The Original Classic Steel Water Bottle

The name couldn’t be more fitting for the original stainless steel bottle that’s been around for 20 years and still going strong. Designed to last a lifetime, these lightweight, non-insulated, single-wall water bottles have kept people hydrated and happy since 2002, as the first metal hydration bottle on the market. With a narrow profile for easier gripping, packing and carrying, this iconic bottle is proof that reusables never go out of style. While many things have improved and changed (profile, sizes, colors, caps, and our Klean Coat finish), our Classic bottles remain the go-to choice for hydration, with sport, loop and other all-stainless cap options. Also check out our Insulated Classic bottles to keep drinks ice cold or hot.
