Does anyone have a recommendation for a single cup thermos flask?
I use a GSI Microlite (12oz/350ml) thermos. It checks the boxes mentioned (stainless steel/good seal/double wall). No leaks so far (2yrs old). [https://vpo.ca/products/microlite-350-flip?Color=White&Size=-](https://vpo.ca/products/microlite-350-flip?Color=White&Size=-)

Stainless Steel Food Storage?
These are more for keeping temperature on a hot lunch, but i've had good success with GSI's tiffins.

ISO: Strong Insulated Water Bottle
[GSI Microlite](https://gsioutdoors.com/pages/microlite-insulated-water-bottle). My partner wants drinks to be as cold as physically possible for as long as possible and I found this. It’s been dropped plenty of times over the last five or so years and it’s all dented up, but it still works great.
