Take this striking tumbler in all four directions and on the road less traveled. Its dual-toned and distinct finish is as sophisticated as your Airstream; likewise, it performs beautifully, made of double-wall stainless steel with vacuum insulation and copper plating. The push-on lid with drink-through opening keeps things neat even when "the highways and byways of the world" get a little bumpy. Fill it up and set your course for exploring.
