You can find the Summit 12 Alpine Touring Binding at the peak of Plum's performance. Plum's burliest binding, the Summit sports a solid 12 release rating for rowdier downhill riding, and it weighs a little over a pound each to keep you light on your feet during the ascent. The Summit transition from ski to hike modes by rotating the heel, and the brake retracts in ski mode similar to alpine bindings. The brake is also releasable, and there's a slot for crampons so you can customize. The baseplate adjusts 35mm to accommodate different boot lengths, and the toe is compatible with tech boots.
