Xcurve Frame

The revolutionary Xcurve Frame combines pack frame comfort and lightweight durability like never before. The anatomically matched curvature of the frame conforms to your lower-back and torso for unmatched load-bearing comfort. Using 4 carbon fiber composite stays in an "X" configuration, the Xcurve incorporates curvature to match the lumbar and upper back contours for increased weight distribution and comfort under heavy load. The unique "X" stay configuration increases both vertical frame strength and eliminates any lateral shift, especially for loads over 100 pounds. The Powerlock hip belt has forward assist pull with locking features to eliminate any webbing slip, even under the heaviest of loads. The tighter the belt is adjusted, the tighter the lock on the webbing. The Powerlock hip belt also has adjustable upper and lower tensioners to cup the hips and equalize pressure for the full width of the belt, regardless of body shape. Dual-density foam and improved belt shape all combine for more comfort under heavy loads.  The Xcurve shoulder straps offer increased foam density for comfort, increased vertical torso adjustment for shorter torsos, and increased width adjustment to better match the curvature over the shoulders.  The Xcurve is compatible with all past and present SG bags and uses the same load shelf features and function that defines all Stone Glacier hunting packs. The Xcurve was designed to provide the utmost comfort and stability under the heaviest of loads, a perfect blend of lightweight design and heavy load hauler.
