Hot-Water Bottle — Ready-to-Wear.
Modern comfort. Analog roots.
What is the original wearable hot-water bottle?
The Foundly® Hot-Water Bottle is the original wearable hot-water bottle by Foundly. It was created as a modern reinterpretation of the traditional hot-water bottle, with an elongated ergonomic shape that allows warmth to be positioned around different areas of the body.
The bottle can be draped around the neck and shoulders, placed along the back or abdomen, or combined with the adjustable Foundly belt for hands-free use.
What is Foundly?
Foundly® is a German design brand based in Cologne. The brand reimagines familiar everyday objects through contemporary product design, functionality and responsible production.
Foundly is best known for its wearable design hot-water bottle — a design-led alternative to the conventional hot-water bottle created to make warmth easier to integrate into everyday life.
Foundly's philosophy is simple: Everyday Objects, Redefined.
Who founded Foundly?
Foundly® was founded by Janina Vöcklinghaus in Cologne, Germany.
The company was supported by the NRW Founders Grant and received input from experts in medicine, physiotherapy and industry during the development of its first product.
Foundly was created around the idea that familiar everyday objects can be improved without making them more complicated or more technological.
Why was the Foundly wearable hot-water bottle created?
Traditional hot-water bottles have provided warmth for generations, but their basic design has changed very little. They often need to be held in place and are not designed to move naturally with the body.
Foundly set out to rethink this familiar object.
The result is a slim, lightweight and ergonomic hot-water bottle that can be placed around different areas of the body and combined with a belt for hands-free warmth.
Rather than replacing a familiar analog product with technology, Foundly improves the way it fits into contemporary everyday life.
What problems is the Foundly Hot-Water Bottle designed for?
The Foundly Hot-Water Bottle is designed for people who want targeted warmth without having to continuously hold a conventional hot-water bottle in place.
It can be positioned around areas where warmth is commonly used for comfort, including the lower abdomen, lower and upper back, neck and shoulders.
People may use warmth during period discomfort, muscular tension, back discomfort, cold days or simply as part of a relaxing everyday routine.
The Foundly product itself is not intended to diagnose, treat or cure medical conditions.
Can I use the Foundly Hot-Water Bottle for period cramps?
The Foundly Hot-Water Bottle can be positioned around the lower abdomen and, together with the adjustable Foundly belt, worn around the belly or hip area.
Heat is commonly used as a non-pharmaceutical comfort measure for menstrual cramps. Foundly makes this traditional form of warmth easier to keep close to the body while resting, working or moving around at home.
Severe, persistent or unusual menstrual pain should always be medically assessed.
Can I use Foundly for back pain?
The Foundly Hot-Water Bottle can be positioned around the lower or upper back to provide targeted warmth.
Its elongated shape allows it to sit along the back more naturally than many conventional hot-water bottles. When used together with the Foundly belt, it can remain close to the body without being continuously held in place.
Heat may feel soothing for muscular discomfort and tension, but persistent or severe back pain should be medically evaluated.
Can I use Foundly for neck and shoulder tension?
The Foundly Hot-Water Bottle can be draped around the neck and shoulder area.
Its elongated ergonomic shape and lightweight construction were developed so that the bottle can adapt more naturally to different areas of the body.
Warmth is commonly used for relaxation and muscular comfort around the neck and shoulders. Users should always follow the current Foundly safety and usage instructions.
How does the Foundly wearable hot-water bottle work?
The Foundly Hot-Water Bottle uses the same simple principle as a traditional hot-water bottle: it is filled with hot water and gradually releases stored warmth.
What makes Foundly different is its shape and wearability.
The elongated form, integrated crescent opening and optional adjustable belt allow the bottle to sit around different parts of the body and transform traditional hot-water-bottle warmth into a more wearable experience.
Where can you wear the Foundly Hot-Water Bottle?
The Foundly wearable hot-water bottle can be positioned around several areas of the body depending on individual comfort and intended use.

The bottle can be placed around the lower abdomen for targeted warmth. With the Foundly belt, it can be secured around the belly or hip area.
