The combination of lightweight, durable materials and intelligent design has made the Andinista the premier, most sought-after alpine mountaineering pack in the world. No other pack has seen as many technical ascents on the world’s highest mountains as the Andinista. Engineered for alpine style climbing, the Andinista weighs a mere 3 lbs 8 oz without the bivy pad, balances well, and moves with your body as you climb. Side compression zippers crunch the bag down to a manageable day pack size. The WT Tactical Andinista pack has become a recent favorite of the SOF community.
