s 32 oz adequate? It depends entirely upon the environment. In the American desert southwest right now, 32oz is inadequate, unless you end before 9AM and have potable water immediately handy. On the California Channel islands, 32 oz is good for an entire day of hiking and some will probably not be consumed.

Variable include body size, water content of any food consumed, and quantity of skin exposed. i like to pay attention to electrolytes, as well.

It is far better to carry too much, rather than too little. Three guesses as to how I learned that.
