Sometimes we’ve gotta look back at where this crazy ride started almost 50 years ago in 1974. Fresh from the vault, this unique design was born during our founding days and now we’ve brought it back for today’s riders. Grab one of these limited-edition Special Eyes bottles and your own piece of Specialized history.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.
