Having a piping-hot drink outside in winter or an icy cold beverage in the summer is a luxury, a mood lifter. I’m not going to claim that the GSI Glacier bottle will improve your climbing, but I will say that it brings you good cheer. This stainless-steel thermos keeps drinks hot or cold all day. Last summer it even had ice left over from 24 hours earlier. In winter when I filled the bottle with boiling tea, I actually had to let it cool in the rubber-coated screw-off mug before I could drink it. A fine trick: crunch up a pack of Ramen noodles, add the chemical/flavor pack and boiling water. The noodles will cook in the bottle. Out at the ice climb or cold crag you’ll have a hot meal with carbs and a hot drink with electrolites all in one swig. Disadvantages? The one-liter version is heavy at 23.5 ounces empty. I still carried it, always. If weight is an overriding concern, the bottle is available in lighter, if smaller, versions from 17-ounce capacity to half liter.
