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.

Was recommended this by my sister and I love it. It keeps my tea warm for my whole shift on these cold wintery mornings. It is easy to clean and love the colour also!
I was on the lookout for a new bottle as I have so many plastic ones laying around, and I find stainless steel doesn't retain flavors or have that weird taste like plastic bottles do. It's great at retaining cool temps (haven't tried hot yet), looks cute, hasn't leaked for me and I even bought the separate strainer so I can add in fruits and etc! I love my bottle.
Excellent quality water bottle. My drink stays ice cold for the entire day. Very happy.
I purchased one each for my partner and I, really great quality water bottle, everything is sturdy and replaceable if you ever happen to break something. Love that even the seal is replaceable. I get compliments all the time and have recommended it to everyone.
Love this water bottle - easy to clean. Keeps cold. Use it for golf and given many as gifts.
Fabulously Cold So impressed with this bottle and how cold it keeps the water. By the end of the day the water was as cold as it was when I left home. Awesome product and I highly recommend it.
Water in the bottle stays cold. I work in the heat and hate hot water in my normal bottle. This is a great product. Water stays cold for hours with a few ice cubes. My kids ask for my bottle as it’s so nice to drink out of compared to normal bottles. My Sigg Bottle is going into storage.
The first time I used my Eco Vessel I couldn't believe how long it keeps my water cold, my ice was still frozen 24 hours later! Perfect for the aussie heat! I have recommended to all my family and friends! 5 Stars!
This is the best insulated bottle I have ever used, it keeps my drinks cold all day long and fits in the car cup holder! I love the interchangeable lids too!
I love it and so do my teenagers! Perfect for school!
I love my new EcoVessel bottle! It has a nice wide mouth which is ideal for filling it up and it's amazing how long it keeps my water cold.
I lose time in the morning and never get to finish my smoothie. This is the perfect size for my smoothies on my commute to work.
This is the best bottle I have ever used and keeps cold for a really long time! Love it!
