Why we love fluxies
Leak proof period pants that are made carefully, consciously and designed to empower both the people that wear them and the people that make them? You really can have it all with fluxies. All fluxies undies are made of TENCEL™ modal fibres – a biodegradable material sourced from renewable beech tree crops – and ethically manufactured only in trusted, certified factories. What's more, with every purchase, fluxies either gives back a percentage of their sales or donates reusable period pads and period pants to combat period poverty worldwide.
Description

FLUX Undies' best-selling Classic Bikini Heavy Flow Period Pants combine style with function. Holding up to four tampons' worth, they are a dream to wear day and night and can be worn leak-free for up to 12 hours to help with heavy periods and provide support for light incontinence.  Feel comfortable and confident that you're protected from any leak life might throw at you, even on your heaviest days. 

Features 

  • For Periods, Leaks and Incontinence
  • Holds Four Tampons' Worth / 20-25ml
  • Wear For Up To 12 Hours Leak-Free
  • Soft, Stretchy and Comfortable
  • Lightweight and Quick-drying
  • OEKO-Tex Certified Materials
  • Free From Toxins, Chemicals and PFAS/PFOA
Wash and Care

Rinse with cold water, then just throw in with the rest of your laundry up to 40°C!  Your usual detergent will be fine, but don't use fabric softener as this will affect absorbency. Don't tumble dry, but you can always pop them on your radiator for a quicker dry.

95% Tencel Modal, 5% Elastane, 95% Tencel Modal, 5% Elastane, 100% Microfibre, Biodegradable TPU

Wish I’d bought these years ago

Comfortable, pretty, so much more eco friendly!

Super light yet very absorbing

I feel like this model is lighter than the high waisted transparent one, which is a nice feel on the body. Tranquility of mind wearing this, perfect for 8hours in heavy days in my case.

Comfortable

Comfortable fit, great sizing, love the lace design, look very similar to regular pants. Perfect as a backup for a cup.

So Comfortable

I wish these had been in my life for forever! Truely life changing. Much more comfortable than pads and tampons and reducing landfill. Win win! I found them true to size.

Good but could be better

The seam on the butt was disturbing me the whole time. You should make the padding go all the way up to the back. Also I’d make it a bit longer on the front as well - good for those of us who sleeps on the stomach.
