turning a berghaus centurio mmps 45l into a 75l for hiking, camping, and bushcraft versatility

i was looking into how i could make my rucksack lighter and only discarded one item out of a mmps 110 litre bergen. so took thr rocket pouches off to make it 90 litres.but still no good. so i was looking around for a new smaller rucksack, about 70 to 80 litres. digging around in deep thought, i eventually thought about this idea. #hiking #wildcamping #bushcraft #backpacking #military #mmps
