The Tyrolia Attack 14 GW Ski Bindings offer a deep DIN range of 4 - 14 for freeskiers! The Attack range is known for precise power transmission, light weight, and ease of stepping in even in powder, good news for skiers exploring the steep and deep. Note: if you intend to use an ISO 9523 Touring sole, you'll need to purchase the Attack 14 MN bindings designed to accommodate the extra sole thickness, not this model.
