BKR is a glass bottle with a silicone sleeve. Not only is a BKR bottle beautiful, but it's small mouth helps you not spill your water down your front. Your BKR can be put in the top rack of the dishwasher. BKR bottles are durable - but it is glass. Treat it like you treat your cell phone. Carefully!

Glass is inert and does not leach chemicals. BPA, found in plastic bottles, has been linked to an increased risk of cancer, obesity, early onset puberty and diabetes. Tap water is yummy and almost free, not to mention cleaner than bottled water, with stricter standards for purity. It's also conventient, as it's from your tap, not a mountain in Fiji.
