Patagonia’s minimalist 45l climbing pack in grey/blue. From Patagonia: Our ambassadors' request: a super-clean climbing backpack stripped of everything but the features that matter most when you're pushing the limits on big alpine ascents. For moving fast in Alaska or the Karakoram, this function-driven pack carries the loads of a multiday kit without interfering with your ability to move efficiently. It features an integrated, asymmetrical spindrift collar that opens wide and closes in a single motion for fast packing. In good used condition with some discoloration from use as depicted in pictures.
