best reuseable water bottle

I have this one from under armour: http://www.amazon.com/Under-Armour-Dominate-Insulated-Stainless/dp/B0053RWBSO

It's awesome. Water is still cool at the end of the day, I can throw it in my bag without worrying about it leaking or sweating all over my papers, I've even put it in the dishwasher a couple of times if it gets funky. I went through several kleen kanteens (sweats a lot, doesn't stay cold, dents like crazy if you drop it, and the tops always seem to leak no matter what I do), siggs (same problems as the kleen kanteen, although less leaky and denty) and nalgeens (don't really leak, but don't stay cold either) before I found this, and now the rest are all in a pile in my cabinet. Highly recommended and would buy it again (have considered getting a backup, actually).
