WHY YOU SHOULD USE OUR 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.
