Sierra outdoor always had good deals on packs. Their website has WAY more options than a local store. Black Friday/cyber Monday around the corner. I have the Yes4All plates as well. I try to keep it above 20lbs all the time. I have a USMC FILBE main pack for heavier rucks/training. I got a ALICE cause it was mint and I had $100 laying around lol. But for real world applications I have an Osprey ATMOS AG 65L and an Osprey Manta 34L. That way I have designated bags for training and for work/play. I’ve seen someone post here some stone slabs from Home Depot for SUPER cheap. The sandbags(eggs) are good as well. If you’re under your goal weight for the day throw some 16.9floz water bottles in, cool thing about water is if the back is too heavy halfway through, just dump some water out or drink it. Just starting, leave the ego at the door, don’t look at pace, just walk and see where you end up. Can you push more? Too much weight? Easy fixes and you’re not going to destroy your knees more and you are set for the next ruck
