CMI Expedition Ascender

4.6

Best heavy duty ascender for climbers using thick winter gloves.

This dual-handled ascender is built for long, demanding hauls where stability matters more than weight. The oversized grips make it a dream for cold-weather work with bulky gloves, though the robust, heavy-duty construction means you’ll definitely feel the extra mass on your harness during long approaches.
