We think Bruce Wayne takes his water in this cool looking insulated drink bottle. Adam West probably does so too. After all, it has TherMax double wall vacuum insulation for maximum temperature retention. Kid-proof design: unbreakable stainless steel interior and exterior withstands daily wear and tear. This thermos also has a hygienic push button lid with a pop-up straw reminiscent of the thermos bottles from the 1970s (Click on the inset to see an image of the flip-top lid & straw). The base is non-slip and scratch resistant. Holds about 12 Oz. (355 ml). Measures about 7.5" tall, and 2.5" in diameter at the base. Fits into most metal, plastic, and soft insulated lunch boxes. For cold and room-temperature drinks only. Shipping Weight: 3 lbs.
