Product Description

FLUX sustainable period underwear is available in a hi-waist style for those who enjoy full coverage, and when you need the most protection and support. Made from soft modal, the hi-waist period pants are super comfortable and suitable for both day and night. Wear for up to 12 hours without any leaks – whatever your flow. Designed to hold up to 4 tampons worth of liquid. Suitable for vegans and free from any synthetic fragrances, parabens and other nasty chemicals.

The period pants are made with a moisture-wicking soft top layer to keep you fresh and dry, a second anti-microbial layer to keep you clean, and a leak proof breathable PUL barrier – perfect for periods, leaks and incontinence.

FLUX undies use Oeko-Tex certified fabrics and the pants are ethically made in China, in a family run factory that is ISO and BSCI approved, where employees are given proper pay and adequate rest breaks.

With FLUX’s ‘By You, For Her’ scheme, a girl in need will receive a reusable menstrual cloth pad for each pair of FLUX undies bought.

These are amazing and I wish I'd known about them before. No matter how heavy my period is I no longer have the worry at work that I might have an embarrassing incident.rnThey take a little while to dry, but I guess this has to be to allow them to be so absorbable.rnI've ordered another couple of pairs. rnWould recommend to anyone.
