The Mantis Climbing Sticks use X-Stand's Dual Spine technology allowing for two lightweight tubes to be used instead of the traditional single heavy wall tube. This makes the sticks much more durable and balanced. The Mantis Sticks have a unique design that pushes the foot pegs at an angle away from the tree, giving the user much more room for your whole boot without the tree getting in the way. The foot pegs have serrated edges with cut outs that will let mud, ice, or debris fall through without becoming slippery. Each stick will nest with the other to make the Mantis Sticks easy to pack. Engineered out of lightweight and strong Pro-Lite 6061 aircraft aluminum. Height: 31". Step width: 10". Step spacing: 12".
