton (ideally 100% cotton) because it helps wick away moisture and promote airflow. 

• Strong, even stitching. Well-constructed stitching helps the gusset stay securely attached through repeated wear and washing. Poor stitching can lead to rubbing, tearing, or the gusset separating over time.

• Proper coverage and placement. A quality gusset should provide full coverage in the crotch area without feeling bulky or too narrow. Gussets that are too small may shift during wear or fail to provide enough protection and comfort. 

• Durability over time. A good gusset should maintain its softness, shape, and breathability even after frequent washing. Durable materials and careful construction can extend the shelf life of panties by helping prevent thinning fabric, seam damage, and loss of elasticity. Investing in well-made underwear often means better long-term comfort and fewer replacements over time.

Other Aspects to Consider When Choosing Panties

Even if you choose breathable cotton panties, you might still want a gusset in them to provide you with additional padding. However, there are many factors to consider when choosing the right panties for you. 

Now that you have the answer to your question, “What is the pocket in women’s panties for?”, here are a few other things to think about when shopping for underwear, such as:

• Fabric types. The type of material your panty's gusset is made from can affect your comfort and personal hygiene. Synthetic blends tend to hold heat and are less breathable than natural materials like cotton, which can generate moisture that affects your personal health and hygiene. 

• Style. Whether you wear thongs, bikini underwear, or boyshorts is your personal preference. However, it’s always beneficial to have multiple styles in your drawer, so you can choose the right pair based on what you’re wearing that day and how comfortable you want to be. For instance, if you’re wearing tight pants or leggings, you might choose no-seam panties or a thong.

• Color. It’s helpful to have a variety of colors in your underwear collection. For instance, if you wear white bottoms, you may not want to wear black panties because they can show through. With a few colors, you can match your outfit depending on whether you’re wearing dark or light-colored clothing. Plus, a pop of color amongst the neutrals can make getting dressed for the day more fun.

• Matchability. For some, matching their bras and underwear makes them feel more confident or put-together. If that’s you, you may want to look to see if there are matching bras when shopping for underwear. Whether you like push-up or t-shirt bras, you should be able to coordinate fairly easily with a little strategic shopping.

Panty Gussets: Frequently Asked Questions 

Why are some panty gussets not sewn shut on one side?

Many women notice that the gusset in their panties has one side left open, creating what looks like a small pocket. This is simply a common technique used to attach the gusset cleanly and efficiently. While it may look unfinished, it’s completely intentional and doesn’t affect the comfort, support, or function of the underwear.

Is the pocket in women’s underwear meant for holding items?

No. Despite the rumors, the pocket in women’s underwear is not designed to hold items. The “pocket” is actually part of the gusset, which is the extra layer of fabric sewn into the crotch area for comfort, breathability, and coverage. Its purpose is all about helping your underwear feel softer and more comfortable throughout the day.

What are the health benefits of cotton gussets in women's underwear?

Cotton gussets are popular because cotton is naturally soft, breathable, and moisture-wicking. This makes it a comfortable choice for everyday wear, especially for those with sensitive skin. Breathable fabrics can help reduce excess moisture buildup, which creates a fresher, more comfortable environment throughout the day.
