We bought two of the West Loop bottles. One in orange, the other in matte blue. Unfortunately, the two different versions seem to be. The orange has the normal "Seal" closure, the blue an additional caps lock and inside the option pop up the mechanism for cleaning. The newer version is more practical and sanitary.
Otherwise, both cups are super, the coffee stays hotter for longer, after four hours, he is rather lukewarm and not hot as the manufacturer promises.
