I am always taking water with me wherever I go, because I can't count on being able to find a good source of water like I have at home. You can never tell where the water comes from when you purchase a pre-bottled water in the store. I prefer my own so I like these Unibott water bottles. They are BPA free, BPS free and EA free...free of the chemicals that leach into the water from other plastic containers. If you leave your commercially bottled water in the sun in your hot car, you won't want to drink it because of the chemical leach. This bottle is shatterproof...great idea. To keep a good grip on the bottle they have a silicone sleeve over it and a silicone wrist strap on the cap. The cap secures the liquid inside. I prefer to have a flip up sipper on my bottles but this one works, too.
I received this product at a discount in exchange for my honest and unbiased review.
