Climbed Mount Whitney from Cottonwood meadows, New Army Pass, Rock Creek, Crabtree out to Whitney Portal.
These poles are light and quick to hike with, adding speed to your pace. I recommend these over adjustable ones because of their added strength. I lost my footing a couple time and placed all my weight on the poles, they did well, other poles probably would have collapsed.
