The Boulder Insulated Stainless Steel Water Bottle is our flagship thermal hydration vessel that will keep your drinks hot or cold all day long. Made from food grade 18/8 stainless steel and featuring our signature TriMax® triple insulation technology, this vacuum insulated stainless steel water bottle is tested to keep liquids cold for 40 hours and hot for up to 12 hours.

The BOULDER stainless steel water bottle features a food grade stainless steel removable strainer for tea and fruit infusion. The strainer will also work well as an ice dam to keep your ice in the bottle instead hitting your teeth. The Boulder stainless steel water bottle includes a dual-use top with a wide opening for easy filling and a spout for easy drinking and pouring. For added versatility and value, the top is interchangeable with our push-button coffee top and flip spout sports top which are offered separately. The two-piece lid includes an integrated carrying strap and its secure leak-proof seal will keep your drink inside the bottle where it belongs. It’s available in a variety of colors and styles in our durable powder coated finish or in a stainless steel finish. Your bottle won't sweat and will fit most cup holders.

    The "Vessel of My Dreams"

    I cannot begin to share how many Yetis I have, and none of them could do what my Boulder can! I go camping several times a month, and I can literally fill my Bolder up and have ice almost the entire duration of my weekend trip! Thank you so much for this genius invention!!!

    My Favorite!

    A co-worker found an EcoVessel three years ago and returned the bottle to our office. I claimed the bottle and it’s been next to my side 24-7 for the entire three years. The bottle fits in car cup holders, lays perfectly in my purse, has a handle for easy carry, keeps my ice cold for days, and has an easy spout to drink out of while driving. I travel often so these conveniences are significantly important. I’m sooooo thankful for this find and I now own five EvoVessels. Your products have been a lifesaver. X
