Flow: Super Heavy

Great product

I have been using Flux for three periods now and have gradually reduced the amount of tampons and pads that I am buying. It takes a while to get used to the flow / gush feeling without the normal wave of panic about leaking everywhere. I would say build up your trust slowly and if you feel you need extra protection of a tampon than go with it. But these pants do a great job.

Flow: Light

Just ok...

I was excited to use my new Flux panties this weekend and found some pros and cons...
Pro- fits true to size, comfy high waist.
Con- the pad isnt long enough in the front and leakage overflows through the panties. Also wish the material was more breathable and eco friendly.

Flow: Moderate
Products used: FLUX Undies, obvs!
Far better than I thought

Very comfortable, no leaks, no smell and better for the environment. What more could you want!

I'm really pleased with these!! I've used the moon cup for about 3 or 4 years now, and have found on the first few days of my period where I usually have more pain I just don't want to wear the moon cup, and these pants are a great alternative for those days! Really comfy, a bit on the small side for me, I'm a size 8 in everything usually, including underwear, so that's what I ordered, but wish I'd have ordered a size bigger now, but they're still comfortable and work well so I am still happy! I wore them on the heaviest days of my period and no issues! Thank you so much for creating these!
