Science Behind the Coolness

The genius behind insulated bottle holders lies in their double-wall design. Expertly crafted, these holders consist of two layers of material separated by a space. During the manufacturing process, this space is voided of air, creating a vacuum.

Why a vacuum, you may wonder?

Well, it turns out heat transfer is far less effective in a vacuum than it is in air. This means the vacuum acts as a barrier, slowing down the rate at which heat from the environment can reach your drink. The result? Your beverage stays refreshingly cold (or deliciously hot) for significantly longer than it would in a traditional holder or glass.

This science magic works on any beverage, from a frosty beer to a chilled soda. Whatever your drink of choice, it will remain at the perfect temperature, just the way you like it, for hours on end.
