Here is a great Eco Water Bottle! These are made of re-claimed materials (scraps that would have been destined for the dumpster from other manufacturers), and the items are made with the earth in mind. Although the materials will vary (from recycled hypolon and vinyl to natural rubber mats with insulating qualities), their purpose remains the same! Additionally, the manufacturer of these bottles will donate 1% of the sales to Leave-No-Trace to educate and facilitate the responsible enjoyment of our planet.
