Alpine Touring (AT) is specifically designed for ski touring in steep terrain. AT bindings allow the heel to be clipped down or released when climbing.
75mm ski gear is a type of binding system, typically with pins that fit into corresponding holes on the ski boot. This system is known for its reliability and durability, making it popular among backcountry and touring skiers.
Cross-country (Nordic) involves skiers using their own locomotion to travel across snow-covered terrain, without the use of ski lifts, offering a unique way to explore snowy landscapes through gliding on skis.
