So you thought you’d do something good for yourself, and you bought one of those trendy aluminum water bottles that has an earth friendly design on it. You’re saving some cash by carrying a reusable bottle; you’re saving some sea turtles by not contributing to the Great Pacific Garbage Patch; and your shiny, lightweight bottle is saving YOU from looking like a wasteful jerk at the gym. Awesome, right?

Only if you really don’t care about your health. At Hydro Flask^® we design our bottles based on a fact that is lost on anyone who dates a Hollywood socialite: Just because something is lightweight and shiny DOES NOT mean it’s good for you!

Aluminum fights with calcium for absorption by bones in the human body, leading to osteopenia and the more widely known osteoporosis. If that’s not scary enough, aluminum is a known neurotoxin, which means that it damages nerves and nerve tissues. And although it is not yet conclusively linked to the onset of this disease, aluminum has been found to be at elevated levels in the brains of Alzheimer’s victims.

It has become standard practice to coat the inside of aluminum drinking bottles with a water-based resin to protect the fluid inside from leaching anything harmful from the bottle. But have you ever considered that your skin, which absorbs aluminum readily, comes into much more contact with the outside surface of that bottle? Sure, the interior coating might keep your fluids safe from an aluminum bottle’s innards, but as you handle a brushed aluminum bottle to fill it, drink from it, or carry it, what’s happening to YOUR innards?

Hydro Flasks are made from 18/8 stainless steel that is food-grade, lightweight, non-porous, and 100% recyclable, right from the outset. There are no nasty minerals or BPA in our bottles, so that means there will be no nasty minerals or BPA in you. Your wallet will thank you; the sea turtles will thank you; and most important, your body will thank you.
