Finally, SIGG has recognized the fundamental flaw they've always had -- the thin mouth. No, I wont be trashing my Klean Kanteen anytime soon, but if there was a way to conversion, this would be a great first step.
I HATE it when the water bottles mouth isn't wide enough to put ice cubes in it. I mean who wants to crush those up just to cool down the water? SIGG FINALLY came up with a solution and made a wide mouth reusable bottle. I am SOOO getting one!!
