Backpack is already under my legs... I also used to stuff gear like rain jacket into a stuffbag with some extra clothes but all this kit has shrunk and shrunk over the years - my storm jacket is now the size of a tennis ball, wind jacket even smaller, and top quality down (when not wearing it already as part of a "sleep system") compresses extremely well. Fleece makes a good cushion too but again, my fleece is mainly for camp and night use. All this is not a big deal for an overnighter but on longer trips, my first priority is carrying (nice!!!) food for 6 or 7 days. My
valveless inflatable pillow is mainly for those nights when other pillow substitute options are exhausted.
