Drinking from a glass bottle is key to getting the purest and freshest taste of water. The problem is that glass tends to be breakable and unsafe to travel around with. The Asobu Bottled Up water bottle gives you all the benefits of glass with none of the cons. The inner chamber and spout is made with double walled glass while encased in shock resistant Tritan wall and reinforced with silicone bumpers. The spill proof lid keeps the air out and the freshness in, making it a great travel or on the go choice for kombucha or juicing.
