ABSTRACT:
A backpack has a pair of vertical posts, a base connected to the posts, and an extension that is slidable within the base. Various accessories such as tree claws and clamps for holding guns and bows are attachable to the base and extension. By sliding the extension within the base, the distance between the tree claws or clamps can be adjusted. A seat having a concave undersurface is pivotally connected to the post. When in a folded mode, the seat nests between the posts, and the seat undersurface bears against the back of the person to thereby make the backpack comfortable to carry.
