The Contigo West Loop travel mug bundle includes a 24oz and 20oz stainless steel mug, both featuring Contigo's patented Autoseal technology for a 100% leak-proof and spill-proof design. The mugs' vacuum-insulated double walls retain heat and cold, keeping drinks hot for up to 5 hours and cold for up to 12-18 hours depending on size. With sleek metallic finishes and rubberized grips, these mugs provide convenient one-handed operation for drinking on-the-go. Their lids automatically seal between sips to maintain optimal drink temperature. The lids also pivot open for easy top-rack dishwasher cleaning. Combining different sizes allows you to choose the right capacity for your needs, whether carrying a quick coffee to work or a larger beverage for longer trips. The durable stainless steel construction ensures these mugs will withstand daily use for years, while their compact shape fits most car and single-serve brewer cup holders. Together, the Contigo West Loop mugs provide a portable, spill-proof system for transporting hot and cold drinks. Their innovative lids eliminate messes, and vacuum-insulated bodies retain heat and cold for hours of enjoyment from your favorite beverages. With convenient cleaning and drinking, these mugs simplify your busy, on-the-go lifestyle.
