Key Features to Consider
When it comes to choosing a smart water bottle, there are a few key features to consider.
Volume: The bottles in this collection range from 12oz for quick sips to 32oz, which is ideal for all-day use. If you prefer to avoid constant refills, a larger bottle will be better. But if you want something easy to carry around, smaller-sized bottles are more portable.
Types of lids: Do you prefer easy sipping from sporty spouts or leakproof flip lids that you can toss in bags? Many companies provide interchangeable covers, allowing you to customize your drinking experience for the gym, work, or travel.
Materials: Do you love having ice-cold beverages for hours on end? Insulated stainless steel works perfectly. If you enjoy your water at room temperature, glass and plastic options are available as well. Some people prefer the refreshing metallic chill, and others prefer something lightweight that won’t create puddles on their desks.
Best Water Bottle Overall: Hydro Flask Standard Mouth (24 Oz)
If you are searching for a combination of style, performance, and durability, then the Hydro Flask Standard Mouth bottle should be at the top of your list. One of the best 24-ounce bottles, this one features outstanding TempShield insulation, allowing drinks to stay icy cold for 24 hours and hot for 12. The outside is made of stainless steel and, in addition to keeping dry, feels good to hold. It also comes with bright colored powder coats that can match your style.
