Frequently asked questions
Everything you want to know before you choose
Who is Seamless for?
Seamless has a seamless fit and absorbency level 4 of 6. The model suits a moderate to heavy flow. The smooth fit is easy to combine with close-fitting clothes.
Can I wear them without a pad or tampon?
Yes, if the absorbency matches your flow between changes. Check more often the first few times, and use extra protection if you like while you get to know your routine.
When should I change into a clean pair?
Change when you feel damp or the fluid is no longer absorbed as before. Wear time depends on your flow and can vary from day to day.
What materials are in the model?
100% cotton in the layer against the skin. Integrated absorbent layers and a waterproof barrier. Smooth outer fabric with a seamless fit.
How do I choose a size?
Measure your hips and waist and compare with the size guide. Prioritise the hip measurement. The underwear should fit snugly without being tight; choose according to your measurements and preferred fit.
What do I do if I need to change when I'm out?
Bring a clean pair and a waterproof bag. Keep the used pair in the bag until you can rinse and wash it at home.
How do I wash the underwear?
Rinse in cold water after use. Wash at 40°C without fabric softener or bleach, and always follow the care label in the product. Let air-dry completely. Avoid tumble drying and ironing.
How many pairs do I need?
You may want to start with one pair to try the fit. For regular use, you need enough clean pairs for your changes, including while other pairs are being washed and dried. Use the calculator as an estimate based on your own routine.
