Lead- and BPA-free enamel, under 3 ounces empty, clips to a pack strap for the hike in. Hand-wash only, not dishwasher or microwave-safe, and skip heating liquids directly in it since that can damage the coating. It'll stain from coffee and tea eventually. Lemon juice and a sponge take it back off, if that bothers you.
