10 Best Period Panties 2025 in the United States

The Bambody Absorbent Panties are designed to be a comfortable and reliable option for period, post-partum, and light bladder leakage protection. Made primarily from soft, breathable rayon derived from bamboo, with some spandex for stretch, they feel silky and close to regular underwear. Their 4-layer design can absorb the equivalent of about four tampons, which makes them good for medium flow days or as a backup with other period products.

The full coverage and elastic fit help prevent leaks whether you’re active during the day or sleeping overnight. These panties are reusable and easy to care for—just machine wash and air dry to keep them in good shape while being eco-friendly. They’re suitable for both teens and adults, especially those looking to reduce disposable product waste and avoid bulky alternatives.

While they absorb well, they might not suit heavy flow days or those needing maximum protection, and air drying means a bit more patience compared to quick-dry fabrics. They provide a practical, comfortable, and sustainable choice for everyday period or light leakage needs.

The TIICHOO Period Underwear offers strong absorbency with built-in four-layer protection, holding up to 50 ml, which is about the same as four tampons. This makes it a solid choice for heavy flow days, overnight use, or even light bladder leaks. The material feels soft and smooth, thanks to a high rayon content, so it’s comfortable to wear throughout the day. Its design provides full coverage from front to back, which helps prevent leaks whether you're sitting, lying down, or moving around. This kind of coverage is reassuring and reduces worries about stains on your clothes or bedding. The underwear is reusable and free from harmful PFAs chemicals, making it safer for your skin and better for the environment compared to disposable options. Washing them is straightforward — soak first, then machine wash in cold water — which helps keep the absorbency effective over time.

On the downside, the product comes in a medium size pack with five colors, which might be limiting if you want more variety or need different sizes. Also, while the material is soft, it includes elastane, so if you have very sensitive skin or allergies, you might want to check that first. These panties provide a convenient, eco-friendly option for women and teens looking for reliable leak protection during menstruation or light incontinence, combining comfort with practicality.

Thinx Teens Period Underwear is designed specifically for teenage girls, offering a comfortable brief style made mostly of soft cotton with some stretch for a good fit. It is quite absorbent, able to hold the equivalent of about 12 regular tampons or 3 pads, which means it can handle medium to heavy flow for up to 12 hours. This makes it useful both as a standalone option or as backup protection along with tampons or menstrual cups.

The underwear features a LeakSafe barrier to help prevent leaks and a moisture-wicking layer to keep you feeling fresh and dry, which also helps control odor. These panties require hand washing, which means they need a bit more care compared to regular underwear. While the material is mostly cotton, the addition of elastane provides stretch but might not suit those with very sensitive skin.

The product is FSA/HSA eligible and free from harmful chemicals like PFAS, supporting health and sustainability. These panties offer a reusable, eco-friendly, and reliable option for teens seeking comfortable and discreet period protection.
