SIS Drinks Bottle

A clean, fast, and convenient way to prepare and use SiS drinks
This bottle is specially made for SiS, with handy markings that are a key part of the easy-mix system
To use, start by adding drink powder up to the appropriate level; part fill with water and shake to mix the drink; finally top up to the final level with more water
The result is no fuss, no mess, with less chance of contaminating your drink
An wide opening makes it easier to pour in powder from larger tubs
