Open Water sells still and sparkling water in both aluminum bottles and traditional cans, with a case of 12 bottles costing $27 online, or $1.59 per bottle in stores.

A 16-ounce bottle of Open Water retails for $1.49 to $1.99, putting its price on par with premium waters like Evian or Fiji, said the company, headquartered in Chicago’s Bridgeport neighborhood.

The twist-to-open nozzle took a minute or two to get used to, but the process quickly became second nature, and it was much more secure than flip-up versions like the Vapur Wide-Mouth Anti-Bottle.
