One for all: The 3 Stage Sports Top from Sigg fits on all the drinking bottles made by the Swiss manufacturer. The leak-proof top is especially practical when you are doing sports.
The 3 Stage Sports Top has its name from the three-stages it is opened with: First of all it must be turned, then pulled out and finally it is open for you to drink. The top by Sigg is absolutely leak-proof in both “bottom” positions, which is especially practical when you are outside or doing sports.
The Sigg 3 Stage Sports Top has big advantages for children, since it avoids pouring the content accidentally and it saves your nerves.
