The ultralight and waterproof Drycomp Summit Sack 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. Sewn and taped seams, and reinforced fabric on the bottom and back area provide maximum strength and waterproof protection. Mesh side pockets accommodate water bottles, and gear loops secure ice tools. Compression straps cinch down your load, and padded shoulder straps ensure a comfortable fit for alpine climbing and peak bagging. Durable . Waterproof . Lightweight . Waterproof Roll Top Closure .
