CMI Expedition Ascender
Best heavy duty ascender for climbers wearing thick winter gloves.
This dual-handled ascender turns grueling vertical climbs into a balanced, two-handed affair, significantly cutting down on forearm fatigue. While the extra handle adds a bit of bulk to your rack, the trade-off is a smoother, more efficient ascent that saves your energy for the work waiting at the top.
