Designed especially for Tara backpack. It uses its bottom tabs (with 7cm= almost 3inches spacing)  for bottom attachment. Remove a buckle from upper compression straps on your backpack and pass webbing through the buckles included with this beaver tail. When fully filled it allows a Tara pack to free stand. Put smaller items inside the pouch for secure storage. Put larger items (helmet, jacket etc) behind the beaver tail.

Do your own judgement if it fits other backpack models.
