Periods aren't one-size-fits-all, which means your period underwear shouldn't be either. Just like you wouldn't reach for the same pad or tampon on a heavy day that you would on a lighter one, your period panties need some variety too.
The beauty of period underwear is that they can be worn day in and day out (just be sure to machine wash cold and hang dry in between uses), so you can start with one pair and build from there. Think of it like building your wardrobe—except this one's designed to handle whatever your period flow throws at you.
Whether you're dealing with day-three drama or those easy breezy carefree last-day vibes, having the right absorbency (and style!) can make all the difference. They also look (and feel) just like regular underwear, but with the added bonus of an absorbent core.
So, let's break down the different absorbency levels of period underwear—and help you find the perfect pairs to keep you comfy and confident through every stage of your cycle.
Light Absorbency (Light Flow)
Light absorbency period underwear has your back by offering you a confident-boosting form of protection during the lighter moments of your cycle. Absorbing about 1-3 tampons' worth, they're your go-to for minimal coverage without sacrificing comfiness and support.
Here's what they're perfect for:
Spotting Days: Think of these undies as an alternative to wearing panty liners. Worn solo, this level of absorbency works great for the beginning or end of your period when your menstrual flow is light or tapering off. What we recommend: Light Leakproof No-Show Mesh High Rise
Backup Protection: On heavier days of your cycle, you can pair these with tampons or menstrual cups for extra security, stopping unexpected leaks in their tracks. What we recommend: Light Leakproof No-Show High Rise
Non-Period Days: For occasional discharge or sweaty gym sessions, these will keep you fresh and dry throughout the day. What we recommend: Light Leakproof No-Show Thong
Moderate Absorbency (Medium Flow)
Absorbing about 2-3 super tampons' worth, medium absorbency period undies are designed for reliable protection during (can you guess?) moderate flow days (ding ding ding). These are great tools in your period-flow-management toolbox.
Here's what they're perfect for:
Regular Flow Days: When you're mid-period and the flow is steady but not heavy, you can wear these solo for reliable and (comfy) protection. And that's all without the need of a pad or tampon, since they're designed to be worn solo for long stretches of time. What we recommend: Leakproof UltraThin No-Show Bikini
All Day Wear: Useful for a crammed work or school day, so you can knock everything off your to-do list without worrying about when you need to change your pad or tampon. What we recommend: Leakproof Cotton High Rise
Active Days: Comfortable for light workouts or a busy day with lots of outings—a pair of these undies offers you leak protection for all the ways you move! What we recommend: Leakproof Cotton Bikini
High Absorbency (Heavy Flow)
Heavy flow days call for full coverage protection, and high-absorbency period panties are always up for the challenge. With extra coverage and capacity (about 3-6 super tampons worth!), you can feel secure no matter how busy your day gets.
Here's what they're perfect for:
Heavy Flow Days: Use during the heaviest part of your cycle for peace of mind, so you can go about your day without worrying about leaks or frequent pad or tampon changes. What we recommend: Super Leakproof No-Show French Cut
Overnight Protection: This level will keep you leak-free while sleeping without needing additional products (tampons at night = 🚫). No stained sheets? Sounds like a dream! What we recommend: Super Leakproof Dream Short
Travel Days: A+ on long flights or road trips where changing frequently isn't the most practical, these ensure you stay comfy and protected during the long haul… literally. What we recommend: Super Leakproof No-Show High Rise
Ultra Absorbency (Overnight, Extra Heavy Days, or Bladder Leaks)
When maximum protection is 100% non-negotiable (been there), ultra absorbency Leakproof underwear deliver. From postpartum leaks to heavy overnight needs, these menstrual underwear have an extra long protective area that's designed to handle the most intense days with ease—with the ability to hold about 7-9 super tampons.
Here's what they're perfect for:
Postpartum Use: Excellent for postpartum bladder leaks or heavier flows, providing a ton of protection during a time when the ease of comfortable period underwear are especially important. What we recommend: Ultra Leakproof Zones+ High Rise
Heavy Overnight Protection: Provides heavy duty coverage for those with very heavy flows, allowing you to sleep soundly without worrying about leaking over your pjs or your sheets. If you're used to using pads overnight, you can also ditch the disposable menstrual products and opt for Ultra Leakproof reusable pads. What we recommend: Reusable Leakproof Pads - Overnight
Light Bladder Leaks: Sneeze with ease knowing it won't become an emergency situation. Whether you're experiencing menopausal or postpartum incontinence, or anything in between, Ultra Leakproof styles are designed with light bladder leaks in mind. What we recommend: Ultra Leakproof Zones+ Bikini
