Insulated Water Bottles

How does an insulated water bottle work?

The insulated bottle, or flask, relies on a double stainless-steel wall separated by a vacuum that blocks heat transfer. The result: a hot drink stays hot and a cold drink stays cold for many hours. Up in the mountains during winter, a hot tea is a real comfort; in summer, cold water feels brilliant after a tough climb.

Capacity and how long it keeps its temperature

How well a bottle holds its temperature depends on the quality of the insulation and its capacity: a larger volume keeps the temperature better. Choose according to your needs: a small bottle for an occasional hot drink, or a bigger model for all-day use. Compare with classic walking water bottles, which are lighter but have no insulation.

A stainless steel bottle, tough and watertight

Stainless steel is the material of choice: long-lasting, neutral in taste, and resistant to knocks on the trail. Check that the cap is completely watertight to avoid leaks in your rucksack, and look for an opening that's easy to drink from and to clean. A well-designed bottle stands up to years of adventure without affecting the taste of your drinks.

What's it for?

Perfect for the mountains, winter walks, wild camping and hot weather, an insulated bottle is heavier than a basic one - so it's the right choice when the temperature of your drink really matters. You'll find it in our walking accessories range. Whether you're camping, travelling or out in the open air, a double-walled stainless steel bottle is a must-have: the key to a drink at just the right temperature, mile after mile.
