The longer grips make the poles extremely useful in varied terrain offering comfortable alternative hand placements, they are particularly good when contouring steep slopes, negotiating deep snow or crossing rivers. The grips are lightweight, thermally insulating & absorb vibrations; the perfect trekking grip! The Thermolite poles feature the Speedlock system for easy height adjustment even when wearing gloves/mitts or when the poles are wet. We only sell Leki poles in pairs because to get the maximum benefit and efficiency they should only be used as a pair.
