With all the same sick features that classify any of Marker’s models, the 12.0 Free was created with your epic adventures in mind. The Marker 12.0 also boasts the same Stainless Steel Gliding AFD as the other models which is virtually unaffected by dirty or worn boot soles, negative sliding friction, outdoor temperature variations, combined-load backward-twisting falls or your downward weight on the AFD. The killer Biometric Pro toe system also keeps your safety in mind when you have a backwards-twisting fall but reducing your upward release force by 25% to 50% depending on how you set it.
