I actually felt like I was dying before I found this. It's really been super convenient, especially because I can hide it super easily under my clothes during class (though I do think it looks pretty cute on its own)! I bought one for my roommate and she rly likes it too! :3

My boyfriend bought this for me and it genuinely might be the best gift ever! I usually spend the first day of my period curled up on the couch. Love that I can just put this on and go about my day. The heat feels SOO nice.

Was honestly a little skeptical at first but was pleasantly surprised by how much I like it. The massage feature is a nice bonus and I can wear it while doing stuff around the house. Been a big help these past couple months!

Frequently asked questions

Everything you need to know about WarmBelly, shipping and returns.

Can I use it if I have endometriosis or PCOS?

Lots of women with endometriosis, PCOS and other causes of painful periods use heat for comfort on their hardest days. WarmBelly makes that heat wearable: steady warmth and gentle vibration that can help cramp days feel more manageable, whether you’re at home, at work or out.

Everyone’s body is different, so results vary. That’s why every order comes with our 100-Day Money-Back Guarantee, so you can try WarmBelly without the risk. WarmBelly isn’t a treatment for any condition, so talk to your doctor about managing endo or PCOS.

How long should I wear it?

Wear it for as long as it feels good. Start on a low setting and try to take a break between sessions.

How is it different from a hot water bottle?

A hot water bottle starts hot and cools down, so you keep refilling it, and you can't take it to work. WarmBelly holds the heat level you pick, straps on hands-free and runs on a rechargeable battery, so you can wear it at your desk, on shift or in class.

What's included?

The WarmBelly heating pad with its adjustable strap, a USB-C charging cable and a user manual.
