>>2679223If you're sleeping, plan on packing heavy and hiking shorter days. Or hike base-camp style where you set up camp and venture out, return at end of day, repeat for as long as you have food. Boiled water bottle in your bag really works wonders, I've made it through nights that were too cold for my bag doing that. Also hand warmers work great in your sleeping bag. Get an insulated pad, I've gone down to ~5F with a 4.5r inflatable + 2.0r foam.
