The Stanley Adventure Multi Use Bottle is your answer for a stainless steel travel bottle that has a bit more design consideration and function. It features a twist off body that converts to a cup, volume markings, as well as a regular quick drinking spout. Also, I imagine twisting it apart makes it that much easier to clean compared to the traditional steel/aluminum bottles with narrow necks, which require a cleansing tablet to thoroughly sanitize. Holds 32 oz and is dishwasher safe.
Available from Amazon, 9.88.
