Great Sigg design and quality, 17 Sept. 2013
Had my sigg for the last 18 years and always used the standard bottle top. Was recently looking for something to make it more usable as a gym bottle and this did the trick.
Looks the part, fits my old sigg perfectly, and it doesn't leak even when rolling around in my bag. It's definitely less hard wearing than the standard bottle top, but then it has a different function entirely. I would recommend to anyone wanting to turn their sigg into a gym flask.
