Know before you buy
The Cold1 Mug features dual-wall vacuum insulation that keeps beverages cold for up to 40 hours. Performance may vary slightly depending on the ambient temperature and how often the lid is opened.
The 3-position lid is designed for versatility, allowing you to sip, drink, or gulp. While it is secure for everyday use, it is not 100% leak-proof, so it is best to keep the mug upright when traveling.
Yes, the Cold1 Mug is dishwasher safe. Its 18/8 food-grade stainless steel construction is durable enough to withstand standard dishwasher cycles without compromising the insulation or finish.
The base is specifically engineered to fit most standard vehicle cupholders. However, because cupholder sizes vary by car model, it is a good idea to check your vehicle's dimensions if you have an unusually small or non-standard console.
The Soft Sit™ base provides a non-slip, cushioned bottom for the mug. This protects your furniture from scratches and prevents the mug from sliding or making loud noises when you set it down on hard surfaces.
No, the Cold1 Mug is made from high-quality 18/8 food-grade stainless steel and is completely BPA-free, ensuring your drinks remain clean and free from unwanted chemical leaching.
