The Pantin is a rope ascender that straps to the ankle, enabling a user to virtually grab rope with the foot. Employ a Pantin with the common doubled rope technique (DdRT) to experience the most efficient way to draw line out from behind the friction hitch. Once into the canopy, many climbers simply leave the Pantin in place, reemploying it as necessary. Compact and lightweight, the Pantin works on 11-13 mm lines. (each weighs 85 grams).
