The SIS Clear Branded Water Bottle Wide Neck 600m is a clean, fast, and convenient way to prepare and use SiS drinks. This bottle is specially made for SiS, so it has handy markings down the side that are a key part of the easy-mix system. They let you fill your bottle to precisely the right level for the correct concentration of drink and powder.
This bottle has an extra wide neck to make measuring out and filling even easier. It also means it'll be easier to clean, so you always get a great-tasting, contamination-free drink.
