The 21 ounce vacuum insulated Hydro Flask Standard Mouth Insulated Water Bottle with Sport Cap is our most versatile medium-sized water bottle and one of our most popular. It is the perfect go-anywhere companion on your busiest days. Stainless steel water bottle fits most ice cubes and is easy to drink from for hydration on the go.

This sports water bottle is also compatible with our Standard Mouth Flex Cap. This Hydro Flask product is backed by a manufacturer's lifetime warranty.
