The Water Bottle Parka by Outdoor Research. This insulated bottle carrier lets you transport hot or cold liquids into the backcountry. It weighs much less than a thermos, but offers similar performance. A reinforced nylon strap with a hook and loop closure allows it to attach to any pack and an updated design fits most modern day water bottles.
