## Description

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 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 leak proof 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.

Review: I don't leave home without this bottle. It's so nice to come back from a long hike to have ice cold water waiting for me in the car (even on 90 degree days!). The design is great and I love the no slip silicone bottom.
Review: The bottle is beautiful and has no taste transfer. And finally a bottle where water doesn’t come in contact with plastic! Bottle came without the protective bumper. Ordered another one and same thing. Love the bottle but my other two came with bumpers, I currently have 4 in total. The company rectified this with a refund so I appreciate the customer service.

I recently switched to an EcoVessel stainless steel water bottle and have been quite pleased. The insulation keeps my drinks cold throughout the day, and the build quality feels solid and durable. The design is sleek, fitting easily in my bag without leaking. I also appreciate the removable strainer, which is handy for adding fruit or ice. Overall, it’s a reliable and stylish bottle that meets my daily hydration needs.
