On your light days, you may want a thinner and well, lighter, panty, while on heavier days, you may opt for something with a higher absorbency level. We encourage you to stock up on a variety of absorbency levels so that you’re prepared for any flow, any time. However, there are no rules saying you can or can’t wear a particular pair, regardless of flow. Whatever makes you the most comfortable, wear it. As you browse online look for the blood drop icons that serve as an indicator of absorbency level.
