Hydro Flask Wide Mouth
This is as well-made and effective a water bottle as you will find. And it’s one of the originals. Of course, it’s made of 18/8 stainless steel that won’t rust, has double-wall construction for insulation, and it’s powder-coated for grip. Now industry standards, those enhancements are all innovations that Hydro Flask revolutionized. And, it comes in a multitude of sizes, colors, and styles.
