Huggable soothing companion
100 day returns | 2 Year Warranty
A safe way to keep your body warm as well as relieving stress, muscle and joint pain.
Heatbag is much more than a heating bag. Warm it up and it will become the perfect companion while lounging on the couch or while sleeping tight with warm feet. Freeze it and it will become a safe pain relief.
With a recycled memory foam cover lined in a soft jersey fabric, hugging Heatbag creates an immediate sense of happiness and helps relieve stress.
Its unique composition of eight layers and two differentiated sides ensures that the heat is released slowly and focused on the desired spot, preventing you from getting burnt by cold or heat.
Hot & cold therapy has never been easier to do.

To heat simply place the clay bag in the microwave and heat it at 1000W for 55 seconds.

"Love them, got another one , for under my feet ( they get easily cold)"

"Very sophisticated upgrade to the classic waterbag, its versatile heat-retaining clay is sheathed in a smooth, pleasingly hued fabric cover. Retains heat a fairly long time. Haven't tried cold function yet. Time to microwave will vary depending on microwave so test it out as instructed. Very comfortable to hold."
— Valery C. (5/5)
"I was already familiar with this product as I had purchased it before for my mother."
— Erin H. (5/5)
"This bag is amazing and when it’s warm in bed I love nothing more than a clay out of the freezer."
— Julie P. (5/5)
"Warmer, more comfortable, and safer feeling than a traditional rubber or silicone water bottle. Keeps the heat well and even when cooled it never feels cold. Tip: I found that heating in the microwave for the recommended 55 seconds wasn't warm enough for me. A bit of experimentation and I settled on a much toastier 1 minute per side (1 minute then turn over and repeat) in an 800w oven."
— David W. (5/5)
"Konnte ich leider noch nicht ausprobieren. Fühlt sich aber sehr furchtbar an und ist wirklich gut verarbeitet!"
— Brigitte F. (5/5)
"Very good at relieving my wife's back pain"
— Thomas M. (5/5)
"Im sorry but it was purchased as a Christmas present and has not been opened yet. But I was very pleased with the delivery."
— maurice w. (5/5)
"I have to say I expected more from this after reading the reviews. I found that it doesn’t warm up consistently. The edges of the heat bag get quite warm but the middle part doesn’t; I have tried increasing the heat in 10 second increments in the microwave, as suggested in the instructions, but it doesn’t seem to make much difference."
— Andy M. (3/5)
"It just arrived a few hours ago and I'm already obsessed with it. I will be buying a spare. Would make a fantastic gift too."
— Laura W. (5/5)
