We've all come to love the Kingpin for combining an alpine-grade binding into a touring package. The one area the Kingpin failed in was weight.

Marker took on the challenge and created a 245 gram binder that will quickly change the way you view the capabilities of a tech binder.

Given the design of the Alpinist, Marker has entered the world of light touring with a binding that will be safe and secure no matter what conditions you find yourself in. A moderately wide drill pattern allows for secure, durable heel placement that supports the binding at high speed or in tight turns. The Alpinist 8, when you're ready to load up on your next backcountry mission when weight is a factor.
