This ultralight and waterproof day pack has all the features needed for a fast and light summit push. An Airpurge strip allows for maximum compression, as the air-permeable fabric allows the complete evacuation of internal pressure. Radio frequency welded seams and reinforced fabric on the bottom and pocket area provides maximum strength and waterproofness. A mesh pocket accommodates a hydration bladder, and stretch cording and gear loops secure crampons and ice tools. Compression straps cinch down your load, and breathable mesh shoulder straps combine to offer a comfortable fit for alpine climbing and peak bagging.
