How do EQUA bottles react to thermal changes?

Both EQUA glass bottles and stainless steel bottles can handle big thermal changes - from -10 up to 90 degree Celsius. EQUA SMART and EQUA CLASSY THERMO are built with a double insulation (triple wall) and can carry your cold drink for up to 24h or hot tea for up to 12h. As for the glass Mismatch bottles, they also offer thermal protection with their felt and faux-leather covers.
