Period underwear can feel unfamiliar at first because it changes how period protection works. Instead of having to layer pads or insert products, the protection is built directly into an underwear-like structure. This is why understanding the basics matters. Knowing how a period panty absorbs flow, how period panties compare to disposable pads, and what makes them safe for your body helps you understand how this is the right choice for your cycle, especially if you are looking at period panties for heavy flow.
Once the mechanics are clear, the rest of the decision becomes far less complicated.
What Makes Period Panties Truly Ultra-Absorbent
Ultra-absorbency is not about making period underwear thicker or heavier. It is about designing the absorbent gusset to manage flow efficiently while remaining comfortable against the body. When done well, period underwear can make you forget you’re even on your period.
At the core of Mahina’s period panty is a carefully engineered three-layer gusset, designed for long wear and real flow patterns. It includes:
- Top layer: Wicks away moisture to keep your skin dry
- Middle layer: Absorbs and holds blood in the core
- Bottom layer: A protective leak-proof barrier made from breathable TPU
Instead of bulky stitching, Mahina uses bonded seams to seal the gusset. This reduces leak points and creates a smoother, flatter fit against the body. Plus, to avoid the hassle of layering extra products for just enough coverage, Mahina’s period panties provide front-to-back coverage that keeps you secure and leak-free during movement, long hours sitting in one place, and sleeping in different positions. With a 12-hour wear time, Mahina’s period panties come in 3 various absorbency levels to adapt to your needs. Absorbency works best when it supports the body quietly, not when it demands constant attention.
How Can You Find The Right Absorbency For Your Flow?
Your flow does not stay the same throughout your cycle. Some days are lighter, others are heavier, and your protection needs to shift with it. To make this easier, Mahina created the Know Your Flow (KYF) quiz. It takes about two minutes and helps you identify the absorbency level that suits your body and routine.
-
Medium (25 ml)
Designed for moderate flow days, this level holds roughly the equivalent of 3 pads, 4 tampons, or 1 menstrual cup over 12 hours. You can identify it by the 2 stitch lines on the side. -
Heavy (40 ml)
Suited for heavier flow days, this option absorbs around 4 pads, 5 tampons, or 2 menstrual cups in 12 hours. It is marked with 3 stitch lines. -
Super Heavy (50 ml)
Ideal for very heavy flow or overnight wear, this level holds up to 5 pads, 7 tampons, or about 2.5 menstrual cups over 12 hours. It is easy to recognise by 4 stitch lines.
Instead of constantly checking the time, worrying about leaks, or planning your day around the next pad change, you can choose period care that matches your flow. When period care is reliable, comfortable, and provides the protection you need, you can move about your day freely and without stress.
How Period Panties Compare To Disposable Period Products
Disposable pads have been widely used for years, but their limitations often show up on heavier flow days. Shifting, bunching, and moisture build-up can lead to discomfort and frequent readjustment.
-
Comfort and fit
Mahina’s period panties feel like regular underwear, which helps your period protection stay in place, move with your body, and reduce irritation caused by plastic-heavy period products that can trap moisture and also cause rashes. -
Reliability over time
Every single one of Mahina’s period panties can be washed and reused 100 times. In 12 hours, Mahina’s period panties in the highest absorbency level can replace 5 disposable pads, reducing the need for constant changes. -
Lower waste, less effort
Reusable period panties significantly reduce disposable waste and remove the cycle of repeated purchases. This can help you save money over time and reduce the stress of remembering to restock pads every month.
Together, these differences make period panties a more consistent and dependable option for managing periods, especially during heavier flow days.
What Makes A Period Product Safe To Wear
Because a period panty is worn for hours against sensitive skin, safety matters just as much as absorbency. A body-safe period product needs to be designed with both materials and long-term wear in mind.
When assessing whether period panties are safe, a few essentials stand out:
- Fragrance-free and dye-free materials that minimise irritation
- Breathable fabrics such as cotton or modal that allow airflow
- Skin compatibility and toxicology testing for all skin-touching components
- Compliance with recognised international safety standards
- Transparency around testing methods and certifications
Mahina’s period panties meet these standards through testing conducted by NABL-accredited laboratories. Every component, from fabric to thread, is tested to ensure it contains no toxic chemicals, banned amines, or restricted substances.
Mahina tests period panties after real-world use, ensuring that safety testing also extends beyond new products. Even after months of wear and repeated washing, microbial levels remain well below accepted limits, indicating minimal bacterial, yeast, or mould growth. This ensures the underwear remains hygienic and safe over time, not just on the first wear.
A New Kind Of Ease During Your Period
When period care is designed with care and intention, it starts to change how your days feel. Mahina’s period panty focuses on comfort, reliable wear time, and body safety in ways many traditional products have not. Instead of planning your day around pad changes, dealing with irritation, or facing the uncertainty of leaks and stains, you can move through your day and night with fewer interruptions.
With absorbency that holds steady, materials that are gentle on skin, and safety checks that extend beyond first use, Mahina’s period underwear works with your body rather than against it. Over time, this kind of reliability softens the mental load of managing a period and makes space for a calmer, more settled experience each cycle.
