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.

How hot does rae get?

It has a built-in thermometer, so it maintains the heat level depending on the heat setting you are using (up to 50 degrees). We suggest always starting on a low setting until you get used to it and find the right heat for you.

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.

Won’t rae just fall out of my pants?

Nope, because we’ve come up with a genius solution. Meet our Period Pocket Underwear: a customised version of our best-selling period underwear with a little pouch for the device, perfect for when you’re on the move.

Attached to your regular undies? No problem! Wear rae between your underwear and clothing. If using it directly on the skin, stick to a lower heat setting.

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.

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

Love It!

I bought a heat pad for my daughter who suffers from very painful endometriosis. She loves it! It doesn't get as hot as a hot water bottle, but is very comfortable and soothing. Great invention!

Amazing but a struggle with hand strength.

The Scarlet Rae is amazing—I just wish I’d had it before my hysterectomy. I still get pelvic pain, and this has been a game-changer. It’s discreet, mobile, and so much better than being stuck to the couch with a corded heat pad. Unlike a wheat bag, it stays in place tucked into leggings.
My only issue is the power button. With some hand strength problems, I struggled to turn it on at first and thought it was faulty—my husband managed it easily. I can usually get it now, but it still takes a few tries. If you have hand issues, just be aware of that. Hopefully it’s something they improve in future versions.

Changed my period.

Best heat pad I have ever used. I bought two so I leave one at work. It is just really good and I would highly reco to anyone with a bad period. I do hope they bring out normal undies with the pocket as would like to use off my period as well.

Game changer

Stage 4 endo girly, this is amazing! The touch of a button and it heats. No more boiling the jug for constant hot water bottles!. Only thing I’d ask for is a place in the case to put the charger.
