Choosing the right insulated water bottle doesn’t have to mean choosing the most expensive one. Try to focus instead on picking a water bottle that best meets your needs, whatever they may be. Embarking on a day hike? Going camping with your family? Leaving on a kayak expedition? Mountaineering with your best friend? No matter what you’re doing, there’s a water bottle for it. 

The majority of insulated water bottles stay hot for 6 to 12 hours and stay cold for between 6 to 24 hours. Choosing a water bottle also comes down to the size of your backpack, car or kayak. Most people will carry a water bottle in the side external pocket of a backpack, or store it in the cup holder of a car or kayak. You’ll therefore need to measure the width of your backpack pockets or cup holders to know which water bottle is right for you. Now, let’s review eight of the best insulated water bottles.



Hydro Flask Standard Mouth Bottle With Standard Flex Cap - 24 oz (709 ml)                              

The Hydro Flask Mouth Bottle is our clear winner for the best insulated water bottle, as it performed well in every category we tested.

What sets it apart from other bottles is its durability and TEMPSHIELD insulation feature. This double wall, vacuum-insulated technology protects temperatures from outside elements. It keeps drinks cold for up to 24 hours and hot for up to 6 hours.

The beauty of the Hydro Flask is that there’s no condensation or heat transfer to the outside of the bottle. Another important feature of the Hydro Flask is that it's made out of pro-grade stainless steel, which protects against flavour transfer, so that your water won’t taste like yesterday’s protein shake.

A durable, sweat-free powder-coat finish ensures you can always maintain a solid grip on it. The bottle easily stashes into your pack’s side pocket or vehicle cup holder. At 24 oz (709 mL), it also holds enough insulated goodness to keep your beverages fresher for longer.
