>>858596>>858700>carabiners attached to shoulder straps for 2 point attachment of top or bottom loaded secondary bag.are you this fucking daft?
I used to poorfag with a backpack, for over a decade. a carabiner on each shoulder strap, and bam, you have all the anchors you need to attach a bag on top or below your main load, not to mention since you are two points, the load shift is mitigated.
