Then I came across these Lifefactory bottles at Whole Foods one day -- a glass bottle with a silicone sleeve for better grip and handling as well as a loop screw-cap. It definitely encourages me to consume more water while I'm working during the day without worrying about wear and tear. This bottle also allows for easy care and cleaning -- I usually just throw in the bottle and the cap into my daily dishwasher load. Highly recommended!
