The Carbon SS Climbing sticks are a single, continuous piece of carbon fiber composite. No moving parts, no hardware, and nothing to come loose. The material is extremely rigid, so bent stand offs are no longer possible. The stack-ability of the new Carbon SS Climbing Sticks keeps your gear within your frame, making access through the thickest of woods a breeze. Replacing the versa button, the new attachment wings allow the sticks to stack flat, making them compact for saddle hunters & tree stand hunters. Stronger than many steels & 40% lighter than aluminum. The new Carbon SS Climbing Sticks maintain strength in brittle cold or extreme heat, ensuring reliability during the harshest of hunts.
