Why is my period panty leaking, and what can I do?

Menstrual panties have established themselves in recent years as a fantastic alternative to disposable sanitary products (tampons and sanitary pads)! This new intimate protection, durable and reusable, has serious advantages.

While period panties are extremely reliable sanitary protection, they can sometimes leak.

Why does my period underwear leak? What can I do to fix it? Is period underwear really right for me? How can I avoid leaks? And are leaks actually preventable?

This is the most common cause. The period underwear you’re wearing isn’t suitable or sized to optimally capture and hold your menstrual flow. As a result, the absorbent layer of the panties becomes saturated. It can no longer store the flow properly and it overflows. Leaks are then inevitable.

To choose the right style of underwear for your flow, we can only encourage you to read our article: Which period underwear should you choose for your flow?

Before buying period underwear, you need to understand your menstrual flow. You can do this by observing and measuring it. You might need medium-flow panties for the first and last days of bleeding, but heavy or very heavy flow panties for the two “peak” days. Every woman is different, every menstrual cycle is different. Only you can truly know what suits you best!

You also need to follow the care instructions and adopt the right habits: rinse in cold water, machine‑wash at a maximum of 30°C on a short cycle, use a gentle detergent, no fabric softener, no tumble‑dryer, and air‑dry away from direct heat.

Depending on the activity, you need to choose the right pair of panties. For a peaceful night and restful sleep, we recommend a wide, highly absorbent style that can hold your flow while lying down (with a long absorbent pad extending both front and back). Same thing for your workout.
Avoid the menstrual thong or the pretty lace period underwear, and instead go for period panties designed for sport: seamless, invisible, for very heavy flow and that won’t move when you do.

Period briefs are highly absorbent underwear. They are designed to collect menstrual flow in the best possible way. A very absorbent gusset (with a high absorption capacity) is sewn into the panties and extends from the front to the back. This layer captures the blood, draws it in and holds it without swelling or becoming saturated.

This period product is durable, reusable and washable. In 2024, its huge advantage is that it’s eco-friendly and produces zero waste. No more non-recyclable plastic wrappers filling up your trash every month! Period underwear is green!

The menstrual panties are healthy for your health. Their composition is clear and transparent. We use clean, certified, and tested fabrics. No toxic agents, no pollutants or endocrine disruptors, no pesticides or petrochemical residues.

It’s practical thanks to its detachable system.

Period panties can be worn by teens, women in perimenopause, and new moms in the middle of their postpartum recovery!

To wrap up, remember that absorbent period panties come in many different underwear styles, shapes, sizes and cuts to appeal to as many people as possible and adapt to all body types: menstrual boxer, menstrual thong, menstrual shorty, high-waisted menstrual panty, plus-size menstrual panty, etc.
