The BOULDER vacuum insulated water bottle is EcoVessel's flagship bottle that will keep your drinks hot or cold all day long. Made from premium 18/8 stainless steel, it features EcoVessel's signature TriMax® triple insulation and keeps drinks cold up to 60 hours and hot up to 12 hours.

The Reflecta™ lid is insulated and lined with stainless steel, enhancing temperature retention and preventing drinks from ever touching plastic. This 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.

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.
