Abstract: The present invention relates to a collapsible pole system. One embodiment of the present invention is directed at a collapsible ski pole with an improved locking system that minimizes operational failures. The collapsible ski pole includes at least two pole segments and a non-twisting locking mechanism disposed between each of the corresponding pole segments. The pole segments are cross-sectionally shaped to prevent rotation with respect to one another. Therefore, the non-twisting locking mechanisms cannot be misaligned or impeded as a result of the inadvertent twisting of the corresponding pole segments.
