Awesome water bottle

I was given this water bottle as a gift and have been using it all summer long. I use it for water and it keeps it cold all day. Also, really like the soft silicone mouth piece. Would highly recommend and plan on buying a few for Christmas presents.

Super Well Designed, Great Value

I've had the 20oz Boulder for some time now but really wanted something larger for longer excursions. This 32oz is perfect. EcoVessel features the handy carry loop and a free drop boot -- something I had to buy separately for my HydroFlask coffee thermos.
