The BBB ThermoTank BWB-52 is a bottle with double wall construction and 3M insulation material. It keeps your drink cool or hot up to double as long as a normal bottle. The BWB-52 is made from dishwasher safe and BPA free polypropylene material and can hold up to 500 ml / 18 oz. It is easy to squeeze and makes cleaning and filling simple, due to its wide opening. The special AutoClose valve is lockable when needed, but can also stay open to make drinking very easy and will still be closed to prevent spills on the bike.
Material: polypropylene
