Boasting enough capacity to fuel your next big adventure, the 24 oz (650 ml) Lightweight Trail Series bottle is 25% lighter than the other 24 oz wide mouth bottles in the Hydro Flask range thanks to an innovative stainless-steel design. The wide mouth design delivers the same practicality and cold refreshment without the weight penalty, making it easy to transport icy-cold, refreshing drinks as far as your spirit of adventure takes you.
