CMI Expedition Ascender
Best heavy duty ascender for cold weather climbers wearing thick gloves.
This is a workhorse built for the coldest, most demanding vertical terrain. The oversized handle makes fumbling with thick gloves a thing of the past, though its robust, heavy-duty construction means you are trading off a bit of weight for absolute peace of mind on the wall.
