Perfect Lunchbox Bottle

  • Familiarity: I've put it through the wringer

We were desperate for a lunchbox bottle that wouldn't leak anymore (sick of cleaning out sour milk from their backpacks). This was perfect - 6 and 8 yr old kids can screw and unscrew without help. Easy to clean, right amount of liquid and fits into lunchbox perfect. Kids bang them around and we have some dents but bottle holds up well. We're very happy and will buy some adult sized ones too.

Best Insulated Bottle

  • Familiarity: I've put it through the wringer

I have had several Eco Vessel bottles and use them constantly, both at home and at work. I can put a drink with ice in the bottles, and they are still cold days later. The bottles have a hardy construction, and can take a lot of abuse. Highly recommended!

Best Bottles for Your Favorite Tea

  • Familiarity: I've put it through the wringer

Fantastic Bottle, bought it in all 3 sizes, 17 oz, 25 oz, and 45 oz. 17 for keeping a fresh drink handy around the house and yard, 25 for short excursions, and I especially like the 45 because I can cold or hot brew tea that is available to me all day. The strainer makes it particularly nice for cold brewing my favorite herb teas, with lots of flavor and no bitterness.

fitness gal loves this water bottle!

  • Familiarity: I've put it through the wringer

This is the water bottle I bring with me to the gym. I love that my water stays cold!! It's taken a beating too and still looks great. Just a couple dings, but I think that adds character!

Great product.

  • Familiarity: I've put it through the wringer

Keeps things cold for at least 2 days and I love the strainer which keeps the ice out of my mouth. I use mine every single day. Highly recommended.

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
