How it works

The 8-Hour Solution: 
Drink 1 glass per hour for 8 hours

By measuring water in hours (rather than ounces) Hourglass makes it easy to know when to have a drink. Simply keep an eye on the time to stay on track—if you fall behind, drink up! 

Eight glasses of water. One glass bottle.

Our bottles are made from shatter-resistant borosilicate glass. Lightweight, easy to clean, and crystal clear as water.
