What's great about EcoVessel is everything about them. First off they are in the business of hydrating people, but they also care about the planet. They give a lot back to several non-profits like Water For People and Leave no Trace. They are committed to staying green and helping to eliminate single-use water bottles.
They also have very thoughtful design. Like a built in grip, an ice strainer, and rubber bottoms to prevent spilling. Top that off with 3 layers of insulation and these bottles offer so much more than a cool drink.
