I did a search on "hot and cold therapy products" and there are a lot of them but if you'll notice on this site:

https://www.healthproductsforyou.com/c-hot-and-cold-therapy.html

Almost NONE of them are very portable and NONE of them combine portability within a single product for both "hot" and "cold".
