Flashlight, compass, paper map, 4x MRE stripped to essentials (I swap these out once a year, and eat MREs once a year for 4 days), 2 mags for each of the I could have had them on me freedom dispensers, 2 mags for the long version freedom dispenser that is with the bag. filled camelback (rotate the water monthly if sealed properly and check inner liner), passport book, a small amount of cash, first aid kit, 2 lifestraw, a pocket knife (i dont always carry one), a few single edge razor blades, 100' para cord, poncho and liner (old school USMC version), fire starting devices, spare brace for lower back (old age setting in, and i dont wear it often, but hiking i like it), 3A armor (no hip plates or anything fancy, just back and chest plates, which are due for replacement next year). comes out to about 35% of my body weight. a bit much. but its not humping half my weight for 25 miles a day for 2 days, which sucked balls, but damned if my commander didnt want to have one under his units belt for bragging rights. Not to count the 6 weeks we did single 18 milers once a week and the 2 weeks we did 18s twice a week with barracks at night in prep. All in all, I can still live with 35% if I've got to march for a while. I wont go as fast as I used to, or as far, but I can still go.
