  1. Best Insulated Bottle

    Posted by VAL PITTS on 20th Feb 2018

    Love this bottle. Bought two, keeps my water iced cold for a very long time.I actually left it on the kitchen counter, open, and the ice was still in it the next day!

  2. Fantastic product & great gift!

    Posted by CDC on 27th Dec 2017

    I've loved my EcoVessel bottles for years. I am never without one (usually my 45oz). This year I purchased 8 to give as gifts at work. The purchase was somewhat selfish in that I want to see less disposable water bottles. The recipients were impressed with the quality. On staff member said, "this is the real deal and I need to hide it from my wife". He was impressed with how it kept his coffee so hot, for so long. No sweating. No leaking. I LOVE EcoVessel!

  3. Boulder water bottle ROCKS

    Posted by Jeff on 24th Oct 2017

    This is our third Eco Vessle. I think the Boulder is the Perfect size. Keeps ice for 2 days/2-3 refills.
    No plastic, aside from drinking spout. The best Water bottle I've used, and I've tried a few. Fill opening and drink spout is just right size wise. Keeps my drinks cold. super neat and fun to drink from.

  4. Pro and Con

    Posted by Cmd on 1st Sep 2017

    I've had an older version of this bottle for a number of years. The main pros for me are how well it keeps my water cold. having the smaller opening to drink out of, the screen keeps the water from gushing into your face when you are really thirsty... and even though I've dropped it on concrete, the dents do not keep it from it's great insulation properties. My main and only "con" is the loop carry top - it works great AND it doesn't last - it's not as durable as I expected... I've had to replace it several times as the material begins to 'crack' from opening to drink and holding it out of my face. My original bottle is useless to me even though the water bottle works etc., they no longer make a loop cap that fits it so I have no way to carry it conveniently. My suggestgion is to purchase several loop/caps when you purchase your bottle so you know you are covered down the road!! Surely in this day/age a material could be used for the loop that would by much longer lasting.....

  5. Best Insulation and Design.

    Posted by jtienlau@yahoo.com on 5th Aug 2017

    Had bought both white a Boulder and stainless Big Foot a few years ago but sadly lost my Boulder and the Big Foot is too big for the car cup holder. Because of the price of Ecovessel, I tried a couple of other brands which were good but not comparable to the Ecovessel in the temperature retention. Came back to the Boulder which has been redesigned with straight sides than the old curvy ergonomic shape. Also, the white color has not been available over the past months. Still, the excellent insulation, cap loop and texture are as I terrific as I remembered.

  6. Coolest bottle we got!

    Posted by Unknown on 26th Jul 2017

    Awesome product! Great thermal isolation and decent price! However, on hot summer days when your hands are sweaty, it's impossible to get a grip on the screws!! If they offered something with better grip, I'd definitely order it!

  7. Favorite bottle

    Posted by Unknown on 23rd Jul 2017

    This is my new favorite water bottle. I love the top, easy to drink out of. Water stays cold for a long time. I had to contact customer service about my order (I messed up) and they were awesome. Super helpful and really nice. I will definitely be getting more bottles from Ecovessel!!

  8. The best water bottle I have ever owned...

    Posted by Unknown on 10th Jul 2017

    It is everything I always wanted. It keeps my water cold all night long.

  9. What's not to like about it??

    Posted by Jeanene Lathrom on 10th Jul 2017

    There are many reasons I love this bottle:
    1. It fits into the cup holder perfectly in my car.
    2. It keeps drinks ice cold for HOURS!
    3. I can throw it into my tote bag without having to worry about it spilling on my way to work.
    4. The mouth of the bottle is just the right size for taking a big swig of your cold beverage.
    5. I loved the color choices available!
    This bottle is a great purchase!!

  10. My New Favorite Water Bottle

    Posted by Unknown on 20th May 2017

    This bottle is great - it is the perfect size. As a longtime user of the Summit bottle with straw, this bottle is ideal as I was looking for one without a straw.
