Best Underwear When on Period: 8 Leak-Proof Lifesavers for Every Flow

Ugh, periods. They can be such a pain, especially when you’re worried about leaks. That constant nagging fear of an embarrassing moment is all too familiar. After testing over 40 pairs of period underwear, I’ve got the scoop on the best ones out there.

This article will guide you through top picks for every flow and budget. Ready to kiss those period worries goodbye and feel more comfortable during that time of the month? Let’s dive in and find you some game-changing undies. ³

What is Period Underwear?

Period underwear is a game-changer for that time of the month. It’s like your favorite comfy undies, but with superpowers to catch leaks and keep you dry.

Absorbency Levels Explained

I’ve tried many period products, and let me tell you, absorbency levels in period underwear are a game-changer. These undies come in different soaking powers, just like tampons. Light, medium, heavy – you name it, they’ve got it.

But here’s the kicker: there’s no official rule book on how much they can hold. It’s like the Wild West of menstrual gear!

I’ve found that most brands measure their absorbency in tampon equivalents. For example, a “super” pair might hold as much as 2-3 regular tampons. Pretty neat, right? Some even go up to 5 tampons worth! ¹ It’s not just for periods, either.

These magic undies can catch discharge, help with bladder leaks, or even postpartum bleeding. Talk about multitasking! Now, let’s dive into the comfy world of period underwear materials.

Finding the right absorbency level is like finding the perfect pair of jeans – it takes some trial and error, but once you do, it’s life-changing!

Comfort and Material Options

I love how period underwear has come so far! Gone are the days of scratchy, uncomfortable options. Now, we’ve got choices that feel like a dream. From soft cotton blends to silky modal fabrics, there’s something for everyone.

I’ve tried both nylon or cotton underwear and found that cotton is my go-to for breathability.

But some brands use fancy materials like Tencel that wick moisture away quickly. It’s not just about the fabric, though. The cut matters too. You can find everything from cute bikinis to full-coverage briefs that make you feel secure and comfy. ²

Let’s talk about absorbency levels next. It’s a game-changer for period undies!

Available Styles

Now that we’ve covered comfort and materials, let’s talk styles. Period underwear comes in all shapes and sizes. You’ll find everything from cute bikinis to full-coverage briefs. I’ve even seen boxer shorts for those who want extra protection.

Some brands offer high-waisted options that smooth your tummy. Others have sexy lace trims for a more feminine look. There’s no need to sacrifice style for function anymore. Thinx, for example, has a retro Hi-Waist style that holds up to five tampons’ worth. ³ It comes in sizes XS to 4XL, so there’s something for everyone. If you prefer more coverage, check out Aisle’s Boost Boxer. It can hold more than two tampons and comes in sizes XXS to 5XL.

Care Tips for Period Underwear

Keeping your period undies in tip-top shape isn’t rocket science. I’ll spill the beans on how to make ’em last longer and stay fresh as a daisy.

Cleaning Techniques

I’ve learned a trick or two about keeping my period undies fresh. First things first: I rinse ’em in cold water right after use. I keep at it until the water runs clear. This stops stains from setting in.

Trust me, it’s a game-changer!

For washing, I toss them in the machine on a gentle cycle. It’s kinder to the fabric and keeps ’em in top shape longer. Once they’re clean, I skip the dryer. Instead, I hang ’em up to air dry.

It might take a bit longer, but it’s worth it. My undies last way longer this way. Plus, it saves on energy bills – win-win! ¹⁹

Keeping Absorbency Effective

I’ve learned a few tricks to keep my period underwear working like a charm. First, I always rinse them in cold water right after use This stops stains from setting in. ²⁰ Then, I toss them in the wash with my regular clothes – no special detergent needed! I avoid fabric softeners, though.

They can mess with the absorbent layers. Air-drying is best, but a low-heat tumble dry works in a pinch.

To really max out the life of my period undies, I rotate between a few pairs. This gives each one time to fully dry and bounce back between uses. I also check the fabric for any wear and tear.

If I spot any holes or loose threads, it’s time for a new pair. By taking good care of them, I’ve found my period underwear stays super effective month after month. ²¹

Addressing Health Concerns with Period Underwear

Let’s talk about health and period underwear. Some folks worry about chemicals, but I’ve got the scoop on staying safe and comfy.

Chemical Concerns: PFAS in Period Underwear

I’ve got some news about period underwear that might surprise you. Back in January 2020, Sierra magazine found something called PFAS in Thinx products. ²² PFAS are “forever chemicals” that don’t break down easily.

This discovery led to a big lawsuit against Thinx. By the end of 2022, several lawsuits merged into one big class-action case. ²²

Now, you might be wondering what this means for you. Well, it’s made me think twice about the materials in my period underwear. I’ve started looking more closely at the fabrics used, like nylon vs cotton.

It’s not just about comfort anymore – it’s about safety too. I’m keeping an eye out for brands that are open about their materials and testing. After all, what we put next to our skin matters, especially during that time of the month. ²³

Ensuring Sanitary Safety

I’m all about keeping things clean down there. Period underwear is great, but we gotta make sure it’s safe too. Here’s the scoop: wash ’em after each use with cold water and mild soap.

No fabric softeners! They mess up the absorbency. Hang ’em to dry – it’s key for killing germs. Don’t toss ’em in the dryer, it’ll wreck the special fabric. ²⁴

Let’s talk bacteria. Some folks worry about it, but period undies are actually pretty safe. They’re designed to wick moisture away, which stops nasties from growing. Just change ’em every 4–6 hours, like you would a pad.

And if you’re extra worried, give ’em a pre-rinse before tossing in the wash. Easy-peasy! ²¹
