Insulated tumblers, flasks & bottles
An insulated bottle or flask is the product you need to keep your drink cold or hot on the go.
Thermal bottles and flasks are generally all 100% leakproof, so your choice may be made based on how long your drink will stay hot or cold. This depends on the insulation system (like double wall) and the brand (Thermos, THERMOcafé, Qwetch, etc..).
MaxiCoffee has a good range of insulated products including tea infusing bottles, travel presses, tumblers, flasks... with different sizes to suit your needs.
