ECO Vessel

  • Familiarity: I've put it through the wringer

I love this bottle so much! I found it in a little shop in Door County and after using it had to buy another on line. I use mine for water and it keeps the water cold for a few days...even keeps it cold in a hot vehicle. You need this! It's amazing! Love the handle for an easy carry. It doesn't sweat either.

Best Insulated Water Bottle Ever

  • Familiarity: I've put it through the wringer

The best insulated water bottle I have every found. Everybody in my family has one. It encourages us to drink more water. Keeps it cold all day long without leaving annoying watermarks on the surfaces. Fits well into our on the go lifestyle. Fits into the cup holder in the car so I can take it with me. The sturdy handle means I can clip it to my bag or backpack while on the go. Staying hydrated has never been so easy as it is with Eco-Vessel.

Big fan

I live in Colorado and spend a lot of time outside. When you're fishing on the river, it sucks to drink warm water when it's hot out. Eco Vessel keeps my water cool all day. Double like

Insulation Surpassed Expections!

I wasn't sure what to expect when I bought this bottle without knowing much about Eco Vessel...but now I'm a believer! The built-in tea strainer works great to catch ice and the bottle still had ice in it when I got home after 8 hours of hiking. I wish this 17oz version held a little more water, but for tea or coffee its perfect. 5/5
