The Best Period Underwear for Heavy-Flow Days

With moisture-wicking and front and back absorbent features, 4period’s panties will keep you safe and dry through the day during your shark week. This hipster-style pair of underwear gives you full back coverage and the elastic band doesn’t ride up, guaranteeing maximum comfort.

These panties are also made from non-synthetic fabric, which is bamboo-derived and silky smooth to the touch. They’re ideal for sensitive skin and the fabric is light enough to move with you. We chose this as the best product on the list because, besides mensurating women, ladies undergoing postpartum and urinary incontinence can also use it — it offers leak protection for all!

These hipster panties can absorb flow during mensuration or c-section and postpartum recovery. They are made of 5% spandex and 95% natural cotton, with a 100% premium cotton lining that is perfect for spotting and light flow. Innersy’s panties also use PUL fabric and an extended crotch lining to prevent leakage and messy stains.

The front lining is higher than other panties and goes up to the waistband in the back, offering more protection and preventing your clothes from getting dirty. Meanwhile, the thick liner keeps you dry and clean throughout the day and even after waking up from a night of heavy flow. On heavy flow days, you can pair these panties with a tampon, menstrual cup, or pad for maximum protection.

Bambody Period Panties make period protection affordable and simple. You’ll find these panties in various styles ranging from sporty hipsters and straight-up briefs to lace-trimmed bikinis. They can absorb blood equivalent to two tampons, protecting you from stains during heavy flow days. 

This pair of underwear is made from bamboo, which feels soft against the sensitive parts of your body. The fabric is breathable and cool, so you’ll feel as comfortable as in your daily underwear. Plus, these are eco-friendly, so you’ll be satisfied knowing you’re protecting the environment while saving money.

This brief-style period underwear offers relief from stains during your red week. You can use them with pads and tampons to prevent spills and leakage. These panties are especially suitable for women who experience postpartum bleeding, as they are leakproof, comfy, and easy to clean.

These briefs are made of 17.8% cotton, 84% nylon, and 16% spandex, offering support and comfort without irritating the skin. They also offer full coverage from front to the back, so whether you’re actively working or simply sleeping, you don’t have to worry about getting embarrassing stains on your clothes.

Made of 5% spandex and 95% modal, these period panties give you two tampons worth of absorption lock. Plus, they provide extra protection when you add the additional backup of tampons, pads, or menstrual cups during heavy or regular flow days. And, in case you’re concerned about aesthetics, they have a high-cut bikini style that offers a sleek fitting without panty liners.

Even better, you can also use the Neione period panties during menstruation and postpartum. This is because the leakproof structure of the underwear locks in unexpected spillage and improves absorption. So, whether it’s that time of the month or you’re recovering from a recent pregnancy, this period underwear is ideal.
