Vostok | Double Walled Insulated Stainless Steel | 34 oz
I have tried several stainless steel filtered water bottles and this is the best. It is very easy to get the water to come through the straw and it holds a lot of water. I do wish it would fit in my cup holder, but I'm still happy.
I have been using this daily and makes life so much easier! No more spending money on water bottles because you can fill it any where!
