Periods are an essential part of life for half the population, yet the products we use to manage them have often lagged behind our need for both comfort and confidence. Period underwear has quickly risen in popularity because it combines practicality, style, and sustainability. These undergarments are designed with absorbent layers that can hold menstrual flow without the need for a disposable pad or tampon.

In recent years, more women and menstruators have looked for alternatives to disposable products. The rise of sustainable living, concerns about waste, and the desire for greater comfort during periods have fueled this shift. Studies on young people in Australia, for example, highlight that the main reasons for choosing period underwear include comfort, leak protection, and environmental sustainability.

The appeal lies in its ability to feel just like regular underwear while offering hidden protection. Unlike bulky pads or invasive tampons, period underwear promises a more natural and body-friendly experience.

When evaluating which underwear qualifies as the “best,” several features stand out:

Period underwear is soft, discreet, and often more comfortable than pads that shift or tampons that cause dryness. Many people report they feel like regular underwear, which reduces the mental stress of “being on your period.”

Although the initial purchase is more expensive, good quality pairs last months to years, reducing the need to buy pads or tampons every cycle.

Disposable pads and tampons contribute significantly to landfill waste and plastic pollution. Period underwear offers a reusable solution that aligns with eco-friendly choices.

Unlike bulky menstrual pads, many brands design underwear that looks sleek and stylish. This adds confidence during a time when people often feel self-conscious.

Period underwear can be used alone on lighter days or as backup with tampons or menstrual cups during heavy flow. It also works well for overnight use or while traveling.

A single pair of high-quality period underwear may cost more than a full pack of disposable pads. This can be a barrier, especially for students or those on tight budgets.

While many pairs handle moderate flow well, they may not be reliable for very heavy bleeding unless changed frequently or combined with another product. Overnight leaks remain a possibility with some brands.

If not washed properly, menstrual blood trapped in layers can cause odor, bacterial growth, or skin irritation. Dermatologists warn that prolonged dampness against the skin can increase the risk of fungal infections.

Investigations into certain brands have revealed traces of PFAS (so-called “forever chemicals”) and antimicrobial coatings like silver, which raise concerns about long-term exposure. These substances may be added for waterproofing or odor control, but are not always desirable for sensitive skin.

Period underwear requires rinsing, machine washing, and air-drying. This may be inconvenient for those without easy laundry access. Harsh detergents or frequent tumble-drying can damage the absorbent layers, reducing lifespan.

Not everybody's shape or size finds a perfect fit. Ill-fitting underwear can lead to discomfort, leaks, or visible panty lines under clothing.

Health experts also point out that while period underwear is safe for most users, users should monitor skin health, change pairs according to flow, and ensure proper cleaning to avoid irritation or infection.

Period underwear combines the practicality of leak protection with the confidence of style. It is not without drawbacks, especially for heavy flow users or those with limited laundry facilities. However, when chosen carefully, it can be an empowering, eco-friendly, and comfortable option.

The best pair is the one that balances absorbency, skin safety, durability, and personal comfort while making the wearer feel good about themselves. With growing medical research, better designs, and greater consumer demand, period underwear is likely to remain a valuable innovation in menstrual care.
