pepxo PEXPO Espresso 1000 ML Tri-ply Vacuum Insulated Steel Bottle 3X, 1000 ml Flask 1000 ml Sipper  (Pack of 1, Pink, Steel)

The temperature in Pexpo Espresso stays the same because of the tri-ply tech and vacuum insulation combo used in the manufacturing of this bottle. The layers of tri-ply tech work together with vacuum insulation to maintain the temperature of the beverage. This is why you always get the beverage as hot or cold as you had filled it. There is an extended benefit of the above triply tech. The above-mentioned aluminum layer has a coating of stainless steel under and over it; thus, it is called triply or three-layered tech. The presence of stainless steel ensures corrosion resistance and does not let the beverage get spoiled. Pexpo uses SS 304 for this.
