Our Flow Undies are the perfect companion to a zero-waste empowered period, bought once, to then last for years.

We chose regenerated eucylyptus Tencel for our Flow period undies because:

  • It is the most absorbent fibre available
  • It rapidly absorbs moisture and very quickly spreads it across its nanofibre structure, which means you will feel drier
  • It also holds 50% more fluid than cotton
  • Thermoregulating - it naturally has a thermal control to keep you cool
  • Incredibly soft and gentle against the skin
  • Naturally antibacterial without the use of toxic chemicals
  • Highly breathable
  • Made from a renewable fast growing source, eucylptus trees

These qualities mean that we can engineer period undies without bulk. We use layers of Tencel in key areas to maximise aborption and still feeling light. 

They inclued a waterproof, breathable layer made from Oeko-Tex certified toxin free PU laminated Tencel. It extends from the front gusset up to the back waist, ensuring no leaks when sitting and lying down. 

We have developed a matching reusable liner pad that sits on the gusset for additional absorption on heavy days, this extends the length of wear and makes it easy to change when at work withouth changing your undies. 

Our Flow undies as a sustainable solution, but also one that reconnects you to your body and away from commercial plastic mass market products. 

One pair of undies can be worn all day, if it is a heavy day add our Flow Washable Liner or make your own (we have shared the pattern on our liner listing). 

And most importantly, choosing these period undies means another person that cannot afford them is getting period undies for free one-for-one, let's erase period poverty. 


TENCEL™ is an eco-friendly fiber made from responsibly sourced wood pulp. The wood pulp is dissolved in a closed-loop process with a non-toxic organic solvent, then the solution is forced through tiny holes in order to create an absorbent biodegradable fiber that feels softer and lighter than cotton.

I own a few different period brands and the quality difference between them all is crazy. THESE ARE THE MOST BREATHABLE undies I have worn. I love my period undies but in the summer they can get a bit sweaty and uncomfortable, these have not. I am also pretty happy with the coverage, I haven’t worn them at night yet but I am pretty confident they are going to be awesome.

Love these undies. Very comfy material and sit well. I have a medium to heavy period and these manage it well. Dry quickly after washing too which is very handy
