Not sure what to call this thing.
Its intended purpose is to add a bit more cpacity to my existing pack and is designed around a 5 liter dry bag.
I would probably put some lighter stuff in it, like clothing or something, in order make room in the pack for a few more heavier things.
Bungee webbing utilizes existing D rings on the bottom and loops around the pack side compression straps.
Pocket thingy sewn out of old duffel bag parts with the addition of three SS banner grommets from work.
Made a velcro topped pocket and successfully pulled off my first attempt at sewing in a liner.
I won't mention the part where I had to dismantle everything and re do it
Biner on the bottom to allow disconnection of outer thingy and access to lower pockets.
Doesn't look too out of place on the pack which is nice:)
