Before I get an uproar about SIGG's , let me point out that SIGG bottles are lined with a new that does not contain any BPA. If you want to know whether or not your bottle's liner contains BPA, check the inside: if it looks metallic and has a coppery color, it's the old kind; if it's a matte, pale yellow, it's the new EcoCare liner.
No BPA? Check. Reusable? Check. Which brings me to my next requirement: Am I gonna have to take a hammer to my ice cubes to get them into my water bottle? Not with SIGG's new . The new model features a dual mouth that unscrews in two pieces, allowing both a wide mouth that fits ice cubes as well as the classic, smaller mouth for easy drinking so I don't get a face full of water when I'm trying to walk and drink at the same time (it's harder than it sounds).
My only complaint is that the Wide Mouth bottle doesn't have the variety of designs that the traditional models do, but then again, my matte-black finish and corrugated siding looks pretty badass as it is.
