I was going to use Sigg originally but after research I decided that I wanted a bottle without any sort of inner liner, and in it's past history Sigg had issues with theirs, leaking BPA's, I am unsure whether that issue has been resolved and decided to get a bottle that is pure stainless steel, not aluminum and without inner coating of plastic. The Glogg is great, you know you have a safe bottle and they are durable. Great company to buy from. Their bottles could do with some stylish designs on the outside like Sigg, hopefully that will happen eventually.
