Used by pros and amateur athletes, the SiS Narrow Neck Sports Bottle features the unique Easy Mix System 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 800ml size holds a large supply 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 during training and competing.
