Best Reusable Water Bottle

  1. Iron Flask Sports Water Bottle

The double-insulated Iron Flask water bottle has something for everyone, regardless of age, body type, or budget, and is available in a plethora of size and color options (6 of the former and 23 of the latter). Each water bottle comes with three different lids for switching between hot and cold beverages, ranging from 14 ounces to a bladder-busting 64 ounces. Yes, the Iron Flask can keep cold things cold for up to 24 hours and hot things hot for up to 12 hours.

Aside from one stainless steel lid and one flip lid, the third lid has a built-in carabiner clip for attaching your beverage of choice to a backpack or bike rack. The 40-ounce size felt a little unwieldy in my adult-sized man’s hands, and I imagine the 64-ounce model would be even less mobile. The powder coat finish is slick-looking, but if the outside is wet, make sure you have a good grip on it. Because this water bottle is sweat-free, this is only an issue if you’re sloppy when filling it.

The double-walled insulation is designed to keep drinks ice cold for up to 24 hours or piping hot for up to 12 hours, according to the company. The Iron Flask is up to the task with its eye-catching color options, various lid options, and a wide range of liquid capacities.


  • There are three different lids included.
  • They are numerously available.
  • No sweat insulation
  • Priced reasonably


  • When wet, it is simple to drop.
  1. LARQ Bottle Movement PureVis

The LARQ Bottle Movement PureVis is more than just a mouthful to say: it’s a cutting-edge water bottle with a built-in self-cleaning UVC LED light. When activated, it can remove up to 99.9999% of bacteria and 99.99% of viruses from your drinking water; the 280 nanometer UV light (similar to those used in hospitals) causes a photochemical reaction within the bottle to destroy germs and viruses like E.coli and Salmonella. The LARQ Bottle Movement PureVis is made of electropolished stainless steel (with a silicon sleeve) and is available in six different colors.

The silicone sleeve is also slightly grippy, making it difficult to tip over the bottle when it’s full. (Some water bottles, especially those made of steel, can be top-heavy.) The LARQ Bottle Movement PureVis comes with a MicroUSB charging cord and a quick start guide, but for $78, an extra silicon sleeve (or some kind of carrying pouch) would have been nice. You can personalize the bottle with up to 10 uppercase characters for an additional $15.


  • UVC LED light built in to kill germs and bacteria
  • Keeps drinking water fresh Personalization options are neat


  • No insulation
