The dry heat pack made of flaxseed from Sisters Republic (100% organic cotton) is ideal for relieving your premenstrual pain (PMS). You can simply place it on your abdomen or back, ideally by putting it in our specially designed belt so you can continue to move freely. Our heat pack can also be used on the cervical spine area or simply to warm your bed. It is also suitable for children.
PLEASE NOTE: During the first uses, a slight moisture may be released from the flaxseeds, this is completely natural and does not affect the properties of the hot water bottle in any way, no worries!
How to use the flaxseed hot water bottle from Sisters Republic?
The hot water bottle must be hot in order to maintain the temperature for as long as possible, without causing burns upon skin contact. 🔥
TIP: If you want to use the hot water bottle without being restricted in your movements, use the specially designed hot water bottle belt from Sisters Republic!
I recommend it 100 %.
"This is the first time I have bought period underwear and I am completely satisfied! During heavy menstrual flow, I used the ones with absorbency Super and there was no leaking (even at night!) I recommend it 100%!"
Marine T.
Thank you, Sisters Republic!
"It is a real innovation for all women. You experience your period differently with it; I no longer feel uncomfortable like I did with tampons or cups. The period underwear in the pack have different absorbency levels, so you have the right protection for each day."
Camille S.
"You are really thin and pleasant."
"I have a light flow because I'm on the pill, so I've taken a panty with absorbency Medium for the heaviest day just to be safe, and for the rest of the time, two in 'Light'. I feel like I can't even feel my period anymore because the underwear is so thin and ultra-comfortable. I can wear it all day without worrying, ..."
Annabelle M.
Pleasantly surprised
"For someone who only uses tampons, it felt a bit strange at first... I was afraid that something would leak, but that doesn't happen. The panty absorbs all the fluid very quickly. I'm so glad I don't have to use a tampon anymore, especially at the end of my period when it's really not comfortable!"
Celine R.
It's great
"What is really great is the material, I feel completely comfortable. I chose the strength 'Super', even though I have a rather average blood flow, but I wanted to make sure that nothing leaks out."

"Underwear is no longer to be imagined without."
"Essential is the adjective that comes to mind when I think of period underwear. The underwear is very comfortable, the blood absorption is good, and above all, at night you can have your peace. Thank you very much for these efficient and comfortable panties that almost make you forget that you have your period!"

I recommend it without hesitation.
"It is truly an innovation for all women. I experience my period very differently today..."

Depending on the length of your cycle, whether short or long, you will need 4 to 10 pairs of underwear. If you want to wear your menstrual underwear day and night and wash them all at the end of your cycle, you should count on having between 8 and 10 pairs. If you want to wash them to reuse several times during your cycle, 4 to 5 pairs will be sufficient. You should count on at least one pair for the day and one for the night, all multiplied by the number of days your period lasts.
