Built from BPA-free 18/8 stainless steel, this bottle resists oxidation and corrosion, helping maintain a clean taste and reliable performance over time. The interior is designed to minimize lingering odors and metallic notes, so beverages stay true to their flavor with minimal aftertaste. Double-wall vacuum insulation slows heat transfer, keeping hot drinks warm and cold drinks cool for extended periods while the outer surface remains comfortable to the touch. A secure leak-proof lid and a robust seal reduce the risk of spills when carried in a bag or backpack. The wide mouth opening simplifies filling, pouring, and cleaning, and it accommodates ice cubes for chilled beverages. The design supports everyday use in home, office, or on the trail, whether you are hiking, camping, or commuting. It serves practical purposes such as replacing disposable cups and cutting down on waste while supporting a reusable hydration option. Durable construction and materials contribute to long-term reliability and easy maintenance in varied environments. The exterior typically remains free of condensation, keeping grip dry and comfortable during use. Color: Gold. Material: Glass.
