One Top fits all: Like all other SIGG caps, the sports top fits on all SIGG classic traveller style drinking bottles and makes a practical addition to each SIGG, particularly when the drinking bottles are used during athletic activities.
The drinking spout can be easily opened and closed with your mouth to keep it leak proof while on the go!
