Unique, lightweight, and attractive ... these are just three of the comments we have received about the Jordan&Judy Crater series hydration bottles. We designed the Crater series with a slightly thinner glass wall to save on weight, but still provide the durability you would expect. The dimpled (or cratered) texture, along with our soft eco-friendly silicone sleeves, provide a sure grip no matter how you hold it. The Crater bottle is made high grade Borosilicate glass, free from BPA, BPS, Lead and Thalates, giving you an uninhibited pure taste for any beverage you choose to put in it. Stay healthy and hydrated with the Crater bottles from Jordan&Judy!
