do you have questions about ooia products?

On this page you will learn everything on how to find your correct size and how to use ooia products.

what is your ooia underwear size?

ooia products are true to size. You can simply order your usual size.

If you are unsure which size fits you, simply take your hip measurement and compare it with our size chart.

You measure the hip circumference best horizontally at the widest part of the buttom. The tape measure should be flexible, fit snugly, but not cut in.

If you are between two sizes, order the smaller size. Exception: if your thighs are very strong and you are between two sizes, we recommend ordering one size larger.

what is your ooia nursing bra size?

The best way to measure the chest circumference is horizontally at the strongest part of the chest. The tape measure should be flexible and fit snugly, but not cut in. Then measure the underbust circumference under the breast. The tape measure should be tight here. Your size results from the measurements of the chest circumference and the underbust circumference.

The ooia nursing bra is suitable for any bust up to cup size C. If you have cup size D and larger, we advise you to choose our nursing bra for big cups. If you are between two sizes, we recommend that you order the bra one size larger.

how do you create your ooia period set?

Your period is unique. Therefore, your ideal set of ooias is also unique.

How many ooias you need depends on many factors: the strength of your bleeding, the duration of your period, whether you want to use ooia alone or in combination with other period products, and how often you want to wash them.

To cover your entire period, most women* will need five to six ooias.

The logic behind this is: one ooia for the day and one for the night - wash them after two days, and while the first four ooia pants dry, put on the two you haven't used yet. Then it's back to the first one.

Basically, one ooia has 1-6 tampons/10-30ml intake, depending on the model.

If you bleed more in a day, you can either use more than two per day, or wear ooia along with a tampon or menstrual cup.

Some will get along with fewer ooias if, for example, you live in a household that washes daily.
