    Instant heat packs

    These are fantastic 👏. My daughter was cramping quite badly just before leaving for work. The heat pack took the edge off and enabled her to go. When she got home hours later it was still warm!

    These heat packs are amazing! I’ve never seen anything like it. So easy to use, sticks on, and gives off a lovely gentle heat all day. I am buying more!

    Heat Pack

    These heat packs are incredibly useful and versatile. I love how convenient they are to carry around, and they’re always ready to use whenever I need them. There's no hassle of filling a hot water bottle and worrying about spills, and I don’t have to search for a microwave to heat up a wheat pack. The best part is that they’re super discreet—no one knows I’m wearing one, so I can enjoy the warmth and comfort without feeling self-conscious. Perfect for on-the-go relief!

    Life-Changing for Period Cramps!

    This heat patch has seriously changed my life. I used to dread my periods because the cramps were so intense, and going to the gym felt impossible. Now, if I wake up with cramps, I just slip on my high seamfree period undies, stick a heat patch on, and pull on my leggings – no one can even tell! I can finally get through my day (and my workout!) inn comfort. This has made such a difference in my routine, and I actually feel ready to tackle the day. Can’t recommend it enough!

    These literally have changed my life

    For the past 5 years I have had really bad pains from endo. My friend gave me one of her heat patches last week to try out, wow, it made me feel so much better. I got them with the pocket pants and am now feeling so comfy and free. Previously I didn't want to leave the couch on day one and two but now I can. So happy with these patches. FP, can you do a subscription program with these as I am going to need them all the time. I will probably use about 3 per period so if there was an option to get some every 3 months, I would sign up.

    Instant Relief That Goes Wherever I Do!

    I can’t believe I went this long without the Fanzy Pantz heat patch! It’s the perfect size and sticks right where I need it without shifting around. The warmth lasts for hours and really helps with my cramps—I can finally get through the day without feeling miserable. It’s so easy to use and much more convenient than a hot water bottle. Whether I’m at work, out and about, or just relaxing at home, this patch has been a total lifesaver!
