Made of high-grade aluminum in one piece, the Balance Flask is lightweight and highly practical. The easy to use turn cap holds tight, even when filled with carbonated beverages. The high-elastic inner coating is resistant to fruit acid, taste neutral, and free of BPA, as well as phthalates. With a capacity of 0,6L, the flask easily packs away into any bag and holds enough water to keep you hydrated during outdoor day hikes or indoor gym sessions.
