For style or plainly for holders, water bottle totes are common nowadays for people who want to stay hydrated. And while we see a lot made of neoprene, here is one made by NeoGreen, the insulated water bottle tot.
With twice the insulation value of traditional Neoprene, the new Neogreene Insulated Water Bottle Totes have a soft, stretchy fabric which makes it easy to load and unload your water bottle. The cinched collar accommodates different neck sizes, while the low-cut front ensures you can drink from any reusable bottle that fits in the tote.
Neoprene (polychloroprene) is a synthetic rubber developed by DuPont in 1930.
