Soi Body is committed to sustainability through the materials we use as well as maintaining small production runs. 

Our hot water bottles are 100% Natural Rubber which are biodegradable, when disposed of correctly.

Our covers are made out of 100% Cotton which again is biodegradable after they're no longer suitable for their original use, when discarded thoughtfully.

Importantly, the usage of hot water bottles only requires access to hot water, and requires no microwaves or battery power to create heat. And once the water becomes room temperature or cold, it is safe to pour the water onto your indoor plants, garden or into waterways with no impact to the environment, creating a circular use of our precious water resources.
