Used by pros and amateur athletes, our SiS Wide Neck Sports Bottle features our unique Easy Mix System combined with a wide neck opening that takes the hassle out of measuring and pouring powder. Pre-determined measuring marks printed on the outside of the bottle enable you to pour specific amounts of SiS powders without any guesswork.

The bottle’s 600ml size holds just short of a pint of fluid and its standard diameter ensures it fits easily in bicycle water bottle cages. An ergonomic design makes it easy to grab when you’re continually reaching for it to take in fluids during endurance exercise.

For use in the gym or out on the road, the bottle has a leakproof, lockable valve so you don’t have to worry about losing any valuable fluids to keep you performing at your peak.
