Applied Nutrition Cooler Tumbler Cup, Blue - 1200 ml

The Applied Nutrition Cooler Tumbler Cup is a 1200 ml double-wall vacuum-insulated drinking bottle that keeps your beverages at the exact temperature you pour them — whether that's ice-cold water during a workout or hot tea on a cold morning. Vacuum insulation is an engineering solution also used in professional thermal flasks: an air-free gap between the two walls blocks heat exchange with the environment.

According to the manufacturer, the Cooler Tumbler Cup keeps cold drinks cold for up to 11 hours or more and works equally well with hot beverages. This makes it a versatile companion — suitable for the gym, office desk, car, campsite or longer journeys. The generous 1.2-litre capacity means you can often get through an entire workout or working day on a single fill.

How does vacuum insulation work?

A regular bottle has a single wall through which heat quickly dissipates — cold drinks warm up within an hour or two, and hot drinks cool down. In a double-wall vacuum bottle, there's an air-free gap between the two walls. Since heat travels mostly through molecules, the vacuum (absence of air) blocks this transfer almost entirely. The result: drinks stay at a stable temperature several times longer than in a regular bottle. The same technology is used in the best hiking and sports thermos flasks.

Care recommendations

Rinse the Cooler Tumbler Cup with warm water and mild soap before first use. For everyday cleaning, hand wash with a soft bottle brush and dish soap. The bottle is not recommended for dishwashers or microwaves, as high temperatures and the mechanical wash cycle can damage the vacuum insulation. After washing, dry the bottle thoroughly to prevent odours.
