The Boulder vacuum insulated water bottle is our flagship bottle that will keep your drinks hot or cold all day long. Made from premium 18/8 stainless steel, it features our signature TriMax® Triple Insulation and keeps drinks cold up to 74 hours and hot up to 14 hours. The Reflecta™ lid is insulated and lined with stainless steel, enhancing temperature retention and preventing drinks from ever touching plastic. The dual-opening lid is easy to grip, has a wide mouth for easy filling and a soft silicone spout for a comfortable drinking experience. The lid is securely attached to a sturdy carrying strap, so you always know where it is and the leakproof seal keeps your drinks in the bottle - where they belong. The Boulder stainless steel water bottle also includes a removable strainer for tea, fruit and ice cubes. The fitted silicone bumper adds protection against everyday drops. Plus, choosing a reusable water bottle cuts down on single-use plastic consumption. There’s nothing the Boulder doesn’t offer! Keep the Boulder in your car cup holder or toss it into a tote and bring it to the gym, on the trails or to work to stay healthily hydrated through the day.
