Don't let the price fool you, this insulated bottle is worth every penny. I have never owned another reusable bottle that keeps beverages cold for such a long period of time. It can be in my hiking pack, in the blazing sun all day , and still have ice in it for the trek down the mountain.
I was so impressed with the results that I purchased two more Kleen Kanteen insulated bottles. They have saved us serious cash by keeping them in the fridge and grabbing them whenever we hit the road - no more plastic bottles! I would totally recommend this product.
