Best one-liter water bottle
The only stainless steel bottle on our list, this vacuum-insulated bottle will keep your water cold up to 28 hours, complete with a built-in straw to sip from. Stainless steel does have its advantages over plastic, especially when it comes to durability: it’s practically impossible to break.
You can also unscrew the lid and add ice, too. But it’s best to avoid putting hot liquids in the bottle, which can create pressure.
The Simple Modern bottle’s lids are leak-proof, and the lid, which features a hook, is also ideal for gripping with a few fingers and taking around the gym or to the car. The company donates 10% of its proceeds to charity, which we love. Just keep in mind that the one-liter size likely won’t fit in a cup holder (other sizes are available).
These bottles also come in a variety of colors and designs, as well as additional sizes, ideal for men, women, or even children (the brand makes special patterned ones for kids).
