>>1960168>the idea being that a load closer to you won’t produce as much leverage and will stay closer to your center of gravity over very rough terrain.It also lowers the center of gravity by extending the pack down to your ass, whereas external frames usually sit higher up and have open space on the bottom for a sleeping bag or mat. Lower center of gravity is alright when you're climbing, not so much when you're walking up right. Shifting center of gravity means one tend to start countering the pull backwards by leaning forward.
>It can’t get taller. This puts the carried weight further from your center of gravity.No, guess why people in primitive societies carry heavy shit on their head.
