The In Layers Collection captures the expansive beauty of nature and the peaceful bliss of space while bringing attention to climate change. As the day warms, and you remove layers, the In Layers Collection mimics the patterns of global temperature rise.The Purist MoFlo Bottle features an amorphous silicon dioxide coating that's infused into the inner-wall of the bottle. Essentially, this forms a glass-like finish that provides a totally natural, and completely inert, solution to the problem of your drinks staining the bottle or leaving behind any residual aftertaste. This infusion also shields your fresh water from tasting like plastic on very hot days, making it akin to drinking straight from a sparkling clean glass.
