The Atomic Colt 5 Gw Binding boasts everything your up-and-coming ski star needs from an alpine binding. What does your up-and-coming grom need you might ask. Easy. Retention, compatibility, and weight savings. These bindings offer a reliable max DIN of 4. 5 that holds little shredders in when they need to be and lets them out when the fall calls for it. Meanwhile, the GripWalk and Alpine compatibility works with the majority of modern youth boots, and the lightweight composite construction makes sure little legs stay fresh from first chair to last.
