Menstrual bikini bottom - Spruce
IMPORTANT: Menstrual swimwear on sale is NOT EXCHANGEABLE AND NOT REFUNDABLE. This is a final sale.
Le maillot de bain menstruel Marie fil looks like a regular swimsuit. It therefore allows swimming during menstruation and ensures effective menstrual protection. The menstrual swim bottoms are discreet and leak-free.
Menstrual and eco-friendly swimwear bottoms
The bottom of my menstrual swimsuit is made in an eco-responsible way, but that doesn't make it any less reliable! Women can still trust it with their eyes closed, thanks to:
-
An absorbent lining permanently integrated at the gusset level
- hyper discreet
- absorbent quickly menstrual blood doesn't inflate in water
- hiding a thin waterproof layer for watertight protection without risk of leaking in water or through the swimsuit
Menstrual swimsuit suitable for all flows
The menstrual swimsuit can be used with a light flow. Have a heavier flow? Know that it works wonderfully with a menstrual cup.
Swimming despite the rules
Women often like to enjoy the water or the sun for a long time. That's why the swimsuit has snap buttons* located on the inside to add absorbent inserts during the day. This insert will act like a washable sanitary pad to protect against water from the outside:
-
A insert
- included with the jersey, both inside a super handy waterproof pouch for transport
- composed of the same absorbent fabric that used for the lining at the gusset level
- interchangeable as many times as you want throughout your menstrual flow.
Discrete snap fasteners
- ultra-thin (so you never feel or see them through your swimsuit)
- in plastic (to avoid rusting due to humidity)
Environmentally responsible company concerned about the environment
Wear the menstrual swimsuit Marie fil means choosing to be comfortable and feel good in our skin, in the water or not, menstruating or not. It’s also about making a positive difference both in your life and for the environment. 💚
