Insulated water bottles

Insulated bottles for the outdoors and everyday life

Drinking a warm tea to warm yourself up during a hike, climb or ski session, or having some hot coffee to invigorate your senses is very enjoyable. If you want to carry hot drinks all day long, then insulated bottles are the way to go. Not only can they be safely stowed away, but it won't leak in your backpack, plus it ensures your drinks are still very hot hours later. In addition to being great for hiking, ski touring and other mountain activities, they're also very practical in your everyday life. You can bring your favourite drink to school, uni or work and have it quickly accessible at all times.

High-quality insulated bottles, like the ones from Mizu, Thermos or Camelbak, can keep liquids warm or cool for up to 24 hours. Depending on the bottle and the outside temperatures, this time may be longer or shorter. If you fill an insulated bottle with hot tea in freezing temperatures, the contents won't stay warm for as long when compared to filling the same bottle on a leisurely hike in summer temperatures. While bottles for adults usually have a plain and functional design, you can find super colourful insulated bottles for children.

Construction and function of insulated bottles

An insulated bottle has a vacuum inside that provides insulation. The outer wall is usually made of stainless steel or plastic, and the inside is made of glass or stainless steel. Since the vacuum inside does not conduct heat very well, your tea, coffee and hot water will remain hot for a long time. They also have a reflective layer on the inside to reflect the heat.

Insulated bottles often come with a lid that also serves as an insulated cup. This lid can either be made of plastic or stainless steel. Under the lid, you'll find an actual closure, which is screwed on tightly and often has a practical spout system. A lot of heat can be lost through the cap of an insulated bottle. As a result, high-quality bottles manufacturers insulate their lids to prevent as much heat as possible from escaping.
