A portable tree climbing device that provides secure hand grip and foot support to a climbing person without causing harmful damage to trees. The device is formed from a single sheet of rigid material and is attached to the tree with a commercially available strap and buckle assembly. The device is made progressively tighter about the tree's girth with the application of the weight of the user and has the inherent ability to retain this tight relationship with the tree after the user's weight has been removed.
