The Trigger 3D system on the Carbon 12 poles is incredibly convenient: once you place the straps on your hands, theres no need to remove them when you need to do something where the poles would just be in the way. They lock into the poles attachment and can be easily released not only in case of a fall but whenever you wish. Leki also offers gloves equipped with loops compatible with this system. These poles use very high-quality carbon fiber, and their design provides controlled flexibility. The 12 mm shaft is the thinnest in the range. - Material: Carbon PRC 1000 - Weight: 275g per pole - Shaft diameter: 12 mm - Flex Tip Short: Leki's standard tip, allowing easy basket changes - Trigger 3D ProG grip with comfortable 2K Supersoft foam - Cobra Alpine baskets
