Nylon Underwear vs Cotton: Which Is Better? Pros & Cons

Raise your hand if you’ve ever worn uncomfortable underwear. Yup, me too. There’s nothing worse than enduring a whole day in your least favorite pair of panties because you forgot to do the laundry. Except maybe sitting in a pair of undies that retains all your sweat on a scorching hot day, forming a unique aroma that cannot go unnoticed (or so you imagine).

Sometimes a good pair of underwear can truly make all the difference. It can make you feel sexy, or it can simply make you forget about your skin problems down there. Either way, it’s worth it.

If you have sensitive skin, you’re likely wondering whether nylon underwear vs cotton will be better for your needs. And that’s a good question. Join us as we explore all the pros and cons of each fabric and make a detailed comparison that will answer all the questions you have and a few you didn’t even realize you needed to consider. 

What Is Nylon Underwear?

Nylon underwear is made from a synthetic material that is durable, elastic, and smooth in texture. 

This synthetic material is nylon — a man-made polymer. It’s lightweight and absorbent, and it dries quickly, making it a popular choice for lingerie and undergarments. Nylon underwear charms with its sleek and form-fitting design, while also giving you much-needed comfort and support. Plus, it’s quite resistant to repeated washing and wear, making it a long-lasting option for your everyday adventures. 

But the biggest question is, is it better than cotton?

What Is Cotton Underwear?

It’s probably the most popular type of underwear there is. Cotton fabric is light, comfy, and breathable. It feels great for your skin and many gynecologists recommend it for everyday wear. That must mean it’s the best choice, right? Don’t rush to the shop just yet. Nylon underwear has some strong advantages you should consider before making a choice between the two.

Nylon and cotton underwear are both comfortable but feel different on your skin.

Nylon underwear feels silky and lightweight. Also, it stretches and conforms to your body, providing a snug and supportive fit.

In contrast, cotton underwear feels more soft than silky. It’s a good choice for everyday wear. 

Ultimately, whether you find nylon or cotton underwear more comfortable is down to your personal preferences. Some may prefer smooth and form-fitting nylon underwear, while others may opt for the softness of cotton.


Generally, cotton underwear is more breathable than nylon. After all, a natural fiber like cotton provides better air circulation than a synthetic fiber like nylon. The cotton fabric also has a more open weave structure compared to nylon, allowing for better airflow through the fabric. This further helps to regulate your body temperature.

So, is nylon breathable enough for underwear?

While nylon is somewhat breathable, it’s not as breathable as cotton underwear. Nylon fabric tends to trap heat and moisture closer to the skin, leading to a less comfortable experience, especially in warm or humid conditions.

Moisture Control

Cotton naturally absorbs a lot of moisture, such as your sweat, and allows it to evaporate, helping to keep your body dry. Also, this reduces the chances of experiencing discomfort, chafing, and irritation. That’s why people who sweat a lot or love intensive physical activities prefer cotton underwear.

Now, nylon underwear also has moisture-wicking properties, it’s no match for cotton. Plus, nylon fabric may retain moisture, leading to dampness or discomfort, especially if you wear it for extended periods or in a hot environment.

Overall, if moisture control is a priority, cotton underwear is the superior choice. 

Odor Control

So, nylon vs cotton underwear — which is better for odor control? If you’ve been paying attention, you can already guess.

Generally, moisture from sweat contributes a lot to odor buildup. And since cotton is great at absorbing moisture, it also prevents odor-causing bacteria in your underwear. 

On the other hand, nylon panties aren’t as effective at absorbing moisture. They can trap moisture against the skin, creating a lovely environment for some party-seeking odor-causing bacteria.

If you’re concerned about odor from your underwear, cotton is the better choice. It’s super absorbent and breathable, which minimizes odor buildup.

Here’s where nylon wins. Nylon fabric underwear is more durable than cotton. 

Nylon is a synthetic material, which is more resistant to tearing, stretching, and abrasion compared to cotton. This makes nylon underwear less prone to damage from regular wear and washing. So, your nylon briefs will likely stay in your wardrobe a lot longer. 

What’s more, nylon is quite stretchy, which helps it retain its form and fit even after you’ve tried your best to ruin it. The fabric also keeps its color vibrant better than cotton. 

In contrast, cotton fibers can weaken and break down over time, especially with frequent wear. Cotton underwear may also shrink or lose its shape after washing, so you’ll need to buy more sooner than nylon underwear.

Overall, if you want your underwear to last longer and not fade as quickly, nylon panties might be the perfect option for you. 

Maintenance and Care

Even if nylon fabric is more durable, cotton underwear might be easier to care for. 

Cotton pants are usually machine-washable and can withstand regular washing with standard laundry detergents. You can also air- or machine-dry your cotton underwear on a low to medium heat setting without damaging the material. Generally, there’s no need for special treatments or fabric conditioners when washing cotton underwear, making it a low-maintenance option.

On the other hand, nylon underwear may require gentle or delicate cycle washing. Some nylon fabrics may also require special detergent or fabric softener to maintain their softness and elasticity. It’s also essential to air-dry your nylon underpants or at least to use a low-heat setting when machine-drying them. Otherwise, you risk shrinking or deforming them. Finally, nylon underwear stains more easily than cotton, and some stains may be more challenging to remove. 

To sum up, nylon and cotton underwear are relatively easy to care for, but cotton is more forgiving and requires less care, making it a convenient option for everyday wear.

Environmental Impact

While both fabrics are very far from being sustainable, nylon generally has a more significant negative impact on the environment.

Nylon material is made from petroleum-based chemicals. Producing it involves fossil fuels, contributing to water and air pollution and greenhouse gas emissions. It also requires significant energy input and water usage. 

Meanwhile, cotton cultivation requires significant water and land resources, but at least it’s a renewable resource. Still, cotton farming usually involves the use of pesticides, insecticides, and synthetic fertilizers, which can harm the soil, water quality, and biodiversity.

But wait, there’s more. 

Nylon is not biodegradable and stays in the environment for hundreds of years, contributing to plastic pollution in oceans and landfills. Meanwhile, cotton is biodegradable, but farming practices can also contribute to habitat loss due to deforestation for cotton cultivation.

Overall, nylon underwear is worse for the environment than cotton. But to be entirely fair, either fabric is a bad choice if you want to be more eco-friendly. As an alternative, you can also check out how bamboo underwear measures up to cotton

Cost Comparison

Is nylon or cotton underwear better for your wallet? The truth is you can find cheap options for both fabrics.

Still, cotton is a widely available natural fiber that’s relatively inexpensive to produce compared to a synthetic material like nylon. Cotton processing and manufacturing methods are often simpler and less expensive than producing nylon. And since you can find cotton in almost all underwear stores, its cost tends to stay lower (unless you’re after organic cotton). 

So, nylon underwear is more expensive to produce and more limited, meaning it’s also more expensive. 

Nylon Underwear vs Cotton: How to Choose

Choosing between nylon underwear and cotton underwear depends on your personal preferences, needs, and priorities. But if I have to keep it real, unless you absolutely love the silky feel of nylon underwear on your skin, you have no reason to choose nylon underwear. 

Whether you’re looking for breathability, moisture and odor control, easy maintenance, lower environmental impact, or lower cost, cotton underwear is the better choice

Nylon vs Cotton: Which Is Better for Sensitive Skin? 

Cotton underwear is better for people with sensitive skin. It has hypoallergenic properties, breathability, absorbency, and a gentle feel against the skin. If you have sensitive skin, it’s essential to choose underwear made from soft, natural fabrics like cotton and to avoid materials that may cause irritation or discomfort (like nylon).


Is nylon bad for underwear?

Nylon is not bad for underwear, but it’s also not the best choice. Some nylon benefits include durability and moisture-wicking properties, but the fabric can be less breathable and may trap heat and moisture, potentially leading to discomfort or irritation, especially for people with sensitive skin or in hot climates.

Is nylon like cotton?

No, nylon is very different from cotton. Still, both fabrics feel very comfortable on the skin. 

Does nylon absorb sweat?

Nylon might absorb some of the sweat but isn’t the best fabric for moisture-wicking. Cotton underwear does a much better job at absorbing the sweat and preventing any unpleasant odors in your pants. 

Is nylon underwear good for summer?

Nylon underwear can be good for summer, but it’s not the best choice of fabric. It will absorb some of your sweat and will dry quickly, but it’s considerably less breathable than cotton.

Can nylon underwear cause odor?

Yes, nylon underwear can contribute to odor buildup due to its limited breathability, which can trap sweat and bacteria against the skin. While nylon fabric may have moisture-wicking properties, it doesn’t absorb moisture as effectively as cotton, potentially leading to some unpleasant smells.

Is nylon healthy for underwear?

Nylon underwear is generally safe, but it may not be the healthiest option for everyone. While this fabric is durable and moisture-wicking, it can also trap heat and moisture, potentially leading to discomfort, irritation, or bacterial growth, especially for those with sensitive skin.

Is nylon better than cotton?

No, nylon is not better than cotton. While nylon has some minor advantages, like a silky feel and high durability, many other fabrics offer significant benefits. 

Why wear nylon underwear?

Nylon underwear offers an incredibly smooth texture that feels great on the skin. Also, it’s quite a durable fabric. That said, if you care about moisture and odor control, or if you have sensitive skin, cotton underwear is the better choice. 

What are the advantages of cotton underwear over nylon underwear?

The advantages of cotton underwear include a soft and gentle feel, high breathability, moisture and odor control, easier maintenance, and lower cost.
