As seen on tour, SiS Pro Yellow Bottle is a water bottle designed for fuelling for long periods of exercise and features our unique Easy Mix System and wide neck opening for the effortless dispensing and mixing of SiS powder supplements.
WHY YOU SHOULD USE THE SIS PRO YELLOW BOTTLE
Our iconic Pro Yellow Bottle was originally designed to be used with energy supplements developed by Science in Sport Performance Solutions in collaboration with British professional cyclists. Still our pro-issue bottle, it has a large 800ml capacity with an ergonomic design that makes it easy to grab and hold, while its leakproof and lockable valve ensures you don’t lose any valuable fluids during exercise.
For convenience, the bottle features our Easy Mix System which consists of pre-determined measuring marks printed on the outside of the bottle enable you to pour specific amounts of SiS powders into the bottle that remove any guesswork and save you time.
