Gear Tip: Klean Kanteen Insulated Bottle I like equipment that serves more than one purpose. I’ve found that in the Klean Kanteen insulated bottle. It’s my extra water bottle, my camp mug and my thermos all in one. It’s a double walled bottle, not a thermos. The big difference here is that it holds more liquid for it’s size. No, it’s not quite as insulated as a thermos but I still seem to have hot tea 4 hours into a cold high altitude climb. The 16oz size also makes a perfect camp mug. They even sell a mug top for it separately, but I don’t see the need for it personally.  Sometimes I only really want to carry 1 ½ liters of water on a climb so the 16oz insulated bottle is perfect along with one of the non-insulated one-liter bottles. Klean Kanteen makes a full line of metal bottles that are a safe BPA-free alternative to plastic bottles. Check them out at: Klean Kanteen by Dave Miller IAG/CAG Director
