Goat Union Overnight Period Underwear for Women - Absorbent Period Panties Heavy Flow

Product Information

These period briefs are advertised as holding up to three teaspoons’ worth of liquids, but our tester found that the gusset can hold up to five. Our tester found no leaks or dampness on the outside of the gusset, earning this pair a perfect 5 for absorbency. While some period underwear should be reserved for your lighter days, these may be able to withstand heavier flows. Rael Period Underwear easily absorbed three tampons' worth of liquid during testing, but the gusset felt pretty thin, which made us nervous about using it on heavier days. And while we'd like to see the brand extend its size range, this is an excellent option for anyone looking to keep it simple and comfortable, but still stylish. That said, period underwear likely doesn’t post any greater risk than other menstrual products when it comes to PFAS, but experts suggest washing before your first wear to reduce exposure.

One of the biggest brands in the period underwear segment is Thinx. Founded in 2013 by some friends with a few “gnarly period accidents” between them, Thinx is a game-changer in revolutionizing menstrual supplies. Looking and feeling like real underwear, Thinx’s line of period panties are washable, reusable, and incredibly absorbent. So many styles…so many sizes! The period underwear collection from Modibodi is definitely a fan favorite for a reason. First introduced in 2013, Modibodi’s line of period, incontinence, and leak-free underwear offers an excellent alternative to traditional tampons and pads, with styles available in different levels of absorbency. Much like the overnight options from Thinx, Modibodi, and Knix, this affordable style from Goat Union is incredibly absorbent and will keep you protected from unwanted leaks while you sleep. Adhering to the three R’s – reduce, replace, and reuse – these washable and reusable period panties are an ideal alternative to pads, tampons, and menstrual cups. We were a bit skeptical of the idea of an absorbent thong, but this product surprised us. It’s definitely not for heavy flow days, but as our tester noted, “If you're that rare person who likes to wear thongs while you have your period, and most importantly, you have a very light flow, I would absolutely recommend it.” It absorbed 1 teaspoon of fluid during our test without any leakage, which is exactly what it’s advertised to do. https://www.fda.gov/regulatory-information/search-fda-guidance-documents/menstrual-tampons-and-pads-information-premarket-notification-submissions-510ks-guidance-industry

How Does Period Underwear Work?

Editor's note: Thinx was part of a class-action settlement that alleged their products contain PFA chemicals. After speaking with experts, we still recommend Thinx products, but you can learn more about the settlement and PFAS in our "Your Questions, Answered" section below. Getting your period for the first time can be a super uncomfortable moment, both physically and mentally. If you're not used to toting period products, you can end up in, shall we say, less-than-ideal situations. But Knix has an approachable, beginner-friendly line of period underwear specifically designed for teens and tweens just getting used to their flow. Sized with growing bodies in mind, KT by Nix panties are available in lots of fun, bright colors, patterns, and styles like boxer briefs, bikinis, and boy shorts. You do get a little bit of that "wet" feeling when they're really "full". Personally I find it more comfortable then pads so I'm willing to put up with it

The biggest limitation to our testing was time, but we are already working on another round of testing. This time, we’ll analyze how these selections hold up over time and with frequent washing. Stay tuned! Susan S. Khalil, MD, director of the Division of Sexual Health in Obstetrics, Gynecology, and Reproductive Science at the Icahn School of Medicine at Mount Sinai Proof Leak Proof High Waisted Briefsheld 3 to 6 teaspoons of fluid in our testing, making them a great choice for moderate flow days. They’re also a stylish option with a durable lace waist and slimming high waistline.Style and Silhouette: Like regular undergarments, period underwear comes in numerous styles and silhouettes. Beyond traditional briefs and bikinis, there are hiphuggers, thongs, boy shorts, and high-waisted panties, like Proof Leakproof High-Rise Lace Brief Period Underwear. The shorts don’t come with the liner that the Aisle boxers do, so they are less absorbent, but I still found that they rarely leaked, and when they did, it was in the early evening after a full day of wear. While no evidence directly links period underwear to health issues, exposure to PFAS has been linked to thyroid disease and cancer. Another Healthline editor used these as her go to pair until lawsuit freaked her out enough to toss them (she is since willing to try Thinx again).

The materials that work best for you may also come down to personal preference and flow. “When made properly, all period underwear is effective and comfortable,” says Dr. Spencer. “Certain materials, such as nylon and cotton, in the outer layer may be more comfortable, however.”Our testers first evaluated the absorbency of each pair of underwear by pouring the maximum advertised amount of liquid onto the gusset. They noted how well the underwear absorbed the liquid, rating each pair on a scale of one to five. Materials: Safe and quality fabrics ensure breathability and effectiveness for your panties. Each product below contains nontoxic materials and uses fabrics to make customers as comfortable as possible.
