thinx period panties Buying Guide
Vote for your favorite pair of period panties in our buying guide!
Do you have trouble finding the perfect pair of period panties? You’re not alone! The vast array of choices on the market can be dizzying, so we’re here to help. In this buying guide, we’ll walk you through the different types of period panties and give you our picks for the best ones.
Before we get started, let’s take a look at the different types of period panties:
1) Full-coverage briefs: These are the most traditional type of period panties. They offer full coverage in the front and back, and they’re great for those who want a little extra protection during their period.
2) Boy shorts: Boy shorts are similar to full-coverage briefs, but they have a more streamlined silhouette and typically ride a little higher on the waist.
3) Hipsters: Hipsters offer less coverage than full-coverage briefs and boy shorts, but they still provide enough protection to make them ideal for periods.
4) Thong: Thongs are not ideal for periods, as they offer very little coverage. However, if you like thongs and don’t mind having to change them more often, they can be a good option during your period.
5) Lace: Lace is a popular choice for period panties because it looks pretty and is also very absorbent.
Now that you know about the different types of period panties, let’s take a look at our picks for the best ones!
1) For full coverage, our top pick is the Lunapads Classic Undies. These panties are made from soft cotton and have an absorbent layer that helps to keep your underwear dry during your period. Plus, they come in a variety of fun colors and patterns!
2) If you’re looking for something a little bit sexier, check out the Modibodi Underwear Vibe lace panties. Made from premium lace, these panties are not only sexy but also highly absorbent. Plus, they come in a variety of colors and patterns to suit your style.
3) If you’re looking for an affordable option, check out these Playtex Briefs with Freshnance technology. These briefs feature built-in deodorant to keep you feeling fresh all day long. Plus, they come in packs of three so you can stock up on them during your period!
How to choose the perfect pair of period panties for you
If you’re like most women, you probably dread your period each month. Between the cramps, bloating and fatigue, it can be hard to feel your best. But one thing that can make your period a little more bearable is wearing the right pair of period panties.
There are a lot of different types of period panties on the market these days, so how do you know which pair is right for you? Here’s a guide to help you choose the perfect pair of period panties for your needs:
- Choose a style that fits your lifestyle.
There are three main types of period panties: disposable, washable and hybrid. Disposable panties are best for women who don’t want to have to deal with the hassle of laundering them. Washable panties are more economical in the long run, but they require regular washing. Hybrid panties offer the best of both worlds – they can be washed or disposed of as needed.
- Consider your Flow type.
Period panties come in three different Flow types: light, medium and heavy. Light Flowperiod panties are designed for women who experience light menstrual flow. Medium Flowperiod panties are designed for women who experience medium menstrual flow, while heavy Flowperiod panties are designed for women who experience heavy menstrual flow. Choose the Flow type that corresponds to your own flow to get the most out of your period panties!
- Select a style that feels comfortable to you.
Not all period panties are created equal – some styles may be more comfortable for you than others. For example, if you don’t like feeling constricted, then avoid briefs-style period panties and opt for something looser instead. On the other hand, if you like having plenty of coverage, briefs-style period panties may be just what you need. So take some time to try on different styles until you find one that feels comfortable and natural on your body.
- Pick a color and design that suits your personality.
Most period panty brands offer a variety of fun colors and designs to choose from, so pick one that reflects your personality! Whether you want something bright and colorful or understated and elegant, there’s sure to be a style that matches your taste.
The best period panties according to real women
Period panties have been on the rise in recent years, as women look for more sustainable and environmentally friendly alternatives to disposable pads and tampons. But with so many different brands and styles of period panties available, it can be hard to know which ones are actually worth buying.
That’s why we asked real women to share their experiences with period panties – from the best brands and styles to avoid, to the ones that they swear by. Here’s what they had to say:
-
Thinx – “I love my Thinx! They’re really comfortable, absorbent, and leak-proof.”
-
Modibodi – “I’ve been really happy with my Modibodi panties. They’re comfortable and keep me feeling dry all day.”
-

5 things you need to know before buying period panties
There’s a lot of talk about period panties lately. And for good reason—they can be a game changer when it comes to your menstrual hygiene routine.
But before you go out and buy a pair (or 10), there are a few things you should know. Here are five tips to help get you started:
- Not all period panties are created equal
Just like regular underwear, period panties come in all shapes and sizes. So it’s important to do your research and find the pair that’s right for you.
Some have absorbent lining while others are made from cloth or other absorbent materials. You may also want to consider whether you want pads built into the panties or if you’d prefer to use reusable pads instead.
- They can be expensive
Period panties don’t come cheap. But if you think about it, they’re really an investment in your health. And considering how many pairs you might need, they could end up being cheaper in the long run than disposable pads or tampons.
- They need to be replaced often
Just like any other piece of clothing, period panties need to be replaced often. The lining will eventually wear out and become less effective at absorbing blood and fluid. So be sure to keep an eye on the expiration date and replace them when necessary.
- You still need to use feminine hygiene products
Even though period panties can absorb a fair amount of blood and fluid, they’re not a replacement for traditional feminine hygiene products like pads and tampons. You should still use these products when needed, especially during your heaviest flow days.
- They can be uncomfortable at first
Like anything new, donning a pair of period panties for the first time can feel a bit strange. But with a little bit of patience, you’ll get used to them and likely find that they offer a lot of comfort and relief during your menstruation cycle

Why should I wear THINX period panties?
If you’re like most people, you probably think of tampons and pads when you think of period underwear. However, a new kind of period panties has been making headlines lately: THINX. So, how do THINX period panties work?
First and foremost, THINX are made of 100% cotton and are designed to prevent leaks. They come in a variety of styles, including boy shorts, hiphuggers, and thongs. Additionally, they come in four levels of absorbency: light, regular, heavy, and post-partum.
Here’s how they work: the panties have a thin layer of patented QuikWik fabric that quickly absorbs liquid. The fabric also has antimicrobial properties to keep you feeling fresh all day long. Additionally, the fabric is moisture-wicking, which means it will pull sweat and other moisture away from your skin to keep you feeling dry.
THINX are also helpful for people with light periods or those who just want to wear them as a backup on their heavier days. And if you have a post-partum bleed, THINX can help too!
What are the benefits of wearing THINX period panties?
Period panties are a great way to avoid leaks and stains during your period. They’re also comfortable and absorbent, which means you can wear them all day long without having to worry about your underwear.

They also come in a variety of styles and colors, so you can find the perfect pair for your needs.
THINX panties aren’t just for women with periods. They’re also great for post-menopausal women and those who experience urinary incontinence. If you’re looking for a comfortable and absorbent alternative to traditional underwear, THINX panties are a great option.
Will THINX period panties work for me?
There are plenty of benefits to wearing THINX panties during your time of the month! Not only do they help to reduce the amount of blood that soils your clothes, but they’re also leak-proof and made from antimicrobial materials that prevent bacteria build-up.
THINX panties are perfect for women who lead active lifestyles. Whether you’re a runner, a CrossFitter, or just like to stay active throughout the day, THINX will keep you feeling comfortable and confident.
Another great benefit of THINX panties is that they can be worn overnight. This means that you can go to bed without having to worry about staining your sheets with blood. Plus, as an added bonus, using THINX at night can help to reduce the amount of PMS cramps you experience!
