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.
