Water is essential for life and ever since the dawn of time living things have depended on liquid water to sustain life. Water is an ideal beverage for any time of the day, and now more convenient than ever with the reclosable lid. No need to fumble around looking for a drinking glass and a tap (or spigot) because all the hard work is already done for you. An ideal way to replace lost fluids. I found the taste to be a little watery.
