12 hours leaking
proof guarantee

Your leakproof questions,

answered.

The first layer, made of absorbent cotton, allows the blood to pass through to the lower layer, keeping you completely cool and dry without any sensation of moisture. The second layer, made of bamboo fiber, is super absorbent and can hold the equivalent of 5 tampons. Finally, the third layer is waterproof and prevents leaks. Everything is tailor-made to keep you dry all day or all night.

Happy Flow is crafted from materials certified to meet OEKO-TEX and CoolmaxFreshFX standards, ensuring their health safety. After consulting with gynecologists, it is recommended to wear them for 8-12 hours, depending on the intensity of your period. Additionally, the layer features an antibacterial treatment, ensuring a high level of safety and hygiene.

Happy Flow can withstand wash temperatures of up to 60 degrees without compromising absorbency. However, this may reduce their lifespan and cause color fading, although black and beige variants remain resilient. For optimal durability, it is advised to wash them at 30 degrees.

1-2 times a day. You can wear one pair of the underwear for 8-12 hours. But it depends on the strength of your period.

The absorbent layer of Happy Flow underwear contains an antibacterial treatment, which guarantees a high degree of hygiene and at the same time eliminates the formation of unwanted odors.

The underwear is suitable for anyone, catering to all menstrual individuals of all ages. It accommodates both light and heavy flows, as well as weak urine leaks and other discharges.

Very nice material, comfortable. They never betrayed me. The size and cut are perfect for the size I normally wear. I use them at home on lazy days and weekends, at night. I have also recommended them to my friends.

I like the product very much, I am using happy flow every month and even I would wear them all month long, because they are comfortable. Especially I like to wear them during training and running, when I can't not affort any 'accident'. I recommended also to all my friends and everyone is satisfied and happy.

Purchase for my 11 year old daughter and me

Purchase for my 11 year old daughter and me: a real joy! No leaks, no odor and no feeling of humidity. The only problem is not knowing if you still have your period because of the black panties.
