ZipFit Espresso Boot Liners

From ZipFit: "The mission was simple: make the best touring liner possible. The ZipFit Espresso is lighter weight for longer ski tours and high alpine expeditions. This is the culmination of years of design and testing with the world’s best ski mountaineers. At half the weight of a standard ZipFit, the Espresso will give you some pep in your step and keep your touring boots locked in for seasons to come."
