    Boulder Bottle

    Excellent product for both hot and cold drinks. Ice lasts for hours and hot drinks are still ****** hours later as well. Also consider the 24 ounce size for a little bit extra.

    Love these water bottles!

    We've been using Eco Vessel for a few years now but it was time for larger bottles for my children. They love them! We bought the flip top this time, also, and they are so excited about them. Thank you, once again, Eco Vessel! I love having a water bottle that is safe (non-toxic), highly functional and easy to use for the kids!!!

    A great experience!

    Have had an Eco vessel 20 oz Boulder for some time. Really like it so decided to get one each for my grown children for Christmas gifts. Purchase process was quick and simple, and I received my bottles within five days. Thank you!

    Exercise at the Y

    This bottle goes with me on Monday and Friday to my senior exercise class. I like the new wider mouth because I can put a couple of ice cubes in with my water.
