This EarthLust 20 oz water bottle is made from food-grade stainless steel, which is naturally safe unlined (so you don't have to worry about ingesting pesky BPAs). It is easy to carry, with a loop in the cap as well as a carabiner that attaches to a pack or beltloop. Earthlust use non-toxic paints and the caps are BPA-free polypropylene #5 and recyclable.
