As a family we started very heavy years ago and ended up at 68 pounds total for three packs for a week in the mountains. 28, 22, 18.
That is impressive indeed!!! Figure 1.5 pounds of food per person per day makes that roughly 32 pounds in just food! So just gear is down around 36 pounds. Everyone using 4 pound packs makes that down to just 24 pounds of stuff besides you are putting in your packs!! After taking 5 pounds out for spotter and tripod and another 4 pounds for 3 pairs of binos you are looking at less than 15 pounds split 3 ways for the gear you need to survive, or 5 pounds per person. Raingear per person around 1.5 pounds, sleeping bag/quilt another 1.5, sleeping pad another .5 and either a puffy coat or baselayer for additional warmth when needed and you are there. Of course shelter and cooking stove and fuel comes into play there, but very doable for sure. Very well done indeed.
Of course omitting rifle and water weight, trekking poles all help for sure when starting out helps, but regardless that is impressive!
