Adapt your Sigg water bottle so it can be used with a SteriPEN Journey or Classic water purifier
Food-grade silicone adapter slips onto the top of your Sigg bottle, allowing you to use your SteriPEN Journey or Classic water purifier.
With the adapter installed, simply activate your SteriPEN, insert it into your Sigg bottle and flip the bottle upside down to purify your water.
Adapter also protects your lips from the cold touch of aluminum in freezing temperatures.
