When it comes to period underwear, everything is designed to make your life easier! High-waisted, shorty, thong, G-string—today, discover a new style and cut of period underwear that’s a little different: the detachable period underwear!

Need menstrual protection that’s both practical and comfortable? Detachable period underwear is a real game changer: it lets you change your protection without taking off your trousers. No need to undress to change your period panties anymore! It’s incredibly handy when you’re not at home.

In this guide, we explore the different fastening systems, the absorbency levels suited to each flow, soft materials like organic cotton and the benefits of this washable, detachable protection for your active life. You’ll also discover Gigi, Louloucup’s detachable model, a detachable period panty made in Europe from organic cotton, ideal for getting through your menstrual cycle with complete peace of mind.

Detachable period panties: how does it work?

The concept is ingenious: hooks or other fastening systems let you open your menstrual underwear and remove it completely without having to undress. This practical, leak-proof solution is perfect for active women, travelers or anyone who works far from home, as well as for teens in middle school, high school and university who spend long days out and about. The absorbent layer sewn into the core of the underwear protects you effectively, so you can relax and feel confident. 🧘🏼‍♀️

Fasteners and quick-release systems

Detachable period panties use different fastening technologies, each with its own advantages. Depending on the styles and brands you choose, you’ll find a wide variety of systems: clips, butterfly clasps, hooks, buttons, etc.

The snap buttons (the same ones found on our favorite bodysuits😉) are ultra-fast and sturdy fasteners, perfect for discreet changes in the restroom.

Velcro offers precise adjustment but wears out over time.

A zipper is another option; it makes removal super quick, ideal when you’re in a hurry. You’ll just need to see how you feel about the extra thickness.

The butterfly clasp is discreet and comfortable, but it does take a bit of getting used to handling it.

Traditional hook-and-eye fastenings, like those on our bras, are a safe bet. We’re familiar with this discreet system.

The clip system (similar to some bikini fastenings) is secure but can be quite visible.

Or the invisible opening is a fairly discreet system with hidden snaps at the crotch.

Each system meets specific needs. Press-studs will appeal to adventurers, while Velcro will suit those looking for a made-to-measure fit.

The Gigi menstrual panty from Louloucup: its fastening system


The Gigi panty, for example, has side hooks positioned between the hip and the groin for super-quick changes, even with trousers on. Gigi’s real bonus? Its 3 rows of hooks that let you adjust the fit perfectly around your hips.

Type of fastening Speed Durability Discretion Use
Snap fasteners 5–10 sec very good discreet travel
Velcro
10–15 sec medium silent clarification
Zipper 3–5 sec good very discreet sport
Invisible slit 10 - 15 sec very good invisible night

An absorbent, comfortable, leak-proof protection for everyday wear

A good detachable period panty captures menstrual flow without feeling wet, adapts perfectly to your body shape and gives you optimal protection during your period.

Well-designed elastics hold the insert in place without digging in, while technical fabrics keep you dry for up to 12 hours.

The openable (or not) period panty is made up as follows:


  • an absorbent layer that quickly captures the flow for an instant dry feel,

  • a breathable membrane: waterproof yet allowing air to pass through to prevent odours,

  • natural materials: organic cotton, bamboo fibres against the skin for maximum comfort.

Tips for changing on the go

Spending a long day away from home with a fairly heavy flow, or suddenly getting your period a few days early? A detachable menstrual panty can really make your day easier and save you a lot of stress.

Using it couldn’t be simpler: unhook the clasps, pull it on, then close the clasps again, adjusting it to your body. It only takes a few seconds and you don’t need to take off your trousers or outfit.

It’s ideal between two meetings, two classes, or while traveling.

The detachable menstrual panty, the ally for irregular periods


You can use this type of period panties in many situations. They’re especially useful and much appreciated by anyone with slightly irregular periods, surprise bleeding, or even spotting. Detachable period panties are therefore an excellent backup menstrual protection! They slip easily into a handbag, sports bag, or school bag and can be put on in seconds to provide welcome absorbency.

Detachable period underwear: absorbency and materials

A detachable menstrual panty can offer different absorption levels depending on the model: from light to medium flow, or heavy to very heavy flow.

Knowing the different absorption levels and fabrics used in a washable menstrual panty helps you choose the safest and most eco‑friendly solution. You’ll enjoy absorbent, economical and environmentally friendly protection, without compromising your well‑being.

Which absorbency for which flow?

Manufacturers generally classify panty absorbency into three categories:

light flow (1 to 1.5 tampons, 5–10 ml),

medium flow (2.5 to 3 tampons, 15–20 ml),

and heavy flow (4 to 5 tampons, 25–30 ml).

Flow type Tampon equivalence Volume (ml) Wear time Recommended timing
Light 1 – 1.5 tampons 5 - 10 ml 8 to 10 hours light flow, beginning/end of cycle, vaginal discharge, spotting
Medium 2.5–3 tampons 15–20 ml 6 to 8 hrs
In-between days
Heavy 4 tampons 25–30 ml 6 h to 8 h …peak flow and nighttime
Very heavy 4 - 5 tampons 35–45 ml 4 to 6 hours hemorrhagic flow, nighttime, long outings

Gigi and its absorbency level


The detachable Gigi menstrual panty is suitable for light to medium flows. It’s ideal for anyone whose periods are naturally light or normal. It also works very well for those with heavier periods at the end of their cycle, when the flow is lighter.


Gigi is also perfect outside of your period—during ovulation if you experience heavy vaginal discharge, or in case of spotting (light bleeding between periods).

Safe, certified composition of the openable period underwear

We’ll never stop saying it: when you buy period panties, it’s important to check their composition carefully. Choosing washable menstrual products instead of standard pads and tampons is great, but opting for low-end products made from plastic-based fabrics isn’t much better.

Prioritize local or European manufacturing and safe, patented, certified fabrics. The best choice for you is obviously natural materials from organic farming, such as organic cotton or organic bamboo—no risk of plastic nanoparticles or pesticides!

To help you choose, we recommend paying special attention to the inner lining of the period panty.

Gigi with its GOTS-certified organic cotton lining


The lining in contact with Gigi’s intimate area is made from GOTS-certified organic cotton. This fabric layer offers softness and breathability, reducing the risk of irritation.


The entire panty is OEKO-TEX 100 certified, guaranteeing it is free from harmful substances.
