Black Diamond designed the Predator Backpack for alpine and ice climbers who need a functional pack with all the features needed for the mountains most demanding routes. This durable pack uses 1260D nylon to take on the onslaught of hauling, ice tools, crampons, rock fall, and all the other fun stuff the mountain uses to attack your pack. The Predator Backpack holds enough gear for a three-day push on a technical route, and securely carries your ice tools and crampons during the hike from base camp. Strip this Black Diamond pack of its lid, aluminum frame, and waist-belt to drop the weight from 3lb 15oz to 2lb 3oz when you really need to shave grams. Backpacker Magazine labeled this pack as best for all season versatility, so you know you can count on it for nearly anything.
