CMI Expedition Ascender
Best heavy duty ascender for climbers using thick gloves in cold conditions.
This ascender turns grueling vertical climbs into a balanced, two-handed affair, significantly cutting down on fatigue during long days in the canopy. You sacrifice the minimalist profile of a single-handle tool, but the trade-off is a much more stable, efficient ascent that keeps you fresher for the work that actually matters.
