Hydro Flask Trail Small Mouth Bottle (21 oz)

25% lighter than their standard bottles, Hydro Flask's Trail series have 18/8 pro-grade stainless steel walls that are thinner to reduce weight while maintaining durability. They will still keep your beverage of choice ice cold for 24 hours or piping hot for 6+ hours, and you get no condensation on the outside of your bottle.

The Trail bottles also have a lighter weight Flex Cap with an internal honeycomb insulation and perforated flexible strap.
