The Foundly Hot-Water Bottle is the upgraded version of the conventional Hot-water bottle. Ergonomically shaped (including massage riffles) and designed to keep you warm and cosy during your daily routines – whether it’s at the office, during outdoor activities or while having a relaxing rest at home. In combination with our comfy, removable belt, our hot-water bottle can be worn in multiple ways: around your neck and shoulders, around your upper or lower back or around your belly.

Studies have proven that heat in general has a similar effect to a painkiller, effectively “deactivating” pain at a molecular level. In this way, completely naturally and without any chemicals, heat shuts down the regular pain response and helps with issues such as menstrual pain, neck tension, and abdominal cramps, and even diseases such as endometriosis or Crohn’s disease. However, hot-water bottles by themselves do not ease pain. UCB does not claim the capability of a medical device. In case of doubt, consult your doctor or pharmacist.

Yes. The fact that heat relieves abdominal pain, such as colic or menstrual pain, has been scientifically proven by a UCL (University College London) scientist. Dr. Brian King, of the UCL Department of Physiology, led the research that found the molecular basis for the long-standing theory that heat provides relief from internal pains.

Please note also the Terms and Conditions.

Please do not fill your Urban Cross Bottle from a tap or other domestic water system as this can prematurely degrade the product. After usage, allow your bottle to air dry completely with the lid open. This will help to avoid unwanted moisture build-up. Store your bottle with the lid off and keep it in a cool, dry, dark place. Avoid contact with hot surfaces, oil, grease, direct sunlight, pointed and sharp objects. Do not allow anything to rest on the bottle. It is advisable to replace your rubber bottle every 2 years.

The UCB holds 800ml. Nevertheless, it is recommended to fill the bottle only to a maximum of 2/3 or less to avoid burns. Don’t forget: Do not use boiling water; even hot tap water can scald.

When filling your hot-water bottle, do not use boiling water. Fill it to a maximum of two-thirds capacity, expel air, and check for leaks.

This recommendation is for your protection as hot water can cause burns. Doctors recommend 40-50 degrees Celsius as the ideal water temperature.

Natural rubber is produced by the rubber tree (Hevea brasiliensis). It’s biodegradable and has a lower environmental impact than synthetic rubber. Foundly uses natural rubber in its products to ensure the highest quality and sustainability standards.
