Product Information

PRO: You can wear the best period pants all day without worrying about changing a tampon. You can also wear them to give you extra protection alongside a pad or menstrual cup on heavy flow days, or to protect against incontinence or for peace-of-mind postpartum. If you were on the fence about making the switch, let this be the review that tips you in favour of period pants. Sincerely, a shameless heavy flow girlie.”

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 Menstrual cups are an alternative to sanitary pads and tampons. The cup is made from silicone and you put it inside your vagina. Why we love them:"As someone who's woken up to that dreaded crimson stain on my white bed sheets more times than I care to admit, finding a solution to aunt Flo's monthly crimes was top of my shopping list. Enter Modibodi. We're three years into my switch from tampons and pads to period pants and, I can say with complete honesty that Modibodi period pants have transformed the quality of my sleep.Because of a class-action settlement by Thinx that alleged PFAS were found in their products, many people are worried about the impact of these chemicals in period underwear. We rated Thinx For All Women’s Super Absorbency Brief period underwear a perfect 5 for overall value and comfort. This period underwear also features amazing absorbency (five tampons or 2.5 pads worth). If you need period underwear with super absorbency, you won’t be disappointed. However, this underwear is so comfortable that it’s also a great choice for light and medium-flow days. You can calculate when your period will start and your peak ovulation times using an online period calendar.

When do periods start?For heavy flow days or overnight use, Goat Union Overnight Period Underwear topped our list. Goat Union claims their underwear can absorb 6 teaspoons of fluid, and this claim held up to our testing. “These absorbed slowly but did absorb,” noted our tester. “The gusset was wet, but the exterior was dry. There was no overspill.” Premature ovarian failure. Premature ovarian failure refers to the loss of typical ovarian function before age 40. People who have this condition, also known as primary ovarian insufficiency, might have irregular or occasional periods for years. This underwear isn’t as stretchy or soft as some of the other products we tried, and according to the manufacturer, it also runs on the small side. (Of course, if you’re used to purchasing products that are primarily cotton, those are both qualities you’d expect.) “It absorbed 3 teaspoons easily,” our tester said. “The outside was dry but cool to the touch.” The underwear also comes with a handy reusable pouch for machine washing. Just be sure to do a pre-rinse before the main wash.
