Frequently asked questions
Everything you want to know before you choose
How do I choose the right size?
Flexi comes in two variants: 2XS–M and L–3XL. The stretchy material means each variant covers four sizes. Check the size chart and compare your measurements before choosing.
What flow are they suited for?
Flexi has a stated capacity of 45 ml and suits a moderate or heavy flow, with changes adapted to your needs. How often you need to change depends on your flow; the capacity in millilitres doesn't equal a fixed number of hours.
Can I wear them without a pad or tampon?
Yes, when the model's absorbency matches your flow. The absorbent protection is built into the underwear. The first few times, check more often how they work, and change pairs when you feel damp.
Can I sleep in them?
Yes, depending on how heavy your flow is. Flexi has an absorbent area that extends partly towards the back. Put on a clean pair before going to bed, and adapt the wearing time to your needs.
How long can I wear one pair?
Up to 12 hours, depending on your flow. This is a maximum, not a guaranteed wearing time: change sooner if you feel damp or if the absorbent area is saturated.
How many pairs should I use?
It depends on how often you change, how often you wash and how long they take to dry. You need enough pairs to always have a clean, completely dry pair ready. You can start with a few and adjust the number after the first few times.
