Product Knowledge
  • Why buy a multipack?

    The average period last anywhere between 3-8 days, so let's be real, we want more than 3 pairs to manage our period. And if your like us, you'll want the best quality, comfort and protection possible for whatever life throws at you. We've made it even easier to get more savings, bigger discounts and better rewards for getting started with the comfiest period underwear in styles you'll love.

  • What do the different absorbency levels mean?

    Overnight: Absorbs 6+ tsp of blood, that's about 6 regular tampons and pads. Perfect for overnight protection or on heavy days.

    Heavy: Absorbs 4-6 tsp of blood, or 20-30mm of blood. 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 tampons or pads.

    Light: Absorbs 2-3 tsp worth of blood, the equivelant of up to 3 tampons or pads.

    Zero: Wicks away moisture, sweat and discharge and features a leakproof layer so nothing shows through.


    All our absorbent period underwear are made with leakproof period technology built right in.

    Layer 1: Wicks moisture away from the skin to keep you feeling dry.

    Layer 2: Our most absorbent pair can hold up to 8 tampons worth of blood, locking it in place.

    Layer 3: Front to rear leakproof fabrics ensure nothing feels wet or leaks through to the other side.

    You can be sitting, standing, running or jumping with confidence you'll stay dry and comfy. That's the magic of period underwear!

    Layer 4: Breathable black outer layer that keeps it all discreet.

  • Do I need to wear a pad or tampon with period underwear?

    The short answer: nope! Depending on the absorbency level of your period underwear and the heaviness of your flow, you can wear Scarlet period undies on their own, or as back up to tampons or our menstrual cup.

  • How do I wash them?

    Washing them is easy! Just throw them in with the rest of your laundry on a cold wash cycle (your other clothes will be fine!), or give them a quick rinse first if you're worried. You can tumble dry on low, or hang dry in the sun. That's it!

  • How much money do I save?

    The average period using tampons and pads costs $240 a year. Scarlet costs about $120 a year (five pairs) and can last anywhere from 2 years to 10 years depending on how you take care of them. So let’s say they lasted for 5 years, you’d spend only $120 as opposed to $1200 on pads and tampons during the same amount of time. Wow.

  • How often do I need to change them?

    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.

  • Can I wear them all day?

    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).

  • Can I mix and match different styles?

    Yes! Create a set tailored to you using our 'create a set' tool.

  • Do they smell?

    Nope! If you wash them properly and care for them they will not smell.

  • What if I don't love them right away?

    If you don't love them, or are unsure about sizing - let us know. We will help you out. We also have a 60 day first-purchase guarantee. Email us at support@scarletperiod.com for any concerns or questions with your purchase.

  • Can I buy just 1 pair?

    Based on customer feedback, we've updated our pricing and our packs to enable you to get bigger savings and better rewards when you shop for period underwear. However, if you really only want 1 pair just email us at hello@scarletperiod.ocm and we'll help you out 😊
