Marker Alpinist Adjustable 8 bindings are perfect for your touring trips into the ungroomed backcountry with great properties for hiking, climbing and descending. They have a DIN setting interval of 3 - 10. Your DIN setting should fall somewhere in the middle of the DIN setting interval for the bindings to function most effectively. Having a weight of only 535 g, these are very light bindings. We recommend choosing a brake arm that is 10 mm to 15 mm wider than the waist of your ski.
