Best flask for formula feeding

[Eliza2901]

Hello! I’m ff and can’t seem to find a flask that keeps water above 70 degrees for more than 2 hours. Completely useless fir going out! Can anyone recommend a good one? Currently going out is ridiculously stressful. Thanks

Thermos do a brilliant one that keeps hot water hot for 12 hours and cold things cold for 24 hours. It holds it at a good temperature over night we found so I'm sure it would manage 2 hours.
