Whether you're a wave watcher or a wave rider, the totally awesome Hurley® Oasis Travel Mug is the perfect choice for hot or cold beverages. Made of food-grade 18/8 stainless steel, its double wall vacuum insulated construction and copper lining provide extra temperature retention to keep your drink cold for at least 30 hours and your hot drink hot for up to 12 hours. This mug offers a large 40 oz. capacity for fewer refills and the large side handle makes it easy to grip. The lid features 3-in-1 functionality for sipping, swigging or slurping and the included straw fits snuggly into the silicone opening and is designed to resist splashes. The Oasis has a narrow base that will fit in most standard car cup holders and its durable powder coated finish helps prevent surface scratches. FDA compliant and BPA Free.
