Your questions, answered

What is the rae?

rae is our signature heat pad that goes wherever you go. The soft-feel silicone pad heats to a comfy 50 degrees – with three settings – and sits silently and discreetly. Think of it as a 100% reusable and recyclable alternative to bulky wheat bags, hot water bottles, and stick-on patches.

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.

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 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. But they are great for rae, as well as holding cold packs. Oh, and snacks. They’re great for holding snacks.

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.

What do the different underwear levels mean?

Our Period Pocket Underwear comes in two absorbencies. Level 1 (Light—Moderate) absorbs 3 teaspoons of fluid (roughly equal to 2 regular tampons or 1 regular pad) and level 2 (Moderate—Heavy) absorbs 5 teaspoons of fluid (approximately equal to 3 regular tampons or 2 regular pads).
