The magic behind the underpants✨
Everyone periods differently. Generally speaking, a good place to start is at least 3-5 pairs so you're coverd for the duration of your period without doing extra laundry. Consider the heaviness of your flow and how many pairs you'll need on each day and night to be safe.
Overnight: Absorbs 6+ tsp of blood, that's about 6 pads worth of blood. Perfect for overnight protection or on heavy days.
Heavy: Absorbs 4-6 tsp of blood, or 4-6 pads. Perfect for overnight protection or on your heaviest day when changing into a fresh pair might not be convenient.
Moderate: Absorbs 3-5 tsp worth of blood, the equivilant of 3-5 pads or tampons.
Light: Absorbs 2-3 tsp worth of blood, the equivelant of up to 2-3 pads or tampons.
Zero: Wicks away moisture, sweat and discharge and features a leakproof layer so nothing shows through.
You know how you just know when to change a pad or a tampon? Period underwear are no different. If it's your first time wearing them, check every so often, if they start to feel bulky or like they're not absorbing anymore then they have likely reached thier limit.
Yeah! Depending on the heaviness of your flow on that day, and the absorbency level of the period underwear you want to wear. As an example, we use 3-4 pairs of moderate and heavy styles per day, on day 1 and 2, but only 1 pair of lighter underwear all day on days 3 to 6. If it's your first time using period underwear, try them at home first to get to know your flow threshold (how long you can wear one pair for before needing to change).
The short answer? Nope! Depending on the absorbency level of your period underwear and the heaviness of your flow, you can wear them on their own or as back up to tampons or a period cup. Our overnight and heavy period underwear are designed to be worn on heavier days on their own, and our light to moderate styles can be worn on their own on lighter days and as back up on heavier days.
We've made it easier to get more savings, bigger discounts and better rewards for making the switch to reusable period undies. We also know that starting with at least 3-5 pairs is a good place to start, and you can build your period underwear plan from there.
