Your Questions, Answered

Umm, what is rae?

rae is THE heat pad that’s here to go with your flow. Designed in Australia, rae is slim, soft, and curved for extra comfort. With three heat settings and flexible wings that hug your body, it’s USB-rechargeable, splash-proof, and fits right into our custom period undies pouch.

Can I use the undies without rae?

We’re not here for rules, so you do you boo! They do have additional fabric for the pocket at the front so if not using with rae, you might prefer our Bikini Brief or High-Waisted Brief.

Can I use rae without the undies?

rae is designed to get hot, so we do recommend using rae with them or otherwise over your undies. If using directly on the skin, start at the lowest setting and monitor your comfort.

How do I wash them?

After use, rinse them in cold water (we recommend in the shower) until they run clear. Then, machine wash in cold water with mild detergent (no bleach!). Try our Laundry Bag to safeguard them on laundry day. Then just hang out to dry (the sunnier the better) or tumble dry on low - that’s it!

TIP: If it’s your first wear, pop them in the washing machine with your next cold cycle - washing them before wearing activates their absorbency even more.

How do I pick the right size for me?

We get it, sizing for bottoms is anything but standardised. Which is why this size guide will help break it down for you. Make sure to check both our numeric and letter sizing so no confusion (ie. our large is a 12).

When in doubt, feedback tells us better to size up. Still confused? You can also email us for help at support@scarletperiod.com.

What does the absorbency level mean?

Super Light: Holds up to 1 teaspoon, which is equal to less than one regular tampon. Think of it as a new-age panty liner, so it’s great for spotting, light leaks and discharge. Try: Invisible Thong

Light: Holds up to 3 teaspoons, which is equal to 2 regular tampons or one pad. This is for light days to save you from pesky drips, discharge, and lighter flows. Try: G-String or Bikini Brief in Light-Moderate

Moderate: Holds up to 5 teaspoons, which is equal to 3 regular tampons or 2 pads. Go for this on moderate days or as extra defence on heavy days with our Period Cup. Try: High-Waisted Brief or Bikini Brief in Moderate-Heavy

Heavy: Holds up to 7 teaspoons, which is equal to 4 regular tampons or 3 pads. Our heavy hitters are great to wear on their own, day or night. Try: Boyshort or Period Cup

Very soft

Very soft. Keeps heat pad close. Smart buy!!!

Reliable and practical.

I forget they're period underwear. They wash well, dry quick, and feel normal under clothes.

Good on heavy days

I need real coverage. These stayed comfortable through work, gym, and errands. Wore over 8 hrs no worries

Really soft and nice to wear

The pocket design works exactly how it should. I wore them on a long day out and didn't worry once.

A very clever product

I bought these for heavy days and honestly didn't expect to trust them as much as I do. The pocket detail is genius. I've since ordered more.
