Like all the bindings in Marker's ultralight Alpinist line, the 12 Long Travel Binding won't weigh you down on long adventures far from the trailhead, yet it differs from the regular Alpinist in that it includes a brake instead of a leash, and offers 30-millimeters of adjustment to easily accommodate greater range of boot sole lengths. Its light weight and three different climbing levels make it incredibly efficient on the climbs, but it won't disappoint when it's time to strip skins and style your line, either. With higher release values than its younger sibling, the Alpinist 9 Long Travel, this binding is best suited to heavier-weight or more aggressive backcountry skiers. The Alpinist 12 Long Travel binding sports an adjustable 6-12 lateral release value for a consistent release you'll appreciate on the steeps, while the carbon-reinforced toe piece offers a smooth power transmission from boot to binding to ski. Marker designed the heel piece to adapt slightly to the flex of your ski, which further improves the connection between ski and binding, as well as the release consistency. If you think a touring binding this light is devoid of features that will enhance its dependability and ease of use when you're out in the backcountry, think again. The Alpinist has a visual step-in aid to guide your toe to the correct spot between the pins, and anti-ice pads to prevent snow from building up in the toe and heel piece. And, Marker designed this binding work with its ski crampons, just in case you're gearing up for a mission that might require some extra traction.
