The Hydaway travel bottle is genius, it fits the needs perfectly of the busy, financially conscious, economical and environmentalist. Always buying water is convenient but it adds up quick, how many times have you been at the airport and needed water, costing you more than $5.00 a bottle. This reusable pocket bottle folds up easily and can even be stored in your pocket, it takes no space at all in your bag or pocket. Coming in 2 sizes, 600 ml or 350 ml never be left high and dry! Stay hydrated, protect the environment and keep that hard earned money in your pocket (with the hydaway safely tucked in it as well of course).
